INSTALLATION
Correct installation is your responsibility. Make sure
you have the proper installation conditions and that
installation clearances do not block air flow.
Blocking air flow over the product in any way can
cause the product to overheat.
The blower must be installed with the properly sized
inlet filter, gauge and relief valve to protect the
product from dirt and over-heating.
be killed or seriously injured if you don’t
Remove plugs from the IN and OUT ports. Use a small
amount of pipe thread lubricant when connecting
plumbing to protect the aluminum blower threads.
Connect with pipe and fittings that are the same size or
larger than the productʼs threaded ports. When
installing two blowers in parallel, use plumbing that is
two whole pipe sizes larger in diameter than that of the
blower. Be sure to connect the intake and exhaust
plumbing to the correct inlet and outlet ports.

P
Accessories
Install two vacuum gauges, one before and one after
filter, to monitor restriction through filters. As filters
become clogged, performance efficiency will be
reduced. Filters should be checked periodically and
replaced when necessary. See pages 6, 7 and 8 for
installation.
Install a relief valve to avoid changes in pressure or
vacuum that can cause overloading of large blowers.
Install an intake filter with a relief valve to prevent
foreign material from entering blower if blower is used in
a vacuum application in a dirty environment. In
applications where there is high humidity or liquids
being used in the process, install a moisture separator.
See Recommended Accessories on pages 7-9 or
consult your Gast Distributor/Representative for
additional filter and accessories recommendations. Do
Not install check valves that close with a strong spring.
The recommended check valves (page 7) provide
minimal pressure drop, positive sealing and are
resistant to the high discharge temperatures of large
blowers.
Electrical Connection
Mounting
The single impeller blower should be oriented with the
shaft in a horizontal position, unless the modelʼs product
features state otherwise. Mounting the product to a
stable, rigid operating surface and using shock mounts will
reduce noise and vibration. Make sure that appropriate
noise dampening media is used with respect to the
working media for the application.
Rotation
From the drive side of the blower, check that the blower is
rotating clockwise. (he drive side is marked with an arrow
on most models.) Proper rotation can also be checked by
the air flow at the IN and OUT ports.
Plumbing
Remove any foreign material (burrs, chips, welding
drops, slag, pipe cuttings, excess sealant, sand or
lime)
Check rotation before connecting to plumbing. Inlet
and outlet ports are not designed to support plumbing.
WARNING
If working media other than standard atmosphere
is to be pumped through unit, consult factory for
acceptable parameters. Severe personal injury may
occur if hazard is ignored.
CAUTION:
Never lubricate this oil-less blower. The sealed
bearings are grease packed. All of the wetted
components are made with corrosion resistant
material and with paper filtration. The unit should
last for years.
Internal wetted components are either stainless
steel or coated for corrosion resistance. The blower
is sealed with a shaft seal and impregnated castings
to prevent working fluid leakage during operation.

OPERATION
Injury Hazard
Install proper safety guards as needed to prevent
a
ny close contact with blower suction area.
Keep fingers and objects away from openings and
rotating parts.
Product surfaces become very hot during operation,
allow product surfaces to cool before handling.
Air stream from product may contain solid or liquid
m
aterial that can result in eye or skin damage,
wear proper eye protection.
Wear hearing protection. Sound level from some
models may exceed 85 dBA.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
Electrical Shock Hazard
Disconnect electrical power supply cord to drive
motor before performing maintenance on this
product.
Some motors are thermally protected and will
automatically re-start when protector resets.
If product is hard wired into system, disconnect
electrical power at the circuit breaker or fuse box
before performing maintenance on this product.
Failure to follow these instructions can result in
death, fire or electrical shock.

WARNING
Injury Hazard
Product surfaces become very hot during operation,
allow product surfaces to cool before handling.
Air stream from product may contain solid or liquid
material that can result in eye or skin damage,
wear proper eye protection.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
It is your responsibility to operate this product at
recommended pressures or vacuum duties and
room ambient temperatures.. Do not throttle
discharge or suction pipe to reducer capacity.
Throttle will increase differential pressure causing
increasing power absorption and working
temperatures.
Start Up
Operate blower for an hour and then check:
1. Ambient temperature – Check room and
discharge air temperatures. Increased room
temperatures may require stronger ventilation
especially for larger blowers. Exhaust air
should not exceed 215ºF (102ºC) for all
blowers less than 3.5 Hp. Exhaust air should
not exceed 275ºF (135ºC) for all blowers
above 3.5 Hp.
2. Working pressure and vacuum values – Adjust
relief valve pressure or vacuum setting, if
needed.
WARNING
Power must be de-energized and disconnected
from the drive motor before servicing. Be sure all
rotating parts have stopped, electrical shock or
severe cuts can result if hazard is ignored.
It is your responsibility to regularly inspect and
make necessary repairs to this product in order to
maintain proper operation. Make sure that pressure
and vacuum is released from product before
starting maintenance.
The separate drive electric motor and blower need
periodic cleaning to remove accumulated dust and dirt.
If they are not cleaned, this can result in excessive
vibration, an increase in temperature or can reduce the
service life of the system.
MAINTENANCE
Check filter elements and clean motor and blower after
first 500 hours of operation. Replace filter elements.
This one procedure will help assure the productʼs
performance and service life.
An increase in the differential pressure across an inlet
filter indicates its getting clogged. Clean the inlet air
filter as often as needed, blowing down against the
current to clean it. A dirty filter cartridge causes a high
intake resistance resulting in an increase of differential
pressure, absorbed power and working temperature.
Failure to clean replace these filters will result in
excessive pressure drop, a reduction in system air flow
and the blower will run hotter.

tension in new drives or those in service.
CAUTION:
Do not over tighten belt as it will cause
misalignment and could lead to premature failure.
Gates “Poly Chain” Belt Tensioning Requirements
Belt Tensioning and Alignment (cont.)
We strongly suggest using a Gates Poly Chain Drive. It
has been properly engineered for this type of application.
If you choose to use a “V” belt drive, the sheave on the
blower must be less than 4” in outside diameter. This
sheave should be mounted on the shaft such that it will
not block air from entering the blower cooling fan (we
recommend this high speed belt drive be engineered
following the belt drive manufacturers recommendations).
To avoid annoying vibration and noise, both sheaves
should be dynamically balanced and fit snugly on the
shaft.
