Bhp — Brake Horsepower Input to Fan

Refer to this page for general Fan Performance notes.

NOTES:

1. Boldface indicates a field-supplied drive is required. (See Note 4.)

2. indicates field-supplied motor and drive are required.

3.Maximum continuous bhp is 4.20 with standard motor.

4.Standard motor drive range: 860 to 1080 rpm. All other rpms require field-supplied drive.

GENERAL NOTES FOR FAN PERFORMANCE TABLES

1.Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with confidence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected. For additional information on motor performance, refer to Indoor-Fan Motor Data table on page 89.

2.Values include losses for filters, unit casing, and wet coils. See page 88 for accessory/FIOP static pressure information.

3.Use of a field-supplied motor may affect wire sizing. Contact your Bryant representative for details.

4.Interpolation is permissible. Do not extrapolate.
