Bhp — Brake Horsepower Input to Fan

NOTES:

1.Boldface indicates a field-supplied drive is required. (See Note 3.)

2.Maximum continuous bhp is 1.20 for standard motors; 2.40 for high-static motors.

3.Motor drive range: 760 to 1090 rpm for standard motors; 1075 to 1455 rpm for high-static motors. All other rpms require field-supplied drive.

4.See page 93 for general fan performance notes.
