NOTES:
Data includes pressure drop due to standard filters and wet coils.
No accessories or options are included in pressure drop data.
Refer to Table PD-54 to determine additional static pressure drop due to other options/accessories
Fan Motor Heat (MBH) = 2.829 x Fan BHP+.4024.
1. Field Supplied Fan Sheave AK61 required. Field Supplied Belt may be necessary.
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.
