Table 25 — Fan Performance — 50A4,A5,A8,A9050 Units
Table 26 — Fan Performance — 50A4,A5,A8,A9060 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.
