Explosion-proof gyroscopic paint mixers turn paint containers end-over-end while simultaneously spinning instead of a shaking motion. They are suitable for high-viscosity materials in environments that need to mix large quantities of paint. Explosion-proof mixers are used in locations classified as hazardous, such as environments with welding operations or open flames. They mix paint as well as materials for automotive, chemical, laboratory, and marine applications. These explosion-proof machines must be installed by a certified electrician. Does not come with timer or power cord, must be provided by electrician. Please see pictures for some scratches/marks on the exterior of the casing. This unit has never been used, just has seen some wear to the outside.
