Bhp Ð Brake Horsepower

NOTES:

1.Fan performance is based on wet coils, economizer, roof curb, cabinet losses, and clean 2-in. ®lters.

2.Conversion Ð Bhp to watts:

Bhp x 746

Watts =

Motor efficiency

3.Variable Air Volume units will operate down to 70 cfm/ton. Per- formance at 70 cfm/ton is limited to unloaded operation and may be additionally limited by edb (entering dry bulb) and ewb (enter- ing wet bulb) conditions.
