High Efficiency
*Indicates both downflow and horizontal units.
For Standard Evaporator Fan Speed (RPM), reference Table PD-31.
For Standard Motor & High Static Drive Accessory Fan Speed (RPM),
reference Table PD-32.
For Standard Motor & Low Static Drive Accessory Fan Speed (RPM),
reference Table PD-34.
Fan motor heat (MBH) = 3.15 x Fan BHP
*Unit applications below 8000 CFM
• Electric heaters restricted on applications below 8000
CFM.
• Dehumidification (Hot Gas Reheat) or TXV with Frostat
and Crankcase Heaters are required on applications
below 8000 CFM.
Notes:
Data includes pressure drop due to wet coils and filters.
No accessories or options are included in pressure drop data.
Refer to Table PD-35 to determine add’l 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.
