The air king 42-inch belt driven drum fan is ideal to move a lot of air. The 42-inch blades are powered by a 1/2 HP ball-bearing, permanently lubricated motor. The motor moves 12,900 CFM on the high setting and 8,860 CFM on the low. This fan is sure to last as the blade, guards, and mounts are all constructed of durable powder-coated steel. As an added feature, it has rubber wheels and a carry handle, making it relatively easy to move. A 10-foot, 3-conductor type SJT power cord is provided for long reach and a side-mounted switch allows you to easily control the fan. It measures 47-by-19-by-45-inches (LxWxH) and weighs 93 pounds. About a dozen hours of use. Practically new, in tip top shape. Amazon lists this for $785.00 new and $579.00 used. Willing to deliver for cost of gas or p/u in SLC off of 1300 South and 900 West roughly.
