7.5 HP Standard Motor & High Static Drive Accessory
For Standard Evaporator Fan Speed (RPM), reference Table PD-31.
For Standard Motor & High Static Drive Accessory Fan Speed (RPM), reference Table PD-32.
For Standard Motor & Low Static Drive Accessory Fan Speed (RPM), reference Table PD-34.
Fan motor heat (MBH) = 3.15 x Fan BHP
Data includes pressure drop due to wet coils and filters.
No accessories or options are included in pressure drop
data. Refer to Table PD-35 to determine add’l static pressure drop due to other options/accessories.
Note:
1. For 380V/60 Hz units, the oversized motor is used as the standard motor. Refer to “Motor & Sheave/Fan
Speed” tables to determine operating range.
Factory supplied motors, in commercial equipment, are
definite purpose motors, specifically designed and tested
to operate reliably and continuously at all cataloged
conditions. Using the full horsepower range of our fan
motors as shown in our tabular data will not result in
nuisance tripping or premature motor failure. Our
product’s warranty will not be affected.
*Indicates both downflow and horizontal units.
