DV-AH Air Powered Industrial DRY HEPA Vacuum The unique DV-AH Air Powered Dry HEPA Vacuum combines a powerful venturi with an ultra-efficient HEPA filter for extreme fine particle recovery applications. An anti-static pocket pre-filter traps particles as small as 1 micron to help extend the life of the HEPA filter, 99.999% efficient at 0.3 microns. It can produce a static water lift of 160" and an air displacement of 125 CFM. The unit features an external filter shaker to keep the filters clear and a detachable collection tank which can be wheeled out from under the vacuum without removing the vacuum head or filters.
