Bhp -- Brake Horsepower
edb -- Entering Dry Bulb
ewb -- Entering Wet Bulb
NOTES:
1. Fan performance is based on wet coils economizer roof curb, cabinet losses and clean
2-in. filters.
2. Conversion -- Bhp to watts:
Watts = Bhp x 746
Motor efficiency
3. Variable air volume units will operate down to 70 cfm/ton. Performance at 70 cfm/ton is
limited to unloaded operation and may be additional limited by edb and ewb conditions.
