Table 7 — Fan Performance — 48P2,P3,P4,P5055 and 50P2,P3055 Units without Discharge Plenum*
LEGEND
*If calculating static pressure for a 48 Series unit, be sure to add gas
heat pressure drop from Component Pressure Drop table.
NOTES:
1. Fan performance is based on wet coils and clean 2-in. filters.
2. See Component Pressure Drop data table before using Fan Perfor-
mance tables.
3. Conversion — Bhp to kW:
See Physical Data table for motor efficiency.
