Table 5 — Fan Performance — 48ZG,ZN040 and 50ZG,ZN040 Units Without Discharge Plenum*
LEGEND
*If calculating static pressure for a 48 Series unit, be sure to add gas
heat pressure drop from Table 30A on page 32.
NOTES:
1. Fan performance is based on wet coils and clean 2-in. filters.
2. See Table 30A before using Fan Performance tables.
3. Conversion — Bhp to kW:
See Tables 26-28 for motor efficiency.
