NOTES:
1.Static pressure losses (i.e., economizer) must be added to exter- nal static pressure before entering Fan Performance table. See Accessory/FIOP Static Pressure table on page 52 for more information.
2.Interpolation is permissible. Do not extrapolate.
3.Fan performance is based on wet coils, clean ®lters, and casing losses.
4.Maximum continuous bhp is 10.2 for
5.Deduct 0.3 in. wg static pressure for high heat units at or above 10,000 cfm.
