Bhp — Brake Horsepower

FIOP — Factory-Installed Option

Watts — Input Watts to Motor

*Standard low-medium static drive range is 834 to 1064 rpm (for 208/230 and 460-v units). Alternate high-static drive range is 1161 to 1426 (for 208/230 and 460-v units). Other rpms require a field-supplied drive.

NOTES:

1.Maximum continuous bhp for the standard motor is 3.13 (for 208/230 and 460-v units). The maximum continuous watts is 2700 (for 208/230 and 460-v units). Do not adjust motor rpm such that motor maximum bhp and/or watts is exceeded at the maximum operating cfm.

2.See page 162 for general fan performance notes.
