bhp — Brake Horsepower ESP — External Static Pressure

NOTES:

1.A = Standard RPM/Standard Motor, B = Low RPM/Standard Motor, C = High RPM/Standard Motor, E = High RPM/Large Motor

2.Unit shipped with standard drive package with drive sheave 2.5 turns open unless otherwise requested. Field adjustment may be required for specified CFM.

3.ISO/AHRI rating point with standard drive package and drive sheave open 3.0 turns at .30 ESP.

4.Performance data does not include drive losses and is based on sea level conditions.

5.All airflow is rated at lowest voltage if unit is dual rated, i.e., rated at 208 volts for 208-230 volt units.
