(17½ Ton)
Standard Efficiency
For Standard Evaporator Fan Speed (RPM), reference Table PD-31.
For Oversize Evaporator Fan Speed (RPM), reference Table PD-33.
For Standard Motor and Low Static Drive, reference Table PD-34.
Fan motor heat (MBH) = 3.15 x Fan Bhp.
Data includes pressure Drop Due to West Coils and Filters.
No accessories or options are included in pressure drop data.
Refer to Table PD-36 to determine add’l static pressure drop due to other options/accessories
Notes:
1. For 380V/60 Hz units, the oversized motor is used as the standard motor, Refer to “Motor and
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.
