Chemglass CG-2025 - Manual (Page 3)

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 manufacturer’s 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.
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
WARNING
Injury Hazard
Air stream from product may contain solid or liquid
material that can result in eye or skin damage.
Do Not use combustible gases to drive this motor.
Wear hearing protection. Sound level from motor
may exceed 85 db (A).
Failure to follow these instructions can result in eye
injury or other serious injury.
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.
