Table 23 — Fan Performance — 50A4,A5035 Units
Table 24 — Fan Performance — 50A4,A5040 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 additional limited by edb
and ewb conditions and Humidi-MiZer operation.
