In operation the 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 they have no moving parts, they can operate almost entirely maintenance-free.
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.
Replace multiple screw conveyors and airlocks at the outlet of your dust collector with one or multiple eductors and one blower package. Reduce downtime, maintenance costs and environmental issues
