The heavy duty air conveyor X-stream™ ring-vac™ pneumatic system has literally no part that moves. It is able to convey material at a high rate over long distances easily. It deploys compressed air for a very powerful venturi action along it's length. This is done in a compact way so that the capacity for conveying over large distances is high. These conveying systems come in the standard and threaded versions. Clamp a standard sized hose to each end of the ring-vac™ so as to create a high energy conveying system. With the threaded version it is possible to just attach the hose to the threaded piping. No moving parts translates into a maintenance-free operation. There is a pressure regulator to control both capacity and flow. The system is available in 25mm, 32mm, 38mm, 51mm sizes. Any size beyond these can prove to be an impediment for most applications.
