LEGEND	NOTES:
Bhp — Brake Horsepower Input to Fan	1.	Boldface indicates field-supplied drive is required.
	2.	Maximum continuous bhp is 5.25.
Watts — Input Watts to Motor
	3.	See page 70 for General Fan Performance Notes.

*Motor drive range: 830 to 1130 rpm. All other rpms require field-supplied drive.
