AFTERCOOLER ELECTRIC MOTOR, AIR MOTOR & FAN DATA
ELECTRIC MOTOR
AIR MOTOR
All motors shown are TEFC. Published electrical ratings are approximate, and may vary because of motor brand. Actual
ratings are on motor nameplate. Fan motors
must not
be cycled. Outdoor applications must be protected from direct weather.
If ductwork or additional static resistance is added to the cooler air stream, an auxiliary air mover may be required.
1. Air inlet to the air motor must be regulated to this pressure.
2. CFM (Free Air) consumption of the air motor. Lubrication = One drop of oil for every 50-75 cfm of air passing through the
air motor.
