Fan motor heat (MBH) = 3.72 x Fan Bhp + .24.
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.
Notes:
1. Data includes pressure drop due to wet coil and filters.
2. 5 Ton oversized motor peformance is with 12 x 11 FC Centrifugal blower fan.
