Pelletron Corp.De-Dusting System
DeDusting systems are used in the bulk handling industry for cleaning of all kind of granular products. DeDuster systems reduce the scrap rate and increase profitability by removing unwanted contaminants prior processing, extrusion, and packaging. Traditional DeDuster designs require the product inlet and outlet to be in a straight line. While this design remains effective, the constant need to respond to changing processing conditions led to the design of the OS DeDuster series. The OS DeDuster series offers an offset inlet and outlet connection, for installation in existing angled silo outlet pipes, without changing the pipe geometry. All other features of the Pelletron DeDusting technology, such as the magnetic field and the Venturi zone, remain unchanged. Pelletron Corp., Lancaster, PA 717-293-4008 www.pelletroncorp.com

Dynamic Air Inc.Downdraft Dust Collector
With the Modu-Kleen downdraft dust collector, the air enters at the top of the dust collector housing and flows downward to the cartridge filters, improving the filtering process and the material-to-air ratio. Air velocities are much lower than those with a conventional dust collector, reducing the load on each filter cartridge and extending filter life. Cartridge filters are positioned horizontally, requiring less floor space and making filter removal easier. Personnel never have to enter the filter housing for general maintenance or for cartridge filter removal. This provides a safe and quick method of filter removal. For fast and easy inspections, a large, quick-opening door allows maintenance personnel to closely inspect each cartridge when required. In addition, any single cartridge can be removed without disturbing adjacent cartridges. Each cartridge filter has a built-in quarter turn bayonet mount, so no tools of any kind are required for cartridge removal. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com
