Modu-Kleen® downdraft dust collector represents the latest technology to contain fugitive dust. Air enters at the top of the dust collector housing and flows downward to cartridge filters, improving filtering process and material-to-air ratio. Air velocities are much lower than those with other dust collectors, reducing load on each filer cartridge and extending filter life. Filters are positioned horizontally, requiring less floor space and making filter removal easier. Dynamic Air Inc. 1125 Willow Lake Blvd. St. Paul, MN, 55110
