You can now get a Transvair ® Venturi Eductor (TVE) furnished as part of a complete system. Systems will be integrated so all associated compo- nent pieces of equipment are reliable and cost effective. With the TVE Systems, velocities are matched to the application with the proper pick-up and average conveying velocities. Collecting filters have the proper cloth area. Power units are sized for reliable conveying and efficient use of the motor horsepower. Inlet hoppers are designed to efficiently feed the material into the venturi eductor. Transvair ® Venturi Eductor is accurately fabricated and machined in critical areas We have designed the various parts of the TVE to make it the most efficient unit on the market. The diffuser entrance is designed with a smooth bore and taper eliminating objec- tionable shock and eddy losses. The nozzle is machined to a precise center to the diffuser throat tube. The nozzle position is adjustable so that fine tuning may be done after installation for best performance. The mixing section or entry area to the diffuser throat is conical to increase flow in the throat. The Transvair ® Venturi Eductor’s diffuser throat is parallel producing a higher maximum inlet vacuum when compared to other designs. The throat length is calculated for optimum performance. The diffuser throat outlet expands to get proper static pressure regain and air/ material acceleration. The length of the outlet diffuser is calculated for maximum pressure recovery efficiency.

Properly designed venturi eductor systems are reliable and require little maintenance. The systems are most valuable in conveying applications when the material is transported at a rate less than 6000#/hr and over combined vertical and horizontal distances of up to 300 feet in total length. Venturi eductor systems are positive pressure dilute phase pneumatic systems that can convey a variety of bulk solids materials. The venturi eductor replaces the rotary valve that is normally used as an airlock and feeds material into the pneumatic conveying line. The problems encountered when using rotary valves, like air blow back and pellet clipping, are eliminated with the venturi eductor. Now, Venturi Eductor Systems designed by a Pneumatic Conveying Company. Until now, venturi eductors were supplied by companies that had little or no experience in the designing of dilute phase pneumatic conveying systems. These manufacturers have dispensed a lot of bad information, misinformation and have installed many venturi eductor systems that do not work. These companies do not understand pneumatic conveying fundamentals, including filters, Transvair ® Venturi Eductor - most efficient with the highest regain and proper air/material acceleration
