NOTES:
1. The rpm’s shown for fan/blower are mid-range reference values for

factory-furnished drives. The appropriate drive for 50 Hz or 60 Hz
motor will be selected at the factory.

2. Contact factory if higher horsepower selection is required for a given

cfm and total static pressure.

3. The variable pitch motor sheave will allow an approximate ±15% rpm

adjustment from mid-range value. Unit size 08, 12, and 16 have

3

4

-in. bore fan sheaves. Unit sizes 20, 30, and 40 have one-in. bore

fan sheaves.

4. Consult factory for motor selections when outlet air temperature ex-

ceeds 104 F.

5. Single-phase motors are only available to one hp. Three-phase mo-

tors are available from
