  • Vane Life: Depends upon speed, operating pressure and motor
  • Operating Pressure: 100 psi or below (7 bar)

Correct installation is your responsibility. Make sure you have the proper installation conditions and that the specified installation clearances are available.



Check the direction of the motor airflow. A single rotation motor will operate properly only in one direction. Install a filter in the air line before the connection to the motor. Connect lines to motor in the proper direction. A reversible motor will work equally well in both directions. Connecting a 4-way valve with piping to both air ports of the motor will make reversing possible.

Do not add any thrust to the end or side of the shaft when making connections. Do not use a hammer on the shaft or connections.


This product can be installed in any orientation. Mount the motor to a solid base plate that is mounted to a stable, rigid operating surface. Install a pressure regulator or simple shut- off valve to control motor.

Consult your Fawcett Co. representative for additional filter recommendations. Install a moisture trap and filter in the air line ahead of the motor. For the most efficient output and control of speed, use air lines that are the same size or the next pipe size larger than the motor intake port. An automatic air line lubricator should be installed 18” or as close as possible in the air line just ahead of the motor.

Adjust the lubricator to feed one drop of oil for every 50-75 CFM of air moving through the motor. Air consumption at various speeds and pressures are available from your local Fawcett representative.

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.

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. 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.


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 85db(A). Failure to follow these instructions can result in burns, eye injury or other serious injury.

Air Power:

Check to ensure the air valve is in the closed position, then connect air supply. Check rotation to be sure the mixer shaft is rotating in a clockwise direction, looking downward into the container.

Once the mixer is in the container, it is now safe to operate.


• Never run mixer without an Impeller.
• Never run the impeller in open air.
• Never run impeller outside a container.


Injury Hazard

Disconnect air supply and vent all airlines. Wear eye protection when flushing this product. 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. Do not use kerosene or other combustible solvents to flush this product. Failure to follow these instructions can result in burns, 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.

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 product’s performance and service life.


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.

Use only #AH255B Flushing Solvent. DO NOT use kerosene or ANY other combustible solvents to flush this product.


Use only #AD220 or a detergent SAE #10 automotive engine oil for lubricating. Lubricating is necessary to prevent rust on all moving parts. Excessive moisture in the 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.

Automatic Lubrication

Adjust inline oiler to feed 1 drop of oil per minute for high speed or continuous duty usage. Do not overfeed oil or exhaust air may become contaminated.
1. Disconnect air line and muffler.
2. Add flushing solvent directly into motor. If using liquid solvent, pour several tablespoons directly into the intake port. If using #AH255B, spray solvent for 5-10 seconds into intake port.
3. Rotate the shaft by hand in both directions for a few minutes.
4. You must wear eye protection for this step. Cover exhaust with a cloth and reconnect the air line. Slowly apply pressure until there is no trace of solvent in the exhaust air.
5. Listen for changes in the sound of the motor. If motor sounds smooth, you are finished. If motor does not sound like it is running smoothly, installing a service kit will be required. (See “Service Kit Installation”).
Check that all external accessories such as relief valves or gauges are attached and are not damaged before operating product.


It is your responsibility to follow proper shutdown procedures to prevent product damage.
1. Turn off air intake supply.
2. Disconnect plumbing.
3. Remove air motor from connected machinery.
4. Wear eye protection. Keep away from air stream. Use clean, dry air to remove condensation.
5. Lubricate motor with a small amount of oil in chamber. Rotate shaft by hand several times.
6. Plug or cap each port.
7. Coat output shaft with oil or grease.
8. Store motor in a dry environment.
