The dust bull Uses vacuum power to gather dust while using a Gas powered saw while doing landscaping or masonry cuts. When using a vacuum system of 260 CFM or more, the dust bull captures nearly all dust generated while sawing. Using vacuum suction, the dust and debris are caught in their natural trajectory, giving you a truly dustless work environment. This protects you and your workers from breathing harmful silica dust while keeping the area dust free, saving time and money in cleanup. Four rubber feet along the bottom protect the shroud and the surface you are working on. The shroud will sit evenly to reduce strain on the worker, allowing you to rest the saw and the shroud on the ground. When working on sensitive surfaces You can be assured that the shroud will not scratch or scrape decorative work. When used with a 260 CFM vacuum system The dust bull is compliant with OSHA and EPA laws, keeping you and your workers safe from legal action and protecting you from harmful diseases caused by silica exposure. The dust bull is meant to fit most gas powered cut off saws. Included with the dust bull is a bolt kit meant to fit many models from a variety of manufacturers. It attaches to 2” hoses using a 2” soft hose cuff. Includes (1) dust bull, (1) Universal mounting bracket, and (1) bolt kit.
