Negative air systems are used for the transportation of powder, grain, seed, and some vegetables. Blowers are used to create vacuum in a piping system. Product is then pulled into the pipe and drawn over to where it is needed. To discharge from the system, a cyclone receiver is used that drops the heavier product to the bottom where a rotary valve brings it out.
CFM Worldwide sells used rotary valves, air locks, Cyclone receivers and vessels, blowers, and bag house filters. We commonly have inventory from the following manufacturers: Air Lock, Mac, Shick, Sutorbilt, Fuller Roots, and Temco.
