4. DESCRIPTION
NOTE
Refer to specifi c data sheets for fl ow capacities and vacuum capacities.
NOTE
Refer to diagrams in this manual for proper rotation and orientation in inlet
and discharge.
Tuthill V acuum & Blower Systems model 4000 and 5500 Series rotary lobe blowers are positive displacement
type units, whose pumping capacity is determined by size, operating speed, and differential pressure
conditions. Blowers employ rotors rotating in opposite directions within a housing closed at the ends by
end plates.
Effective sealing of the inlet to the discharge is accomplished through the use of very small operating
clearances. The resulting absence of moving contact eliminates the need for any internal lubrication.
Clearances between the rotors during rotation are maintained by a pair of accurately machined helical
timing gears, mounted on the two shafts extended outside the air chamber. The intermeshing rotary lobes
are designed to rotate and trap air or gas between each rotor and the housing. As the rotor lobes rotate
past the edge of the suction port, the trapped air or gas is essentially at suction pressure and temperature.
Since the blower is a constant volume device, the trapped air remains at suction pressure until the leading
rotor lobe opens into the discharge port. The close clearances between the rotors inhibit back slippage of
the trapped volume from between the rotors and the trapped volume is forced into the discharge piping.
Compression occurs not internal to the blower, but by the amount of restriction, either downstream of the
blower discharge port, or upstream of the blower inlet port.
5
Figure 1 illustrates that the air
moves not between the rotors but
between the rotors and the side
of the housing. Also, the machine
is bi-directional, meaning that the
direction of rotation of the blower
can make either side the inlet or
discharge. See also the Flow Direction by Rotation section
below.
INLETINLETINLET
No attempt should ever be made
to control capacity by means of
DISCHARGEDISCHARGEDISCHARGE
Figure 1 - Illustration of general operation principle
a throttle valve in the intake or
discharge piping. This will increase the power load on the drive system, increase operating temperatures,
and can overload and/or seriously damage the blower. Likewise, if a possibility exists that fl ow to the blower
inlet may be cut off during normal operation of a process, then an adequate vacuum relief valve must be
installed near the blower. A pressure type relief valve in the discharge line near the blower is also strongly
recommended for protection against cutoff or blocking in this line. Check valves should also be used on
every blower when more than one blower is connected to a discharge line. This is for both safety and
operating conditions.
When a belt drive is employed, blower speed, if necessary, can usually be adjusted to obtain desired
capacity by changing the diameter of one or both sheaves, or by using a vari-speed motor pulley. In a
direct coupled arrangement, a variable speed motor or transmission is required, or excess air or gas may
be blown off through a manually controlled unloading valve and silencer. Gas units can use bypasses, but
some applications may require additional cooling. If there is a large volume of high pressure air or gas
downstream of the blower, a check valve in the piping downstream of the blower will protect the blower from
overspeeding in a backward direction upon shutdown.
Consult your Tuthill Vacuum & Blower Systems sales professional if questions arise.

5. INSTALLATION
5.1 GENERAL
NOTE
Specially ordered blowers with nonstandard construction, or with rotor end
clearances greater than shown within the Assembly Clearances table, will
not have the operating limits specifi ed here. Contact your Tuthill Vacuum &
Blower Systems sales representative for specifi c information.
NOTE
Special attention must be paid when a blower has a higher than standard
ambient suction temperature. Special recommendations for operating
parameters and/or additional cooling may be recommended. Consult the
factory or local representative for appropriate information.
DANGER
The blower is not intended to be used with explosive products or in explosive
environments.
DANGER
It is the responsibility of the installer to assure that proper guarding is in
place and compliant with all applicable regulatory requirements.
WARNING
The bare shaft blower can generate excessive noise. Methods to reduce
the noise levels by installing inlet and outlet silencers will be required. Even
with inlet and outlet silencers, hearing protection will be required.
WARNING
Customers are warned to provide adequate protection, warning and safety
equipment necessary to protect personnel against hazards in the installation
and operation of this equipment in the system or facility.
WARNING
The standard MAWP is per Table 2. The MAWP shall not be exceeded
unless specifi c factory testing of the pressure containing components of the
blower has been performed.
WARNING
Table 2 states the maximum operating speed in RPM (rotations per minute)
and maximum temperature. Do not exceed these limits. The installation of
the blower shall take these critical operating parameters into account and
adequate control features implemented.
WARNING
Upon completion of the installation, and before applying power, rotate the
drive shaft by hand. It must move freely. If it does not, look for uneven
mounting, piping strain, excessive belt tension or coupling misalignment or
any other cause of binding. If blower is removed and still does not move
freely, check inside the blower housing for foreign material.
8
NOTE
Remove the protective covers from the shaft and inspect for damage.
Carefully check to ensure that no transit damage has been sustained. If damage has occurred from
shipment a claim must be fi led with the carrier immediately; preserve the shipping container for inspection
by the carrier.
NOTE
In the event that your unit sustains damage while being shipped to your
facility, do not return it to the factory without fi rst obtaining shipping
instructions from us.
Protective covers and plugs should not be removed until the connection is being made. Mount the blower
on a fl at, level surface. We recommend a baseplate that is a rigid, solidly supported, and structurally
sound. Shim under the legs where necessary so that each leg of the blower supports an equal share of the
blower weight. This is necessary to prevent eventual twisting of the blower. Make sure feet rest evenly on
the mounting surface before fastening down. Twisting or cramping the blower in mounting will cause rotor
contact and binding during operation, resulting in a condition called “soft foot”. (See the Soft Foot section
of this manual for further details and preventative measures.)
