Fox Venturi Eductors

3Sigma provides Fox Venturi Eductors for Pneumatic Conveying. Venturi Eductors are used to feed bulk solids, such as powders, pellets, flakes, and particulates into pressure, dilute-phase pneumatic conveying systems. If rotary valve airlocks cannot perform adequately for an application, Venturi Eductors are commonly used in its place. In operation the Pneumatic Conveying Venturi Eductors convert the output of a blower into suction that is used to entrain and feed powders, pellets, and bulk solids into a pneumatic conveying system. Because the pneumatic conveying Venturi eductors have no moving parts, they can operate almost entirely maintenance-free.
Pneumatic conveying Venturi Eductors can be fed or placed at the outlet of a hopper and will convey at a specified rate.  Venturi size, placement and line size all determine the actual flow rate.
Ceramic lined or hardened units are provided for abrasive applications.
