Notes:
1. Data includes pressure drop due to wet coil and 2" filter.
2. Fan motor heat (MBh) = 3.15 x BHP.
3. 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.