A unit that is factory mounted on a base, should not require the above adjustments. However, since
the assembly can become twisted in shipping or installation, checking for soft foot should be done after
installation of the base. Shims may be needed for alignment. Loosen the foot hold-down screws to check
foot contact with the mounting surface. The base should be mounted on a solid foundation or heavy fl ooring,
using shims as necessary at bolting points to prevent warping the assembly. (Also refer to the Foundation
section.)
Transmission of small operating vibrations to a support structure may be objectionable in some cases. Use
of vibration isolators or vibration absorbing materials can be effective in overcoming this problem. To avoid
casing distortion, the treatment used should be applied under the common motor/blower base or mounting
plate, rather than directly under the feet alone.
Piping should be accurately squared with the blower and supported independently. Stress imparted from
incorrectly aligned piping or mounting will create problems with bearing and seal life, possibly leading
to premature internal contact. The blower should sit stress free and evenly on its supporting surface.
Care should be taken to evenly tighten the
mounting bolts to not impart undue stress
into the blower. Stress can be checked in a

Use only clean new pipe and make certain it
is free of scale, cuttings, weld beads, dirt, or
any other foreign material. To guard against
damage to the blower, insure that an inlet
fi lter is used. Make provisions to clean the
fi lter of collected debris after a few hours of
operation and periodically thereafter. (See
the Piping Connections section for additional
details.)

of throttle or shut-off valves in either discharge or intake piping. If it is possible for air fl ow to be cut off in
either of these lines, make provisions to add a pressure and/or vacuum relief valve. In some installations,
it may be desirable to use only an inlet silencer-cleaner supported directly from the blower connection.
Weight of accessories and piping must be kept to a minimum to prevent blower casing distortion. Weights in
excess of 10% of blower weight should be supported independently of blower and connected with a fl exible
hose or connectors. (The approximate weight of your unit is included within the Specifi cations table.)
A blower may be driven by direct-coupling to the driver or by V-belt drive, to obtain other speeds within
approved range. (See the Motor Drives section for more information.)
Blowers from Tuthill Vacuum & Blower Systems are internally and externally treated after factory assembly
and testing to protect against rusting in normal atmospheric conditions prior to installation. The maximum
period of internal protection is considered to be up to 6 months under average conditions, provided closing
plugs and seals are not removed. Protection against chemical or salt water atmosphere is not provided.
Avoid opening the blower until ready to begin installation, as protection will be quickly lost due to evaporation.
(For recommended preparations for long term storage (longer than 6 months), please see the Long Term Storage section in this manual.)
5.1.1 LOCATION
Install your blower in a room or outdoor area that supplies adequate space and lighting for routine
maintenance. Indoor installation areas should be well ventilated and kept as cool as possible, because
operating the unit at elevated temperatures can result in nuisance overload or temperature shutdowns. An
unprotected outdoor installation is only satisfactory when correct lubrication for expected temperatures is
provided, as per the Recommended Lubricants section in this manual.
5.1.2 BLOWER AIR INTAKE
To minimize maintenance, supply your blower with the cleanest air possible. It is important that the air does
not contain any fl ammable or toxic gases, as the blower will concentrate these gases. This could result in
damage to the unit and surrounding property, lead to personal injury or death. Do not block or restrict the
opening or the blower and/or motor may overheat and fail.
Do not use blowers on explosive or hazardous gases. Each size blower has limits on pressure differential,
running speed, and discharge temperature. These limits must not be exceeded. Consult Table 2 for details
pertaining to the allowable performance criteria.
If it is necessary to take air from a remote source, such as in a vacuum application, the piping should be
at least the same diameter of the blower inlet. For distances greater than 20 feet (6 m) the pipe diameter
should be enlarged to reduce inlet restriction. Excessive restriction will reduce the effi ciency of the blower
and elevate its discharge temperature. The piping used should also be corrosion resistant, and free of
scale and dirt. The inlet should be covered to keep out precipitation, insects, and small animals. Vacuum
kits are available.
10
5.1.3 SOFT FOOT
Soft foot is a condition in which one of the blower feet does not sit
fl at on the base. Usually, this is due to irregularities in the surface
to which the blower is mounted. When you tighten the bolt on the
foot, the blower will distort slightly, but enough to cause problems
with bearing and seal life, and premature internal contact between
the rotors and the housing.

5.2 SAFETY
Tuthill V acuum & Blower Systems recommends the use of relief valves to protect against excessive pressure
or vacuum conditions. These valves should be tested at initial start-up to be sure they are properly adjusted
to relieve at or below the maximum pressure differential rating of the blower.
DANGER
It is the responsibility of the installer to assure that proper guarding is in
place and compliant with all applicable regulatory requirements.
DANGER
Internal and external rotating parts of the blower and driving equipment can
produce serious physical injuries. The blower should never be run with the
inlet or discharge piping removed. If it becomes necessary to inspect the
rotating parts of the blower or to change V-belts, be absolutely sure that all
power to the motor controls has been shut off, the motor controls are locked
out, and properly tagged before proceeding.
DANGER
Assure that properly sized vacuum breaks/relief valves are used on the inlet
side of the blower. Also assure that properly sized pressure relief valves
are used on the outlet of the blower. The sizing shall be such to assure that
the proper fl ow can be achieved without exceeding the rated vacuum and
pressure ratings.
DANGER
Blower housing and associated piping or accessories may become hot
enough to cause major skin burns on contact.
11
WARNING
Use lock out/tag out procedures to disable the electrical energy source
before any service or work is done on the blower.
WARNING
Avoid extended exposure in close proximity to machinery with high intensity
noise levels. Wear adequate ear protection.
