For Standard Evaporator Fan Speed (RPM), reference Table 50.
For Standard Motor & Low Static Drive Accessory Fan Speed
(RPM), reference Table 51.
For Oversized Evaporator Fan Speed (RPM), reference Table 53.
Fan motor heat (MBH) = 3.15 x Fan BHP.
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 54 to determine additional static pressure
drop due to other options/accessories.
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.
*For 5000, 6500, 7000 and 7500 CFM, unit applications below 320
CFM/Ton are only applicable to TCD models only (No Gas
Heat). See below for restrictions.
• Electric heaters restricted on applications below 320 CFM/Ton.
• Dehumidification (Hot Gas Reheat) or TXV with Frostat and
Crankcase Heaters are required on applications below 320
CFM/Ton.
