Table 36 — Fan Performance — 48ZA,ZC,ZE,ZJ,ZL,ZR,ZT,ZV,ZW075 Units*
LEGEND
*Fan performance tables do not include pressure drops for low heat,
high heat, or high-capacity coils. Refer to Component Pressure
drop tables on page 95 and add appropriate pressure drop data.
NOTES:
1. Fan performance is based on wet coils and clean 2-in. filters.
2. See Component Pressure Drop, Table 43, before using Fan Per-
formance tables.
3. Conversion — Bhp to kW:
See Tables 1A-1C, Physical Data, for motor efficiency
