The Dust Muzzle Dust Collector uses the centrifugal forces created by the grinding wheel to force the dust out of the side exhaust port. When connected to any standard 2 hp vacuum, the Dust Muzzle dust shroud can remove up to 95% of the pollutants at the point of origin. It is available as the new Dust Muzzle Ultra, the Original Dust Muzzle and the Jaw Muzzle System.
