Table 22 — Fan Performance — 48ZG,ZN,ZT,ZW,Z6,Z8 and 50ZG,ZN,ZT,ZW,ZX,ZZ,Z2,Z3,Z6,Z7,Z8,Z9105
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) and high-capacity
power exhaust (48ZT,ZW and 50ZT,ZW,ZX,ZZ) units, add com-
ponent 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.
