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 Fan Sheave AK79 and Belt AX38 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.
