Brake Horsepower
NOTES:
1. Fan performance is based on wet coils, economizer, roof curb, cabinet
losses, and clean 2-in. filters.
2. Conversion — Bhp to watts:
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 additionally limited
by edb and ewb conditions.
