LEGEND
Bhp — Brake Horsepower
NOTES:
1.Fan performance is based on wet coils, economizer, roof curb, cabinet losses, and clean
2.Conversion — Bhp to watts:
Watts =
Bhp x 746
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 (entering wet bulb) conditions.
