NOTES:

1. Capacities shown are gross and do not account for fan motor heat. To determine net capacities, fan motor
heat must be subtracted from the gross MBh. To calculate supply fan motor heat use the following equation:

Fan motor heat (MBh) = 2.8 x fan motor brake horsepower.

2. To determine capacities at other than cfm shown, refer to the capacity correction factors in table.
