Our Auto-Tumble Baskets are in production use in hundreds of wet-blast cabinets and thousands of traditional cabinets across the United States. In both the standard and giant Auto-Tumble Basket units, there is a large semi-sealed Stepper motor that is further enclosed in a complete enclosure. The motor is located strategically on the back side of the unit behind multiple metal plates, making water ingress very unlikely. We’ve never had a unit fail due to wet-blast or vapor-honing cabinet blasting use.
