NOTES:

1.Unit is available with the following motor and drive combina- tions: 7.5, 10, 15, 20 HP standard drive; 7.5, 10, 15, 20 HP medium-static drive; 7.5, 10, 15, 20 HP high-static drive.

For 7.5 HP standard drives, the drive range is 780 to 960 rpm. For 10, 15, 20 HP standard and 7.5 HP medium-static drives, the drive range is 805 to 991 rpm. For 10, 15, 20 HP

medium-static and 7.5 HP high-static drives the drive range is 960 to 1146 rpm. For 10, 15, 20 HP high-static drives the drive range is 1119 to 1335 rpm.

2.Italics indicates field-supplied drive required.

3.Manual backgroundManual background Do not operate in shaded area.

4.Static pressure losses must be applied to external static pres- sure before entering the fan performance table.

5.Interpolation is permitted, extrapolation is not.

6.Fan performance is based on filter, unit casing and wet coil losses.

7.This unit has one supply fan and one fan motor.
