Permanent split capacitor (PS) motors are of the three speed type with separate taps (High, Medium and Low) which provide variable horsepower outputs. ommonly, units are selected and sized on a conservative basis and actual airflow and/or external static pressure requirements are lower than specified. When this is the case, the unit fan motor can be run at low or medium speed, reducing power consumption and operating cost. 2. All fan curves shown are for 2 volt single phase, -speed PS motors and include internal losses for cabinet, electric heater and or 4 row water coil.. For other coil combinations and filters, adjust performance curves based on pressure losses or use Selectworks. 4. Filter pressure drops table shown on page 2. 5
