The Maxx Air 42 in. 2-Speed Portable Barrel Fan moves large volumes of hot air quickly and efficiently to keep people and machines cooled off indoors on the factory floor, in an industrial warehouse or commercial garage, or in a barn with livestock where high velocity air movement is needed. It features a heavy duty 22-gauge steel housing with rust-resistant grilles and requires no assembly. A quiet, yet powerful performance is what you can expect from this air mover: our 42 in. fan is belt-driven and has non-skid positioning legs for quieter, vibration-reducing operation. Pre-installed handles and diamond tread wheels move the unit to your desired location with ease. This model offers two speed selections to control the level of air circulation in your space.
