Table 17 — Fan Performance — 48A4,A5,A8,A9035 Units
Table 18 — Fan Performance — 48A4,A5,A8,A9040 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 and Humidi-MiZer operation.
