Equipped with a 28" (710mm) front mounted floor attachment, the DV-RV-2 Dry Roll-Vac Vacuum makes cleaning large warehouse and production areas fast and easy. The unit produces a static water lift of 90" (2.2m) and an air displacement of 224 CFM (6.3 m3/min). It is equipped with a pocket filter which traps particles down to 3 microns, an external filter shaker to keep the filters clear, and a detachable collection tank which can wheel out from under the vacuum without removing the industrial vacuum head or filter. The floor attachment can easily be removed to convert the unit into a multi-purpose industrial vacuum with conventional hoses and accessories. HEPA option available for even better cleaning results.
