The Bosch 300-CFM Dust Extractor delivers the high-performance cubic-feet-of-air-per-minute (CFM) rate for maximum dust extraction for heavy-duty concrete construction applications such as concrete cutting and surface grinding. The dust extractor’s powerful 17.5 Amp motor delivers a maximum 300 CFM, and it is designed to help users move toward compliance with the OSHA Silica Table 1 dust compliance regulation. The automatic on-board filter-cleaning system activates every 15 seconds to help maintain maximum suction power. The included HEPA filter captures 99.97% of particles at 0.3 microns and larger. The included three-layer heavy-duty filter bag helps to protect the filter and provides the optimal containment of dry dust. It also provides wet/dry operation, with a water-level sensor and drain hose. The extractor features a wheeled metal frame with dumping mechanism, metal castors and a height-adjustable push handle.  Includes: 17-Gallon 300-CFM Dust Extractor, HEPA filter, (5) heavy-duty three-layer filter bag, 16’ anti-static vacuum hose, elbow, and suction tubes / floor set.
