NOTE(S):
a. If calculating static pressure for a 48 Series unit, be sure to add gas heat pressure drop from Component Pressure Drop table.
b. Fan performance is based on wet coils and clean 2 in. filters.
c. For return fan and high-capacity power exhaust units, add component pressure drop for economizer. Do not add component pressure drop for power exhaust.
d. See Component Pressure Drop data table before using Fan Performance tables.
e. To convert bhp to kW, use the formula:

Kilowatts = bhp x 0.746
Motor efficiency
See Physical Data table for motor efficiency.
