The HEPA Kits convert the company’s Velo and Velo Pro air movers for use as general air scrubbers. They fit on both the Velo and the Velo Pro air movers that feature low current consumption and multiple operating positions. With a housing measuring 2.5-in, shorter and half the height of traditional snail shell air movers, users can store and transport twice as many units. Additionally, HEPA Kits install in minutes with no tools necessary and filters replace easily. More info is available at http://www.drieaz.com/_DEC/DEC_Product_Base.aspx?decID=2127.
