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 performance is with 12x11 FC Centrifugal blower wheel.
3. YSC060AK* uses a 1.0 hp direct drive motor and 12x11 FC Centrifugal blower wheel. Refer to oversized motor column for the standard motor performance data.
