Inlet Air Flow Rate 150A: (Nominal Capacity) 150 SCFM.95 x.72 x.94 x 1 = 96 SCFM (Corrected Capacity) Based on the correction factors the UA150A would be to small for this application. Try the UA250A (Nominal Capacity) 250 SCFM.95 x.72 x.94 x 1 = 160 SCFM (Corrected Capacity) For this application the UA250A would be the correct choice.
