Data
For Standard Evaporator Fan Speed (RPM), reference Table PD-56.
Table includes Dehumidification (Hot Gas Reheat Option).
*Unit applications below 2400 CFM
• Electric heaters restricted on applications below 2400 CFM.
• Dehumidification (Hot Gas Reheat) or TXV with Frostat and Crankcase Heaters are required on applications below 2400 CFM.
Notes:
Data includes pressure drop due to standard filters and wet coils.
Data does not include pressure drop due to reheat coil.
No accessories or options are included in pressure drop data.
Refer to Table PD-61 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

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.
