Fox Valve is the leading global supplier of venturi eductors and venturi transport systems for pneumatic conveying of powders, pellets, and bulk solids. They enable the use of low pressure air ( below 14 psig or 1 bar) to be used to move powders, pellets, and bulk solids with no moving parts. Fox has sold venturi eductors continuously since our first sale, in 1963, of a stainless eductor for use in transporting plastic pellets with air at 4 psig.
Fox Venturi Eductors convert the output of a blower into suction that can be used to entrain and feed powders, pellets, and bulk solids into a pneumatic conveying system. Because they have no moving parts, they can operate almost entirely maintenance-free. The eductor acts to compress the air/solids mixture to a pressure adequate to overcome losses in the downstream convey line. The eductor has three connections:
Fox Venturi Eductors are used to feed bulk solids, such as powders, pellets, flakes, and particulates, into positive, dilute-phase conveying systems. They are commonly used in place of rotary valves where airlocks simply cannot perform adequately.