NOTE
Use proper care and good procedures in handling, lifting, installing,
5.3 LUBRICATION
Every blower from Tuthill Vacuum & Blower Systems is factory tested, oil drained and shipped dry to its
installation point. Both independent oil reservoirs must be fi lled to the proper level before operation. Oil
reservoirs are under vacuum.
Shaft bearings at the gear end of the blower are splash lubricated by one or both gears dipping into an oil
reservoir formed in the gear end plate and cover. Shaft bearings at the drive end of the blower are lubricated
by a slinger assembly dipping into an oil reservoir. Before starting the blower, fi ll oil sumps as shown below
within the Filling Procedure section.
operating, and maintaining the equipment.
Add oil to the blower in the quantity shown within the Specifi cations Table. The oil level must be maintained
within the notched area of the sight glass. See Figure 5. Lower drive units have “bull’s eye” type oil level
gauges. Maintain oil levels at the center of the glass.
WARNING
Never attempt to change or add lubrication while the blower is running.
Failure to heed this warning could result in damage to the equipment or
personal injury. Oil must be checked when the blower is NOT running.
WARNING
Properly dispose of the spent lubricants. Refer to the manufacturer of the
lubricant and any regulations to assure proper and safe disposal.
WARNING
Do not start the blower until you are sure oil has been put in the gear
housing and rear cover. Operation of the blower without proper lubrication
will cause the blower to fail and void the warranty.
NOTE
Assure oil is compatible with copper/yellow metals (if equipped with cooling
coils).
12
NOTE
Refer to Table 1 for oil capacities.
5.3.1 FILLING PROCEDURE
See Figure 5. Recommended lubricants are shown on page 35.
1. Remove fi ll plugs or breathers from both gear end and drive end plates.
2. SLOWLY pour oil through fi ll until oil appears in the oil sight glass. Bring oil level to center of sight glass.
3. Verify oil level is at proper level in BOTH gear end and drive end sight glasses.
4. Replace fi ll plugs or breathers that were removed in step 1.
What is the functional detriment if the “wrong oil” is used?
The lubricant is selected based on bearing and gear speed, and operating temperature. Too light
of a lubricant increases wear by not separating the sliding surfaces and it will not remove the heat
adequately . If the lubricant is too thick, the drag in the bearings is increased causing them to run hotter .
Since it is thicker, it will not fl ow as readily into the gears and it will reduce the available backlash.
Lubricants at our conditions are incompressible.
OIL LEVEL
GAUGE
(1) EA
END PLATE
What is the functional detriment if the oil is not serviced?
If the lubricant is not serviced at the proper interval the shearing action in the bearing and the gears will
begin to take their toll and the lubricant will thicken, making matters worse. The unit will run hotter and
the wear on running surfaces will increase. Generally, the lubricant will appear dirtier, this is actually
material rubbed off the unit’s components. The discoloration comes from overheating the additive
package. An indicator of the breakdown of a lubricant is the increase in the TAN (Total Acid Number),
and a change in the base viscosity of ten percent.
Several things are happening as the lubricant goes through the unit. First, it is absorbing frictional
energy in the form of heat. This heat has to be dissipated through either surface contact with cooler
materials, or in a rest volume of lubricant. While reducing the friction, the lubricant is also going through
a shearing process and the molecular structure is broken down.
The result is that the lubricant will begin to thicken because of the shorter molecular chains and the drop
out of additive packages. The thickened lubricant will cause more drag, increasing the friction and heat,
and further degrading the lubricant.
Operation of the blower (environment, run time, speed, and pressure) has a direct effect on duty cycles.
Our published cycles are based on worst-case conditions.
13
5.3.3 HAZARDS ASSOCIATED WITH BREAKDOWN OR IGNITION OF LUBRICATION
DANGER
There is a risk associated with the lubrication media breaking down and
resulting in a hazardous fl uid or vapor. There may also be a hazard
associated with the ignition of the lubrication media. Refer to the lubrication
manufacture’s applicable instruction for safety precautions.
5.4 PIPING CONNECTIONS
WARNING
Pipe loading on the blower should be negligible as pipe loading can cause
distortion of the blower. Use proper supports and pipe hangers to assure
that there is no loading.
NOTE
Remove the protective covers from the inlet and outlet ports and inspect for
Inlet and outlet connections on all blowers are large enough to handle maximum volume with minimum
friction loss. Maintain same diameter piping. Silencers must not be supported by the blower. Stress loads
and bending moments must be avoided.
dirt and foreign material.
Be certain all piping is clean internally before connecting to the blower. We recommend placing a 16-mesh
wire screen backed with hardware cloth at or near the inlet connections for the fi rst 50 hours of use until the
system is clean. Make provisions to clean the screen after a few hours of operation and completely discard
it once the system is clean, as it will eventually deteriorate and small pieces going into the blower can cause
serious damage. A horizontal or vertical air fl ow piping confi guration is easily achieved by rearranging the
mounting feet position.
HAZARDS ASSOCIATED WITH HAZARDOUS PROCESS FLUIDS
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate,
sealing between pipe joints is adequate for the process fl uids and proper
process and pressure protection devices are in place. It is also the
responsibility of the installer to assure that process gasses are not vented
in a manner that would be hazardous.
Refer to the manufacturer of the process media to assure that proper safety
precautions are in place.
5.4.1 BLOCKAGE OR RESTRICTION
WARNING
Damage to the blower could occur if there is blockage in the inlet or outlet
ports or piping. Care should be taken when installing the blower to assure
that there are no foreign objects or restrictions in the ports or piping.
14
5.5 COOLING COILS (OPTIONAL)
CAUTION
If the blower is to be located outdoors or in a building where the temperature
surrounding the blower or the water supply and return piping can fall below
35°F (2°C), then care must be taken to ensure that the water (or other
cooling liquid) does not freeze and cause damage. Cooling coils must be
drained of liquid during downtime unless a recirculating unit using a glycol
mixture has been installed.
