Notes:
Fan motor heat (MBH) = 3.15 x Fan BHP.
Data includes pressure drop due to wet coils and filters.
No accessories or options are included in pressure drop data.
Refer to Table PD-13 to determine add’l static pressure drop due to other options/accessories.
Notes:
1. Field supplied fan sheave BK115 required. Field supplied belt may be necessary.
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 tabulated data will not result in nuisance tripping or premature motor failure. Our product's warranty will not be affected.
