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.
