Units With Airfoil Fan*
LEGEND
*If calculating static pressure for a 48 Series unit, be sure to add gas
heat pressure drop from Table 30C.
NOTES:
1. Fan performance is based on wet coils and clean 2-in. filters.
2. For return fan (48Z6,Z8 and 50Z6,Z7,Z8,Z9) high-capacity power
exhaust (48ZT,ZW and 50ZT,ZW,ZX,ZZ) units, add component
pressure drop for economizer. Do not add component pressure
drop for power exhaust.
3. See Table 30C before using Fan Performance tables.
4. Conversion — Bhp to kW:
See Tables 26-28 for motor efficiency.
