You might try Home Depot - their attic fans are designed to circulate a lot of heated air, and the whole system is under $125 (with thermostat). I think the fans are generally axial, but some were centrifugal. 12000 CFM is a lot of air to move. I think there are centrifugal (squirrel cage) fans in "swamp coolers ", so you could try looking for that too at second hand stores or calling HVAC contractors and telling them you'll take one of their hands (so they don't have to dispose of it). Failing that, you could try a demolition contractor and pull off some industrial fans from old buildings. Check out the web link below for some new fans: |
