For Standard Evaporator Fan Speed (RPM), reference Table PD-86.
Notes
Data includes pressure drop due to standard filters and wet coils.
No accessories or options are included in pressure drop data.
Refer to Table PD-89 to determine additional static pressure drop due to other options/accessories
2-HP Fan Motor Heat (MBH) = 2.000 x Fan BHP+.5000.
3-HP Fan Motor Heat (MBH) = 2.900 x Fan BHP+.4750.
1. Field Supplied Motor Sheave 1VL40L x 7/8 and Fan Sheave AK71 required.
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.