NOTE
Water cooled endplates are discontinued. Consult factory for connection
details.
NOTE
Units are never shipped from the manufacturer with liquid in the end plates
Blowers supplied with cooling coils are identifi ed by the letter located in the tenth position of the complete
blower model number.
Blowers supplied with coiling coils can also be identifi ed by the hose that connects the top of the gear (drive)
end cover to the bottom of the free (non-drive) end cover. See Figures 5 and 6 for details. Tuthill Vacuum
& Blower Systems recommends water cooling for blowers in applications where the blower operates with
discharge temperatures of 250° F (120° C) for periods of 4 hours or greater per day. The use of water
cooling reduces oil temperature and improves oil viscosity for better lubrication. Generally, a water fl ow or
0.5-1.0 GPM (1.9-3.8 L/min) is suffi cient to maintain oil temperatures of 150° F (65° C) or below. Do not
allow water pressure to exceed 75 PSIG (510 kPa g).

Proper gap between coupling halves must be established according to coupling manufacturers instructions
with the motor armature. This will minimize the change for end thrust on the blower shaft. All direct coupled
base mounted units must be re-aligned and greased after fi eld installation.
5.7 MOTOR DRIVES
Two drive connections commonly used are direct drive and V-belt drive.
5.7.1 DIRECT COUPLED
When installing the motor directly to the blower, align shafts to coupling in accordance with the coupling
manufacturer’s instructions. Blowers shipped with motor directly coupled and mounted on a common base
have been aligned prior to shipment and normally no further alignment is necessary. However, alignment
should be checked and adjustments made if necessary prior to starting the unit.
Coupling halves must correctly fi t the blower and drive shafts so that only light tapping is required to install
each half. The two shafts must be accurately aligned, A direct coupled blower and motor must be aligned
with the two shafts not having more than .005” (13 mm) T.I.R. (Total Indicator Reading). Face must be
aligned within .002”(.05 mm) .
Proper gap between coupling halves must be established according to coupling manufacturers instructions
with the motor armature. This will minimize the change for end thrust on the blower shaft. All direct coupled
base mounted units must be re-aligned and greased after fi eld installation.
5.7.2 V-BELTS
If the motor and blower are V-belt connected, the sheaves on both motor and blower shafts, should be as
close to the shaft bearings as possible. Blower Sheave is not more than 1/4” (6.5 mm) from the blower
drive end cover. The drive sheave is as close to the driver bearing as possible. Care should be taken when
installing sheaves on the blower and motor shafts. The face of the should be accurately in line to minimize
belt wear.
Adjust the belt tension to the to the manufactures specifi cations using a belt tension tester. New belts should
be checked for proper tension after 24 hours of run time. When manufacturer data is not available industry
guidelines are 1/64 inch defl ection for each inch of span at 8 to 10 pounds of force in the center of the belt.
Insuffi cient tensioning is often indicated by slipping (squealing) at start up. Belt dressing should not be
used on V-belts. Sheaves and V-belts should
remain free of oil and grease. Tension should be
removed from belts if the drive is to be inactive
for an extended period of time. For more specifi c
information consult the drive manufacturer. In a
v-belt drive, the blower sheave must fi t its shaft
accurately, run true, and be mounted as close

Check blower after installation and before applying power by rotating the drive shaft by hand. If it does not
rotate freely, look for uneven mounting, piping strain, excessive belt tension, or coupling misalignment.
Check blower at this time to insure oil was added to the reservoirs.
5.7.3 SETTING V-BELT TENSION
Proper belt tension is essential to long blower life. The following diagrams and procedures are provided to
aid in fi eld adjusting V-belts (when blower is so equipped) for maximum performance. A visual inspection of
the V-belt drive should yield the appearance shown in Figure 7.
Factors outside the control of the belt tensioning system used on an individual blower package assembly
may contribute to decreased belt life, such as environmental factors, and quality of the belts installed. This
can cause wear of the belts beyond the ability of the tensioning system to compensate.
As such, it is recommended to check belt tension monthly and make any manual adjustments found
necessary.
1. Turn off and lock out power.
2. Remove the fasteners from the belt guard (if equipped)
3. Remove the belt guard.
4. Check and adjust the belt tension as necessary. It should be 1/64” defl ection per inch of span (0.157
mm) defl ection per centimeter of span) between sheaves, with 8-10 lbs. (3.6-4.5 kg) force applied at
center point of the top section of belt.
5. Install the belt guard, making sure that all drive components are free of contact with the guard.
6. Install belt guard fasteners removed in step 2.

1. The external lube tank is equipped with an oil fi lter which has a replaceable element. The part number
for the element is 91999-1.
2. Each tank has an oil pressure relief valve which is set at the factory at 12 - 15 PSIG (80 - 100 kPa g)
and normally requires no adjustment. If an adjustment becomes necessary , remove the cap and adjust
the screw. Clockwise will increase pressure, and counterclockwise will reduce pressure.
3. Oil tank should be on a level surface with return connections of tank below the blower return connections
at approximately 2 inches drop per foot (16.5 cm drop per meter). Each end of blower shall have
separate return hose lines (3/4” [19 mm] I.D. minimum) not over six feet from farthest blower.
4. The oil supply hose and connections must be kept free of dirt and foreign material during installation to
5. Make sure motor pump wiring connection is for correct rotation as indicated by arrow on motor.
6. Tanks equipped with heat exchangers should have water fl ow direction counter to oil fl ow . Required
water fl ow rate is approximately 0.25 - 1.0 GPM (0.95 - 3.8 L/min) depending upon blower operating
condition (oil sump temperature should not exceed 250° F [120° C] maximum).
