Sept/20
The air supply must be clean (i.e. filtered)
Large contaminants in the air supply will clog the screens in the
PowerHandling air valve and at the inlet to the air motor. This
will reduce the air volume delivered to the vanes and result in
reduced torque and speed. Small contaminants in the air
supply will pass through these screens and enter the vanes and
cylinder of the air motor. Some will be immediately exhausted
but others will remain, causing damage and premature wear of
the vanes, bearings and seals along with diminished torque and
speed. If not addressed, the scarring of the inside of the
chamber will require honing of the cylinder or replacement of
the entire motor.
The air supply must be dry (i.e. inline water
traps installed)
Moisture in the compressed air supply will result in corrosion
inside the air motor’s vanes and precipitate the need for
replacement of the vane kit. The effect of moisture will be
diminished torque and speed and ultimately motor failure. A
quick way to check if there is moisture in the air lines is to
remove the muffler and look for moisture and or expelled
corrosion in the muffler.
Lubrication to be provided to the air motor
To maximize the life of your air motor the air supply should be
“continuous oil lubricated”. If this is not available, daily
insertion of a few drops of oil into the air line should be
included in the maintenance procedures of the plant. The
planetary gearbox (gear-sets and bearings) are a sealed unit
and typically will not require any maintenance for the life of
the machine. However, if while maintaining the motor it is
observed the gearbox is not fully packed with grease, please
contact your PowerHandling representative for details on the best course of action.
