Refer to factors on page 54 to convert numbers above to the desired metric units.
The standard AMCA class range is shown by the shaded areas. Standard carbon steel fans may be used up to the Maximum Design RPM as listed above for each fan class.
For minimum motor size required see “Fan Starting Requirements,” page 9.
If the Maximum Safe Operating RPM is not shown, consult the factory.
Performance shown is for Installation Type B - Free Inlet, Ducted Outlet.
Performance ratings do not include the effects of appurtenances in the airstream. Power rating (BHP) does not include drive losses.
All capacities listed above are based on standard Air Density of 0.075 Lbs./Cu. Ft. at 70°F & 0 Ft. elevation (1.2 kg/m