CAUTION
Fill both ends of blower with oil to proper level, then operate oil supply
system, and be sure oil is returning from both blower return hoses prior to
starting blower.
5.9 MOTOR AND ELECTRICAL CONNECTIONS
WARNING
The motor and connections shall be protected to assure that product and
environmental condensation does not come in contact with the electrical
connections.
NOTE
It is the responsibility of the installer to assure that the motor is in compliance
Wire the motor and other electrical devices such as solenoid valves and temperature switch to the proper
voltage and amperage as indicated on the nameplate of each component being wired. Turn the blower by
hand after wiring is completed to determine that there are no obstructions and if the blower turns freely;
then momentarily start the blower to check the direction of rotation. Figure 2 shows direction of air fl ow in
relation to rotor rotation. The air fl ow direction can be reversed by reversing the appropriate motor leads.
with the latest edition of IEC 60204-1 and all electrical connections
performed per IEC 60204-1, this includes over current protection.
19
6. OPERATION
6.1 GENERAL
DANGER
The blower is not intended to be used with explosive products or in explosive
environments.
WARNING
Do not operate without guards in place.
WARNING
Maximum operating speed: Table 2 states the maximum operating speed in
RPM (rotations per minute), the maximum pressure differential, maximum
vacuum and maximum temperature rise. Do not exceed these limits.
Before starting the blower for the fi rst time under power, recheck the installation thoroughly to reduce the
likelihood of troubles. Use the following check list as a guide, but also consider any other special conditions
in your installation.
1. Be certain no bolts, rags, or dirt have been left in blower.
2. Be certain that inlet piping is free of debris. If an open outdoor air intake is used, be sure the opening is
clean and protected by an inlet fi lter. This also applies to indoor use.
3. If installation is not recent, check blower leveling, drive alignment, belt tension, and tightness of all
mounting bolts.
4. Be certain the proper volume of oil is in the oil reservoir chambers.
5. Be certain the driving motor is properly lubricated, and that it is connected through suitable electrical
overload devices.
6. With electrical power off and locked out to prevent accidental starting, rotate blower shaft several times
by hand to make sure blower is rotating freely. Unevenness or tight spots is an indication of a problem
that should be corrected before progressing.
7. Check motor rotation by momentarily pushing the start button and check fl ow direction of the blower.
Reverse the motor connections if fl ow is in the wrong direction.
Initial operation should be carried out under “no load” conditions by opening all valves and venting the
discharge to atmosphere, if possible. Then start motor briefl y, listen for unusual noises, and check that the
blower coasts freely to a stop. If no problem appears, repeat this check, and let the motor run a little longer.
If any questions exist, investigate before proceeding further.
Assuming all tests are satisfactory, the blower will now be ready for continuous full load operation. During
the fi rst several days, make periodic checks to determine that all conditions remain acceptable and steady.
These checks may be particularly important if the blower is part of a process system where conditions may
vary . At the fi rst opportunity , stop the blower and clean or remove inlet fi lter . Also, recheck leveling, coupling
alignment or belt tension, and mountlng bolts for tightness.
20
6.2 START-UP CHECKLIST
We recommend that these startup procedures be followed in sequence and checked off ( ) in the
boxes provided in any of the following cases:
• During initial installation
• After any shutdown period
DATES CHECKED:
Check the unit for proper lubrication. Proper oil level cannot be over-emphasized.
Refer to the Lubrication section. Please see Recommended Lubricants for information
on acceptable lubricants for your product.
Check V-belt drive for proper belt alignment and tension.
Carefully turn the rotors by hand to be certain they do not bind.
“Bump” the unit with the motor to check rotation (counter-clockwise [CCW] when
facing shaft) and to be certain it turns freely and smoothly.
Start the unit and operate it for 30 minutes at no load. During this time, feel the
cylinder for hot spots. If minor hot spots occur, refer to the Troubleshooting chart.
• After maintenance work has been performed
• After blower has been moved to a new location
WARNING
Disconnect power. Make certain power is off and locked out before touching
any rotating element of the blower, motor, or drive components.
Apply the load and observe the operation of the unit for one hour.
If minor malfunctions occur, discontinue operation and refer to the Troubleshooting
chart.
6.3 OPERATING
The upper temperature limit for blower operation is 400° F (205° C) measured in the exhaust gas stream
with a low mass thermocouple. When this temperature limit switch is installed, as the temperature exceeds
the predetermined temperature, the blower motor will stop and cannot be restarted until the temperature
drops below the trip setting of the temperature switch.
DANGER
The blower is not intended to be used with explosive products or in explosive
environments.
WARNING
Physical harm may occur if human body parts are in contact or exposed to
the process vacuum. Assure that all connections are protected from human
contact.
WARNING
If rated vacuum or pressure levels are exceeded, process fl uids will migrate
to other parts of the blower and system.
21
6.4 STOPPING
CAUTION
Do not touch hot surfaces.
The upper limit of the blower operation is 400º F (205º C). Do not touch
the blower while it is in operation and assure blower is cool when not in
operation.
CAUTION
Use of a thermowell insulates the thermocouple. Invalid and delayed
readings will result. This can result in ineffective protection devices.
NOTE
The upper temperature limits are not intended for continuous operation.
Consult with factory for detailed information assistance.
CAUTION
Do not stop the blower if there are high outlet pressures in the outlet piping.
Unload the outlet piping prior to shutting down the blower.
Stop the blower by turning off the motor. Isolate the blower from the vacuum system and vent the blower
to atmosphere. Turn off the cooling water, if water cooled. Stop the backing pump. Refer to component
instruction manual.
