Material Transfer Venturi www.nbe-inc.com/accessories

VEA-Series
The principle operation of the Venturi is similar to a jet pump.
Compressed air is fed into an outside annular ring that has a
number of orifices leading into the main tube of the transduc-
er.
As the compressed air exits from the orifices, its velocity in-
creases to supersonic speed.
The air meeting in the center of the tube rotates with a
twisting motion similar to a worm screw. This cyclonic flow
creates a powerful vacuum, capable of drawing particles into
and through the transducer.
