E-Vac® – Vacuum Generators – Vacuums for lifting, clamping, mounting and placement!
What Is The E-Vac?
The compressed air powered E-Vac single stage vacuum generators are the low cost way to create a vacuum for:
- Pick and place
- Clamping
- Lifting
- Chucking
- Alignment
- Surface mounting
- Vacuum forming
E-Vac compressed air powered vacuum pumps provide instantaneous response and are most commonly used for pick and place operations.
Why The E-Vac?
The E-Vac vacuum generators have been engineered for high efficiency to minimize air consumption. These single stage, all aluminum units provide consistent, steady vacuum, unlike mechanical vacuum pumps. Dust and small particulates easily pass through the vacuum generator and they have no moving parts, making them maintenance free.
How The E-Vac Works
Compressed air flows through the inlet (1), then through a single directed nozzle (2). As the airstream exhausts, it expands and increases in velocity prior to passing through the venturi (3). A vacuum inlet tangential to the primary airflow (4) is located at the suction point between the orifice and the venturi. The airflow that is drawn through the vacuum inlet mixes with the primary airstream, then exhausts on the opposite end (5).
E-Vac Is Easy To Use
The E-Vac is available in two styles:
In-Line E-Vac Vacuum Generator
These single stage, cylindrical units are compact and easy to mount at the point of use. They can be held in playe by threading them directly onto a compressed air line or with the use of a mounting clip. There are 7 models available for with porous materials, like cardboard, with vacuum levels up to 21 inHg (71 kPa) and vacuum flows up tp 18.5 SCFM (524 SLPM). There 7 models available for use with non-porous materials such as glass, with vacuum levels up to 27 inHg (91 kPa) with vacuum flows up to 15.8 SCFM (447 SLPM).
Adjustable E-Vac Vacuum Generator
This series of vacuum generators permits easy adjustment by simply loosening the locknut and turning the exhaust to increase or decrease the level of vacuum and vacuum flow. This style is also an excellent choise where large particulate may be present and passed through the vacuum system. There are 4 models with adjustable vacuum up to 25 inHg (85 kPa) and vacuum flow up to 81 SCFM (2,292 SLPM).

Select the E-Vac type.
Determine the weight of the part.
Multiply the weight by the vacuum cup safety factor for the total vacuum cup capacity needed.
Determine the number of vacuum cups needed.
To choose an E-Vac model number, consider the entire vacuum system from the E-Vac to the part.

Accessories Needed To Build Your Vacuum System
We offer you a variety of mufflers, tubing, check valves, and fittings that make it easy to build a vacuum system best suited to your vacuum application.
When using E-Vac vacuum generators, it is important to use a source of clean, dry compressed air that will keep them operating at their peak performance. For Automatic drain filter separators to keep the compressed air free of contaminants and moisture and other accessories please contact us.
Fittings and Tubing
The vacuum port of the E-Vac has an NPT thread (a vacuum cup can be threaded directly into it). For vacuum cups that are remotely, located, push-in connector fittings (most have global threads for use with NPT and BSP), or hose barb fittings can be installed on the E-Vac and the vacuum cup, Polyurethande vacuum tubing is available (10′, 20′, 30′, 40′ and 50′ lengths) to connect them. For best performance, the length of the tubing should be minimized to achieve the best attach and release times.
Check Valve
A vacuum check valve is available to hold the vacuum in case of compressed air loss. E-Vac vacuum generators that are used without a check valve will release the load if there is a significant drop in compressed air pressure or the supply of compressed air is lost.
Mufflers
Optional silencing mufflers are available that permit maximum exhaust of the E-Vac unit to cycle speed is not reduced. The Standard Muffler (for use with In-Line E-Vacs only) has a closed end and is suitable for applications that are free of dust and debris. The Straight Through Muffler is recommended where particulates are present since it will not accumulate debris that can erode performance. Straight Through Mufflers offer the best sound level reduction (up to 26 dBA).
