I used to be in sales for a HVAC company, if you can give me the specs on the fan, Size, RPM, HP, SP, I could check my catalog when I get home, and give you a range of performance numbers. John

Dear John, Thank you for your prompt reply and help. What I am looking for is a centrifugal fan of any size that specifies blade angles (inlet and outlet), diameters (for tips the fan blades), number of blades and width together with its characterstics curves at any RPM. I just want to check if my program is correct for an already known fan with performance curves. I believe you can help me. Thank you again Mokee

Mokee, This is what I have, Single inlet 15" dia fan wheel tip speed = 3.93 x rpm outlet area 1.29 sf @1" SP 752rpm = 2580cfm 899rpm = 3870cfm @2" SP 986rpm = 2580cfm 1085rpm = 3870cfm I don't have listings for double inlet fans, I am not sure what inlet and outlet blades you are talkin about. And I am sorry I don't have more dimensions for the fan wheel. All I have left is the catalog, and don't have access to engineering specs. I do have more sizes and have backward curved blades, as well as other types of centrifical fans. John
