Connection
7. Check the direction of the motor airflow. A single rotation
motor will operate properly only in one direction. Single
rotation motors require a sound absorber to be connected
to the air port. Remove the plastic shipping plugs from the
ports. Save plugs for future use during shutdown.
8. Install a 5-micron filter in the air line before the connec-
tion to the motor. Next install an air pressure regulator to
control motor speed and torque.
9. Install a moisture trap and filter in the air line ahead of
motor (Graymills Part No. FRL-2). Use a 1/4” air line for
efficiency of output and control of speed.
10 .An automatic air line lubricator should be installed in the air
line as close as possible and no more than 18 inches (1/2
meter) from the air motor. Install the lubricator level with or
above the air motor so that the oil mist will blow directly
into or fall down into the motor.
11. Fill the oil reservoir to the proper level with SAE 10W high
detergent or non-detergent motor oil. Adjust inline oiler to
feed 1 drop of oil per minute for high speed or continu-
ous duty usage. DO NOt overfeed oil or exhaust air may
become contaminated.
Check intake and exhaust filters after first 500 hours of
operation. Clean filters and determine how frequently filters
should be checked during future operation. This one proce-
dure will help assure the motor’s performance and service
life.
12. Clean the compressed air connection with low pressure air
to remove any dirt from the line before connecting to the ports.
Use the proper sized air supply. For the most efficient output
and control of speed, use air lines that are the same size
as the motor inlet port if the connection is less than 7 feet
(2 meters). For longer connections, use the next pipe size
larger than the motor intake port.
Air Consumption
13. Check all connections before starting motor. It is your
responsibility to operate this product at recommended
speeds, loads and ambient room temperatures.
Do not run the motor at high speeds with no load. This will
result in excessive internal heat that may cause motor damage.
The starting torque is less than the running torque. The
starting torque will vary depending upon the position of the
vanes when stopped in relation to the air intake port.
Rotate air inlet ball valve slowly until desired speed is
obtained.
14. Use a pressure regulator (FRL-1 #2 air motor, FRL-2 for #1
air motor) and the supplied valve to regulate the motor’s
speed and torque. This will provide the required power and
will conserve air. Rotate air inlet ball valve slowly. Open
the air supply valve to the motor. Set the pressure or flow
rate to the required speed or torque. Adjust the lubricator
to feed one drop of oil for every 50-75 CFM (1.5-2 M3
per minute) of air moving through motor. Check the oil level
daily. The gear reducer does not need lubrication.
MAINTENANCE
Wear eye protection when flushing this product.
Disconnect air supply and vent all air lines and muffler.
Air stream from product may contain solid or liquid material
that can result in eye or skin damage.
Flush this product in a well ventilated area.
Use any nontoxic, nonflammable industrial cleaning solvent.
DO NOT use kerosene or other combustible solvents to flush
this product.
Failure to follow these instructions can result in eye injury or
other serious injury.
It is your responsibility to regularly inspect and make necessary
repairs to this product in order to maintain proper operation.
Lubrication
Use a detergent SAE #10 automotive engine oil for lubricating.
Lubricating is necessary to prevent rust on all moving parts.
Excessive moisture in air line may cause rust or ice to form in
the muffler when air expands as it passes through the motor.
Install a moisture separator in the air line and an after cooler
between compressor and air receiver to help prevent moisture
problems.
Manual Lubrication (if necessary)
Shut the air motor down and oil after every 8 hours of
operation. Add 10-20 drops of oil to the air motor intake port.
Automatic Lubrication
Check intake and exhaust filters after first 500 hours of
operation. Clean filters and determine how frequently filters
should be checked during future operation. This one procedure
will help assure the motor’s performance and service life. See
#11 on page 3 for filling instructions.
Flushing
Flushing this product to remove excessive dirt, foreign particles,
moisture or oil that occurs in the operating environment will
help to maintain proper vane performance. Flush the motor if it
is operating slowly or inefficiently.
Check the direction of the motor airflow. A single
rotation motor will operate properly only in one direction.
Single rotation motors require a sound absorber to be
connected to the air port. Remove the plastic shipping
plugs from the ports. Save plugs for future use during
shutdown.

Install a 5-micron filter in the air line before the
connection to the motor. Next install an air pressure
regulator to control motor speed and torque.
Use the proper sized fasteners. For the most efficient
output and control of speed, use air lines that are the
same size as the motor inlet port if the connection is
less than 7 feet (2 meters). For longer connections, use
the next pipe size larger than the motor intake port.
Connect lines to motor in the proper direction.
A reversible motor will work equally well in both
directions. Connect a 4-way valve with piping to both
air ports of motor to make reversing possible. Connect
the sound absorber on the exhaust air port or valve
connection.
Do not add any thrust to the end or side of the shaft
when making connections.
Lubricating the drive shaft will make assembly
easier. Use a puller for removal of pulleys,
couplings and pinions on the motor shaft.
Check that the tension on the belt pulley matches the
manufacturerʼs specifications. Do not exceed the
maximum radial and axial forces on the shaft. If the
motor shaft is connected to the part to be driven without
a coupling, check that the radial offset and axial force
effect will not cause problems.
Do not use a hammer on the shaft or
connections.
Use only belts with < 10 9 electrical leakage
resistance to prevent static electrical problems.
Ground the motor.
Accessories
A muffler is shipped with the air motor (except 16AM)
but is not installed. Consult your Gast
Distributor/Representative for additional filter
recommendations. Install a moisture trap and 5 micron
filter in the air line ahead of motor.
Check all connections before starting motor. It is your
responsibility to operate this product at recommended
speeds, loads and room ambient temperatures. Do not
run the motor at high speeds with no load. This will
result in excessive internal heat that may cause motor
damage.
OPERATION
Air consumption data at various speeds and pressures
are available from your Gast Distributor/Representative
or the factory.
The starting torque is less than the running torque. The
starting torque will vary depending upon the position of
the vanes when stopped in relation to the air intake
port.
Mounting
This product can be installed in any orientation. Mount
the motor to a solid metal base plate that is mounted to
a stable, rigid operating surface. Use shock mounts to
reduce noise and vibration. Install a pressure regulator
or simple shut-off valve to control motor.
Fill the oil reservoir to the proper level with Gast
#AD220 or SAE 10W high detergent or non-detergent
motor oil. For food processing applications, White Rex
425 food grade motor oil is FDA approved. Adjust
lubricator to feed 1 drop of oil for every 50 CFM of air
while the unit is running, or 1 drop of oil per continuous
minute of run time. Do Not overfeed oil or exhaust air
may become contaminated.
Clean the compressed air connection with low pressure
air to remove any dirt from the line before connecting to
the ports.
Connection
An automatic air line lubricator should be installed in the
air line as close as possible and no more than 18
inches (1/2 meter) from the air motor. Install the
lubricator level with or above the air motor so that the oil
mist will blow directly into or fall down into the motor.
Use a pressure regulator and/or simple shut-off valve to
regulate the motor’s speed and torque. This will provide
the required power and will conserve air. Open the air
supply valve to the motor. Set the pressure or flow rate
to the required speed or torque. Adjust the lubricator to
feed one drop of oil for every 50-75 CFM (1.5-2 M 3 per
minute) of air moving through motor. Check the oil level
daily. The gear reducer does not need lubrication.
