									High Static 15 HP & Field Supplied Drive

1.Blower performance includes gas heat exchangers and 2” filters. See STATIC RESISTANCE table for additional applications.

2.See RPM SELECTION table to determine desired motor sheave setting and to determine the maximum continuous BHP.

3.kW = BHP x 0.82.
