So I purchased an old centrifugal fan with 14in pulley on it. I also have a 5hp motor that's rated to 3600rpm. Does anyone know how to determine what's the proper speed for the fan? There is not specs or I'd tag on the unit. I want to know what size pulley to get for the drive motor. Pics attached.

Might be worth emailing Todd or Craig at Mainline? I've only ever dealt with commercially produced units so haven't had to think too much about rpm etc.

You can probably find performance curves for similar sized stuff on supplier websites which will get you close.
