The Minuteman X829 Series Vacuums conform to all EPA and OSHA guidelines and requirements for cleaning asbestos and other hazardous materials and filtering all toxic and noxious dust. Although specifically designed for asbestos particles, this vacuum is also effective in filtering other airborne pollutants such as cement, foundry and kiln dust, insecticides, fertilizer dust, coal dust, and many others. With an efficiency rating of 99.999% for particles 0.12 microns, the X829 Vacuums are particularly useful for clean-up after insulation operations on pipes, in removing asbestos-covered ceiling and wall material, and for vehicle maintenance procedures involving brakes, clutches, and other asbestos-containing materials.