6.5 METHANE GAS APPLICATIONS
Instructions for injecting fuel oil, kerosene, and lube oil into blowers sludged
by methane digester (sewage) gas: Some sewage gases will adhere to the
rotors in a gas blower. If enough sludge from the gas being pumped builds
up on the rotors, it destroys the clearances between the rotors. The build-up
can cause the blower to clatter and eventually freeze up when the rotors no
longer have clearance to turn. This can be easily prevented by periodically
fl ushing the blower with a mixture of 75% kerosene or fuel oil and 25%
lubricating oil. The kerosene or fuel oil dissolves the sludge buildup and the
lubricating oil coats the rotors to slow the build-up. The mixture should be
injected on the inlet side through a valve set to feed a gallon of mixture in 1520 minutes. On units regularly fl ushed, once a week is suffi cient. If the unit
is dirty , it should be fl ushed daily until the hard build-up is removed then put
on a weekly cycle. In very dirty gas installations, the cycle must be varied to
meet the demand.
CONTROL
Figure 10 - Flushing Diagram
VALV E
FLUSHING
FLUID
6.6 WATER INJECTED BLOWERS
Water injected into the inlet of a blower operating on vacuum service will cool the blower . The water absorbs
the heat of compression as it passes through the unit along with the air/gas being compressed. A blower
cooled in this manner can operate safely at higher vacuums or higher inlet temperatures than a normally
uncooled unit.
The amount of water required depends on the inlet air/gas temperature, inlet vacuum, water temperature,
and the maximum discharge temperature desired. Check with the factory or sales representative for
additional guidance.
22
6.6.1 OPERATION
1. Check oil level in sight glass of blower and assure all fi ttings are tight.
2. Check the water injection system to assure water is available.
3. Operate the blower dry for a few minutes at no load to check correct rotation and smooth operation.
4. Turn water on and adjust fl ow as recommended for the individual blower. Assure water discharges
freely from the outlet piping.
5. Apply vacuum and observe operation at the desired inlet condition.
6.6.2 SHUTDOWN
1. The blower can be shutdown for brief periods by relieving the inlet vacuum, shutting the water off, and
then stopping the unit.
2. Rusting during a slightly longer shutdown period can be avoided by operating the blower under a partial
vacuum without the water injection, allowing the blower to heat within safe limits. The heat will tend to
drive off residual moisture.
3. For extended shutdown, oil may be injected into the inlet of the heated blower just prior to shutting
the blower down. The oil will provide a protective coating on the internals. Insure that the water is
completely shut off after shutdown.
4. Special coatings or platings are available to minimize rusting or corrosion in applications where units
can remain wet.
Vertical fl ow units with two-lobed, plugged rotors should always be used. Always orient system such that
the blower intake is at the top and discharge at the bottom.
CAUTION
Water injection can cause lime build-up on rotors. Check water supply for
hardness. The use of water softeners, other chemicals, or distilled water
may be necessary to prevent or remove this build-up. However, due to the
wide variations in mineral content, pH, and chemical content of water that
can be injected, Tuthill Vacuum & Blower Systems cannot be responsible
for damage which may result should this build-up occur. Units should be
inspected regularly to determine any problems.
NOTE
6.7 RECOMMENDED SHUTDOWN PROCEDURE TO MINIMIZE RISK OF FREEZING OR
CORROSION
When high humidity or moisture is present in an air piping system, condensation of water can occur after
the blower is shut down and the blower begins to cool. This creates an environment favorable to corrosion
of the iron internal surfaces, or in cold weather, the formation of ice. Either of these conditions can close the
operating clearances, causing the blower to fail upon future start-up.
The following shutdown procedure outlined below minimizes the risk of moisture condensation, corrosion
and freezing.
For liquid injection other than water, consult the factory.
NOTE
Care must be taken so as not to overload or overheat the blower during this
1. Isolate the blower from the moist system piping, allowing the blower to intake atmospheric air. Operate
the blower under a slight load allowing the blower to heat within safe limits. The heat generated by the
blower will quickly evaporate residual moisture.
procedure.
23
2. For carpet cleaning applications, after the work is completed, simply allow the blower to run a few (3-5)
minutes with the suction hose and wand attached. The suction hose and wand will provide enough load
to the blower to evaporate the moisture quickly.
3. For extended shutdown, inject a small amount of a light lubricating oil such as 3-in-One
®
or a spray
lubricant such as WD-40® into the inlet of the blower just prior to shutdown. (3-in-One and WD-40 are registered trademarks of WD-40 Company.) The lubricant will provide an excellent protective coating
on the internal surfaces. If using a spray lubricant, exercise care to prevent the applicator tube from
getting sucked into the blower. The applicator tube will damage the blower, most likely to the point that
repair would be required.
4. If the blower is being taken out of commission for an extended period of time, please also refer to the
“Long Term Storage” section of this manual.
7. MAINTENANCE
7.1 GENERAL
Regular inspection of your blower and its installation, along with complete checks on operating conditions
will pay dividends in added life and usefulness. Also, service the drive per manufacturer’s instructions and
lubricate the coupling or check belt drive tension. By use of thermometers and gauges, make sure that
blower operating temperature and pressure remain within allowed limits.
DANGER
The blower and parts may contain hazardous media. Assure that pump and
parts are evacuated of hazardous media prior to servicing.
CAUTION
The electrical service must be isolated and de-energized prior to
maintenance. Apply appropriate procedures to assure electrical supply is
de-energized and cannot be inadvertently energized during maintenance.
Assure piping and product is isolated prior to maintenance of blower. Apply
appropriate procedures to assure piping and product is isolated and that
inadvertent opening of valves cannot occur during maintenance.
