Bhp - Brake Horsepower
High Range Motor/Drive Required
NOTES:
1.Motor drive range is 690 to 893 for low range motor/drive and 852 to 1055 rpm for high range motor/drive. All other rpms require a field‐supplied drive.
2.Maximum continuous bhp is 3.70 for low range motor/drive and 5.25 for high range motor/drive.
3.See General Fan Performance Notes.
