Performance based on 0.075 lbs. per cubic foot density (air at 70 F and 29.92 Hg Bar).

Performance shown is for installationType B: free inlet, ducted outlet.

Power rating (BHP) does not include drive losses.

Performance ratings do not include the effects of appurtenances in the airstream.

When inlet vanes are used increase rpm 1 percent and brake horsepower 3 percent.

Fan tables cover part of fan operating range; fan curves show full operating range.
