The HEPA Wet+Dry Pro Dustless Vac with Upgraded Equipment Set can be attached to a dust collection shroud for dust control when grinding concrete. The Dustless Vac can be used to collect any type of dry debris and any type of wet debris. With the flip of a switch, the exhaust system can be diverted to a single exhaust port that can blow air through your hose rather than sucking air when needed. The Dustless Vac features a 138 CFM motor, a certified HEPA System, dual exhaust ports, a deflector shield that protects your filter, and a hydrophobic polyester filter. The Dustless Vac features a semi-automatic cleaning mechanism that allows you to clean the filter without opening the vacuum. The Dustless Vac comes with replaceable vacuum bags and works with Dustless Technologies Wunderbag. The Dustless Vac is also medium size and easy to carry with its ergonomic carrying handle. The upgraded equipment set comes with a HEPA floor tool, 12 foot crush proof hose, HEPA filter, a wet+dry floor tool, 8 foot hose with hand cuff, crevice tool, round brush, wet screen filter, and two vacuum wands.
