Wet-dry dust extractor
Bosch's Wet/Dry Dust Extractor is an industrial-grade powerhouse with a maximum 300 CFM (cubic feet of air per minute) capacity that filters fine dust, coarse dirt and liquids. It features a 17-gallon capacity and an auto filter cleaning that activates every 15 seconds with a HEPA filter that captures 99.97 percent of particles at 0.3 microns and larger. It also features a high-performance 17.5-amp motor to maintain the maximum 300 CFM capacity and is ideal for heavy-duty applications, including concrete cutting and surface grinding with larger 7 and 9-inch grinders and up to 12-inch cut-off tools, the company says. A water-level sensor helps preclude overfilling and features a discharge hose for easy drainage.
