Above specifications are based on 80 to 125 psig operating pressures. Maximum pressure drop is less than 3 psi.
11.2 TABLE 2 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 per minute for every
50 cfm of air passing through the air motor.
3. Drip rate is the recommended drops of oil that enters the air motor per minute based on the CFM.
Two types of lubricators have been used in Schmidt® AirPrep Systems. Current production units
are equipped with “oil-fog” lubricators (Style MP). Systems manufactured prior to September 2016
are equipped with “micro-fog” lubricators (Style L74M). Note: Micro-fog lubricator drip rates are
significantly higher because only a fraction of the drip total enters the air stream.
