Data includes pressure drop due to filters and wet coil.
Fan motor heat (MBH) = 3.53 x Fan Bhp.
Trane’s 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. Field supplied Browning fan sheave AL74 and Belt A48 required.
2. Field supplied Browning motor sheave IVL34 and Belt A48 required.
