Table 31 — Fan Performance, 48EW,EY054-068 — Horizontal Discharge Units
LEGEND
Bhp — Brake Horsepower
NOTES:
1. Fan performance is based on dry 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 in the
cooling mode. Performance 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.
