For 7.5 HP standard drives, the drive range is 780 to 960 rpm.
For 10, 15 HP standard and 7.5 HP medium-static drives, the
drive range is 805 to 991 rpm. For 10, 15 HP medium-static and
7.5 HP high-static drives the drive range is 960 to 1146 rpm.
For 10, 15 HP high-static drives the drive range is 1119 to
1335 rpm.
2. Italics indicates field-supplied drive required.
3. 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. Bhp values are per fan. Watts values are per motor. Unit has
