CONGRATULATIONS on the purchase of a new Tuthill Transport Blower. Please examine the blower for shipping damage, and if any damage is found, report it immediately to the carrier. If the blower is to be installed at a later date, make sure it is stored in a clean, dry location and rotated monthly. Make sure covers are kept on all openings. If the blower is stored outdoors, be sure to protect it from weather and corrosion.

Tuthill Transport Blowers are built to exacting standards and, if properly installed and maintained, will provide many years of reliable service. Read and follow every step of these instructions when installing and maintaining the blower.

OTE: N Record the blower model and serial

numbers of the machine in the OPERATING DATA form on the inside back cover of this manual. Use this

identication on any replacement part orders, or if service or application

assistance is required.

Installation

T855 / T1055 VENT HOLES

OTE: N Due to multiple bracket congurations

that are used by installers across the country our T855 and T1055 blowers have 1/8" threaded NPT vent holes. Vent plugs are not supplied with the blower.

If you choose to place plugs into vent holes to keep foreign matter out of the units, you can purchase HK 1/8-27 NPTF 7/8 Taper Flush Socket Pressure Plug part # 1181142 from Fastenal or similar style plugs from your local auto parts store. Another option, depending on mounting bracket space, is

to use 90° elbows with or without exible tubing.

If you choose to use vent plugs, then follow the subsequent instructions. The exact plug location will vary based on the mounting position.

The image below shows one option for the vent

hole locations on a horizontal airow mount.

CAUTION

Never plug all the vent holes or serious damage to seals and bearings will result. Four vent holes (two per side or all four on one side) must always be open.

Figure 3-3 – Alternate plug conﬁguration: Horizontal mount with holes plugged on the bracket side

Figure 3-2 – Mounting Conﬁguration

In this mounting conguration (See Figure 3-2) the four holes (two are shown and two are on the opposite side top) could have plugs added to them. This would leave the four holes on the bottom of the unit open or 90° 1/8" NPT elbows that face down.

Four vent holes should always be open to air. You can plug all the holes on the bracket side, then use four 90° elbows on the non-bracket side (horizontal mount). Or you can plug two on each end plate at the top side and leave two on each end plate at the bottom open.

Figure 3-4 – Alternate plug conﬁguration: Horizontal mount with street elbows

Operator’s Manual 2023 Rev C p/n 2023

PTO SELECTION FOR

Installation

TRANSMISSION

Blower speed and pressure require adequate horsepower and torque. See Performance Curves on page 12.

Engine speed and blower speed require the adequate ratio PTO be installed for proper blower operation.

ENGINE SPEED

Keep engine speed constant when the blower is in the operating cycle. Install a constant-speed governor or throttle control system to ensure proper blower operation.

PRESSURE RELIEF VALVE

Size the pressure relief valve for the correct air ow

and pressure rating. Install the valve as close to the blower as possible and before the check valve.

An undersized air lter will cause the blower

to operate at higher temperatures. This can cause blower to overheat, causing irreparable damage.

SUCTION AND DISCHARGE PIPING

All piping should be free and clear of any welding slag or foreign material.

The suction piping requirement is a minimum of

5 in. (127 mm) diameter for proper ow to the

blower.

Discharge piping is a minimum of 4 in. (102 mm) diameter.

Do not use a rubber elbow in the suction line during vacuum operation. The elbow will fail causing the blower to overheat. This will cause damage to the blower.

Ensure that pipe compound is used on the threads of the male end of the relief valve to seal against air leakage.

An undersized or improperly set relief valve will cause the blower to operate at higher temperatures. This can cause the blower to overheat, causing irreparable damage.

AIR FILTER

Select a lter suitable for the air ow requirement of the application. Use air lters on food and plastic

products to prevent contamination.

MOUNTING BRACKET

To reduce stress on the blower housing, be sure to properly mount the blower with the correct bracket.

CHECK VALVE

Minimum restriction for application. Mount downstream of the relief valve. Size the valve for

maximum air ow (CFM or m³/hr).