CAUTION
During routine maintenance, inspect and assure that guards are in place
and secure.
Particular attention should be paid to lubrication of timing gears and bearings in accordance with comments
under the Lubrication section.
When a blower is taken out of service, it may require internal protection against rusting or corrosion. The
need for such protection must be a matter of judgment based on existing conditions as well as length
of down time. Under atmospheric conditions producing rapid corrosion, the blower should be protected
immediately. Refer to the Long Term Storage section for more details.
24
7.2 REGULAR MAINTENANCE
A good maintenance program will add years of service to your blower.
A newly installed blower should be checked frequently during the fi rst month of operation, especially
lubrication. With blower at rest, check oil level in both the gear (drive) end and free (non-drive) end of the
blower and add oil as needed. Complete oil changes are recommended every 1000-1200 operating hours,
or more frequently depending on the type of oil and operating temperature. Also change the oil more
frequently if pumping corrosive vapors or where excessive operating temperatures are encountered. The
following is recommended as a minimum maintenance program.
DAILYWEEKLYMONTHLY
1. Check and maintain oil level,
and add oil as necessary.
2. Check for unusual noise or
vibration (See Troubleshooting)
1. Clean all air filters. A clogged air filter
can seriously affect the efficiency of the
blower and cause overheating and oil
usage.
2. Check relief valve to assure it is
operating properly.
1. Inspect the entire system for leaks.
2. Inspect condition of oil and change
if necessary.
3. Check drive belt tension and
tighten if necessary.
NOTE
Oil levels should be checked every 24 hours of operation.
Proper oil drain schedules require oil be changed before the contaminant load becomes so great that the
lubricating function of the oil is impaired or heavy disposition of suspended contaminants occurs. To check
the condition of the oil, drain a sampling into a clean container and check for the presence of water or solids.
Slight discoloration of the oil should not necessitate an oil change.
7.3 SPARE PARTS
Should adjustments or replacement eventually be needed, these can often be performed locally as
described in this book after obtaining required parts. Personnel should have a good background of
mechanical experience and be thoroughly familiar with the procedures outlined in this manual. Major
repairs not covered in this book should be referred to the nearest Tuthill Vacuum & Blower Systems service
representative.

Springfi eld, MO 65803-8702
NOTE
Current regulations require Material Safety Data Sheet to be completed and
forwarded to Tuthill Corporation on any unit being returned for any reason
which has been handling or involved with hazardous gases or materials.
This is for the protection of the employees of Tuthill Corporation who are
required to perform service on this equipment. Failure to do so will result
in service delays.
NOTE
When returning a blower to the factory for repair, under warranty, please
note the factory will not accept any unit that arrives without authorization.
Contact the Service Department for return authorization.
7.5 LONG TERM STORAGE
Any time the blower will be stored for an extended period of time, you should take make sure that it is
protected from corrosion by following these steps:
1. Spray the interior (lobes, housing and end plates) with rust preventative. This should be repeated as
conditions dictate and at least on a yearly basis.
2. Fill both end covers completely full of oil.
3. Firmly attach a very prominent tag stating that the end covers are full of oil and must be drained and
refi lled to proper levels prior to startup.
4. Apply a rust preventative grease to the drive shaft.
5. Spray all exposed surfaces, including the inlet and discharge fl anges, with rust preventative.
6. Seal inlet, discharge and vent openings. It is not recommended that the unit be set in place, piped to
the system, and allowed to remain idle for a prolonged amount of time. If any component is left open
to the atmosphere, the rust preventative will escape and lose its effectiveness.
7. During storage, ensure that the blower does not experience excessive vibration.
8. Attach a desiccant bag to either of the covers to prevent condensation from occurring inside the blower.
Make sure any desiccant bag (or bags) is so attached to the covers that they will be removed before
startup of the blower.
9. Store the blower in an air conditioned and heated building if at all possible. At least insure as dry
conditions as possible.
10. If possible, rotate the drive shaft by hand at least monthly in order to prevent seals from setting in one
position.

[51] with a beveled chisel and hammer.
23. Inspect all parts for wear and serviceability.
8.2 ASSEMBLY OF BLOWER
The assembly procedure is generally the same for all series, but where there are differences, notations are
made.
Gaskets are never used between rotor housing and end plates. Gaskets are used on 16/47 and 17/46
series between end covers and end plates to seal oil leakage. Dowel pins are used to locate end plates,
housing, and drive end cover in proper location relative to each other. Be sure they are in place.
It is recommended that the gear end rotor shaft bearings be purchased from Tuthill Vacuum & Blower
Systems, as they are specially ground to locate the rotors with correct end clearance relative to the gear
end plate.
8.2.1 PREPARATION OF END PLATES FOR ASSEMBLY
NOTE
Make sure all parts are clean and free of any nicks or burrs caused by
disassembly. Lip seal units will require all sleeves or seal journals to be
polished to remove any nicks or scratches. Failure to polish seal journals
1. 17/46, 57/81, 64/67 series blowers require labyrinth seals. Position labyrinth seals [51] with slots
pointing up and press one seal into each end plate bore.
2. 16/47, 17/46 series blowers utilize lip seals [12]. As means of sealing, apply a smooth coating of
Permatex #2 or silicone sealer to the O.D. edge of the seal shell. Press lip seal [12] into each end plate
bore, making sure the seal “lip” is facing up, or toward the oil. Apply grease to lip seals only.
3. 57/81, 64/67 series blowers require mechanical seals [54]. Apply smooth coating of silicone to the
O.D. of the seal shell as above. Position mechanical seal with the carbon face up and press the seal
[54] into each end plate bore, and into end plate bores. Wipe carbon with soft tissue and acetone or
similar cleaner, make sure seal is fully seated and shell is not deformed. Insure carbon is not scarred
or cracked. Mating rings will be seated later in the assembly procedure.
will result in seal leakage or damage. Refer to page 36 for information and
dimensions on seal pressing tools as well as other assembly tools required.
