Table 3 — Fan Performance — 48AJ,AK020,025 and 48A2,A3020 Units
Table 4 — Fan Performance — 48AJ,AK027,030 and 48A2,A3025-030 Units
LEGEND
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:
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.