MUFFLERS AND DISCHARGE FILTRATION

Minimum restriction for application. Mount downstream of the relief valve.

Operator’s Manual 2023 Rev C p/n 2023

Installation

VACUUM VALVE

Size for proper air ow and vacuum rating.

This valve should be located before the blower

inlet lter. This valve is normally mounted on the

trailer.

To properly protect the blower from overheating when vacuum loading, install a vacuum valve.

LUBRICATION

Every Tuthill blower is factory-tested, oil-drained, and shipped dry. Fill both oil reservoirs to the proper level before operation.

Every Tuthill Transport Blower is supplied with four 1-quart containers of Tuthill PneuLube™ ISO 100

synthetic oil. Before lling the blower, check Table 3-2 to conrm the amount of oil required.

For applications requiring food-grade lubricant, use only Tuthill PneuLube FG synthetic oil.

OTE: N If installing a Tuthill Transport Blower

for vertical air ow (optional), additional

oil than what is included with the blower will be needed for installation. Tuthill PneuLube is available from your authorized Tuthill Transport Blower Distributor.

Filling Procedure

To ensure the proper oil level, always use this lling

procedure:

1. Remove the ll plugs from both gear end and drive end plates.

2. Slowly pour oil through ll until oil appears in the oil sight glass. Bring the oil level to the center of the sight glass.

CAUTION

Do not start the blower until you are certain that oil is in BOTH ends of the blower. Check BOTH sight glasses to ensure that oil levels are correct before starting. Operation of the blower without proper lubrication will cause the blower to fail and void its warranty.

WARNING

NEVER ATTEMPT TO CHANGE OIL WHILE THE BLOWER IS IN OPERATION. Failure to heed this warning will result in damage to equipment and/or serious personal injury. Oil level must be checked while the blower is not running and truck is parked on a level surface.

SHUR-MELT™ Thermal Relief Plugs

All T855 and T1055 blowers are equipped with two patented thermal relief plugs. Upon temperature activation, the plugs will relieve 5 to 6 PSIG to protect the blower from damage. When replacing these plugs, you must ensure that a plug is installed on each end of the blower for complete protection.

3. Verify the oil level is at the proper level in both the gear end and drive end sight glasses.

4. Replace the ll plugs that were removed in step 1.

Never mix oil types or grades in a Tuthill Transport Blower. Mixing lubricants in the blower will result in gear and bearing failure.

OPERATION

1. Inspect the blower mounting, drive line, PTO,

and air lter for damage.

2. Remove the Camlock dust cap and connect the hot air hose.

3. Follow the trailer instructions regarding product hose connection and valve operation.

4. Slowly engage PTO with the engine at idle, bring it up to operating speed, and lock the engine at the recommended speed (shown in the cab).

5. Unload the trailer as per trailer manufacturer’s recommendation. Do not exceed the maximum tank pressure.

6. While discharging, visually check the blower

for vibration, mechanical noise or excessive

heat.

7. If the relief valve is opening, adjust the proportioning valve to reduce the tank pressure.

OPERATION

WARNING

The blower and accessories will become hot enough to cause serious skin burns on contact.

Rotating machinery is dangerous.

Always wear ear protection when near an operating blower.

Do not run at slower RPM to cool unit down. Slower RPM will produce heat.

8. Reduce pressure to zero as per the trailer

manufacturer’s instructions.

9. Disengage PTO. No cool-down period is required.

10. Disconnect the blower hose and replace the Camlock dust cap.

Operator’s Manual 2023 Rev C p/n 2023

REGULAR MAINTENANCE

A well-designed maintenance program will add years of service to the blower.

Check a newly installed blower frequently during

the rst month of operation, especially lubrication.

Check the oil level and add oil as needed.

Complete oil changes are recommended annually,

or more frequently depending on the operating conditions. The following is recommended as a minimum maintenance program. An oil analysis program is recommended.