For 16/47 series, skip step 1 and proceed to step 2.

not use bearings that have not been fl ush ground to within a .001” (.025
mm) tolerance.
9. Install oil retainer [15] (4000 models only).
10. Install bearing retainer ring [14] and lock plates [61] on all series blowers. Bolts are item [62].
11. Check clearance between gear end plate and rotor lobe ends. Correct clearances are shown in the
Assembly Clearances table on page 34.
NOTE
Position of timing marks is for removing or installing driven gear. To remove
the drive gear, advance three teeth in the opposite direction.
12. Stand rotors [1] on arbor press with gear end shafts up and both keyways facing to the right. The drive
rotor should be on the left.
13. Install the gear end plate [4], making sure the feet are facing in the right direction, over the rotor shafts
and coming to rest on top of the rotor lobes. Be careful not to damage seals.
14. On 57/81/64/67 series, check lapped surface of seal mating ring to be sure it is perfectly clean. Use soft
tissue and cleaning agent (acetone) if necessary . Place a few drops of lubricating oil on its surface and
install on shaft with lapped surface coming to rest on top of carbon. Gently press with fi ngers to insure
compression is taking place and ring is not hung up for any reason.
15. Lubricate shafts and press the double row ball bearings [9] on rotor shafts and into end plate bores.
Secure with retainer rings [14] and screws [30].
NOTE
These bearings have been fl ush ground at the factory. The inner race will
have a black dot etched on the surface. This dot must be up and visible
when bearings are installed.
29
16. Check clearance between the face of the end plate and the rotor lobes. See exploded view for correct
gear and clearances. If clearances are not within specifi cations, recheck parts to fi nd cause of improper
clearances before proceeding.
17. Install spacer [17] (.260” [6.60 mm] thickness) and oil slinger [20] on the other shaft.
NOTE
Oil slinger and its spacer should always be mounted on either shaft for
18. Install timing shim in same location as found in disassembly. This does not necessarily insure the unit
will be in proper time. Adjustments can be made later in the assembly process.
19. Insert gear keys [24] into the rotor shaft keyways. Loose fi ts are not acceptable.
20. Lubricate shafts and install driver gear (right hand helix) on drive rotor (left side). To install driven gear,
align reference marks as shown in Figure 12 on page 29. Install driven gear carefully to avoid mashing
any teeth when engaging opposite gear.
21. Install washers [25] and fl at head allen screws [29].
22. Remove assembly from press and stand on work table with gears down. Place blocks under end plate
to prevent assembly from falling over. Drive gear should remain on left side.
23. On 57/81/64/67 series, use an RTV silicone type sealer. Place a small bead around periphery of the
end plate and encircling each bolt hole.
24. Install rotor housing [3] and secure with four screws evenly spaced.
25. Check clearances between end of lobes and housing using a fl at bar and feeler gauges or a depth
micrometer. Refer to exploded view for free end clearances.
vertical fl ow units.
8.2.3 FREE END ASSEMBLY
26. On 57/81/64/67 series put sealer on free end plate. (Same as step 15 above).
27. Install free end plate and secure with 4 screws.
28. On 57/81/64/67 series, repeat instructions given in step 7.
29. Install bearing spacers [123] (.025” [.06 mm] thickness) on each shaft (57/81/64/67 series only).
Lubricate shafts and tap on bearings [10]. Install spacers [67] on 57/81/64/67 series only.
30. Install oil retainer rings [14] with button head screws [30].
31. Install oil slinger [21] on lower rotor, (either shaft on vertical fl ow units) spacer [57] on opposite shaft,
washers [25], and screws [29].
30
8.2.4 ADJUSTING ROTOR INTERLOBE CLEARANCE
32. Lay the unit down with the drive gear
on the left. Using feeler gauges take
interlobe readings and record on
each side of housing as indicated
in Figure 14. By removing or adding
shim behind the helical gear, it rotates
as it is moved in or out and the driven
rotor turns with it, thus changing
the clearance between rotor lobes.
Changing the shim thickness .006’’
(.16 mm) will change the rotor lobe
clearance .003’’ (.08 mm) or one-half
the amount.
EXAMPLE: Referring to Figure 14,
check the clearance at AA (left hand
reading) and BB (right hand reading).
If AA reading is .003’’ (.08 mm) and
BB reading is .009’’ (.24 mm), by
removing .006’’ (.16 mm) of shim,
the readings will change one-half the
amount removed or .003’’ (.08 mm).
AA should then read .006’’ (.16 mm)
and BB should read .006’’ (.16 mm).
The fi nal reading should be within
.002’’ (.05 mm) of each other.

To determine the amount of shim to add or remove, subtract the small fi gure from the larger. If the
right side reading is higher than the left side, remove shim. If the right side reading is lower, add shim.
33. Install drive shaft [45] and secure with Allen screws [66]. Check drive shaft runout at seal journal. Do
not exceed .002’’ (.05 mm) T.I.R. Install lockwire [49].
34. Install bearing [9 or 50] on drive shaft and secure with retaining ring [47]. (Item 47 not required on 64/67
series.) Shield side of bearing must face outward (64/67 series only).
NOTE
To continue assembly for series 64/67, see “Special Instructions - 64/67
35. Remove temporary cap screws from each end plate and install cover gasket [28] and gear end cover
[6]. Make sure dowel pins [22] are in place. Sealer is not required on factory supplied gaskets. Secure
with cap screws [26A] and washers [27].
