NOTES:													LEGEND
1. Grey cells indicate field-supplied drive is required.												Bhp — Brake Horsepower
2. Maximum continuous bhp is 2.90.												Watts — Input Watts to Motor
3. See general fan performance notes.												*Motor drive range: 1300 to 1685 rpm. All other rpms require field-supplied drive.
