This  variable speed blower produces warm air by circulating it past the motors, keeping them cool in the process, then supplying it through a 15ft hose with a special blower tip provided. The blower has two high speed motor turbines providing 55,329 feet per minute of blow power. It may be suspended or set on the floor or can be used together with a second blower on the Sullivan's Blower Cart.
