Table 27 — Fan Performance, 48EJ,EK024,034 — Vertical Discharge Units
(For EW,EY units, reduce net available external static pressure by 0.3 in. wg)
LEGEND
Bhp — 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. 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.
