Accessories
Accessories Needed To Build Your Vacuum System
EXAIR offers a variety of mufflers, tubing, check valves, and fittings that make it easy to build a vacuum system best suited to your vacuum application. In addition to these E-Vac vacuum generator accessories, there are other items that can help with the preparation and control of the compressed air.
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. Automatic drain filter separators to keep the compressed air free of contaminants and moisture are recommended. Oil removal filters that remove oil particulate that is common to many compressed air systems are available. Pressure regulators, shutoff valves, compressed air hose, fittings, and solenoid valves (to electrically turn the compressed air on and off) are available as well.
Mufflers Optional silencing mufflers are available that permit maximum exhaust of the E-Vac unit so 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 particulate is present since it will not accumulate debris that can erode performance. Straight Through Mufflers offer the best sound level reduction (up to 26 dBA).
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) can be installed on the E-Vac and the vacuum cup. Polyurethane 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. It is designed for high flow so it doesn’t restrict airflow or slow the vacuum operation. Maximum vacuum can still be achieved without affecting the performance. 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.

Adjustable E-Vac Vacuum Generators
Choose the E-Vac by the SCFM (SLPM) flow that best suits the performance needed for your application.Adjustable E-Vac Kits give you the ability to experiment with an assortment of Vacuum Cups. E-Vac Kits include a Muffler, an assortment of (4) pairs of Vacuum Cups (closely matched to the performance of that E-Vac), (2) straight, (2) elbow and (1) tee vacuum fittings, 10' of vacuum tubing and a mounting clip.
Deluxe Kits include the same items as the standard kit with the addition of an automatic drain filter separator for the compressed air supply and pressure regulator (with coupler).
Set The Vacuum And Flow To The Application Requirements
Adjustable E-Vac vacuum generators are ideal for applications where a variety of vacuum levels are required, which is often the case when lifting a variety of materials. The amount of vacuum flow is easy to adjust. Simply loosen the lock ring by turning it counterclockwise, then, turn the exhaust of the Adjustable E-Vac to increase or decrease the flow. Once the desired level of vacuum and flow are obtained, the lock ring can be tightened to hold that setting. Tuning the vacuum and flow to the application requirements will help to minimize compressed air use.
Adjustable Vacuum Generator Performance
The amount of vacuum created varies with the porosity of the load being picked up. Units come from the factory set to 15" Hg (51 kPa). A maximum of 25" Hg (85 kPa) can be achieved on a solid, non-porous surface, but will require increasing the air consumption and vacuum flow.Adjustable Vacuum Generator Performance15" Hg (factory setting) | ||||||||||

How The Adjustable 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). The amount of vacuum flow can be adjusted. When facing the exhaust end, loosen the lock ring (turn counterclockwise), then turn the exhaust. To increase flow, turn the exhaust counterclockwise. To decrease flow, turn the exhaust clockwise. Be careful not to unthread the exhaust completely. There will be a point where no more vacuum flow can be achieved. The amount of vacuum created varies with the porosity of the load being picked up. Units come from the factory set to 15” Hg if used on a solid, non-porous surface. A maximum of 25” Hg can be achieved on a solid, non-porous surface, but will require increasing the air consumption and vacuum flow. |

Increased Energy and Vacuum Efficiency
![](/media/wysiwyg/store_images/evac_build.jpg)
Energy and vacuum efficiency are not limited to the Adjustable E-Vac vacuum generators. All E-Vac styles and models can offer significant improvements when looking to reduce the amount of compressed air used for a specific vacuum application. Once the appropriate amount of vacuum and flow for the application are determined, it is important to select the appropriate model that will deliver the best performance while using the least amount of compressed air that it takes to do the job.
Many companies have a centralized vacuum system where the vacuum is generated at a location that is far away from the point of use. The long runs of piping through the plant produce line loss and it is often difficult to obtain that perfect balance of vacuum and flow required for an application. The compact In-line E-Vac vacuum generators eliminate this problem since they can be mounted at the point where the vacuum source is needed. EXAIR’s Application Engineers can help you to select the E-Vac vacuum generator and vacuum cups that provide the right amount of lifting capability while minimizing the amount of compressed air usage.
Other Applications for the E-Vac
![](/media/wysiwyg/store_images/inlineevacapp1.jpg)
E-Vacs are used in many other “non-lifting” applications. They are commonly used for vessel evacuation, clamping, chucking, and other work holding applications. Many types of automated equipment use vacuum to evacuate, grip, hold, align and insert parts. These vacuums can be used for surface mounting, vacuum packaging, bag opening, label placement, carton forming and container evacuation.
Another popular application is using the E-Vac for liquid sampling. This process can easily be accomplished using an E-Vac vacuum generator attached to a liquid holding tube. When the tube is dipped into the vat, tank or container, the compressed air is turned on so it draws a specific volume of liquid up into the tube. When the compressed air is turned off , the liquid flows from the tube and can be dispensed into a container or machine to be analyzed.
Choosing An E-Vac
E-Vac® Vacuum Generators Are Easy To Use
The construction of the E-Vac is aluminum. The vacuum inlet can be easily connected to existing tubing, piping and hose. Durable vinyl vacuum cups for pick and place applications are available. Optional silencing mufflers are available that permit maximum exhaust of the E-Vac unit so cycle speed is not reduced.
Choosing The Appropriate E-Vac Vacuum Generator
EXAIR’s E-Vac is available in 2 styles that include the In-Line E-Vac and Adjustable E-Vac. Each design has been engineered for use in a variety of applications. 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.
In-Line E-Vac Vacuum Generator

This series of single stage, cylindrical vacuum generators are compact and easy to mount at the point of use. The In-Line E-Vac can be held in place by threading them directly onto a compressed air line or with use of a mounting clip. Each In-Line vacuum model has a specific level of vacuum and flow. This style can easily pass dust or small particulates. There are 7 models suitable for use when lifting porous materials (like cardboard). The “porous” models have vacuum levels up to 21"Hg (71kPa) with vacuum flows up to 18.5 SCFM (524 SLPM). There are 7 models for use with non-porous materials (like glass) that have vacuum levels up to 27" Hg (91 kPa) with vacuum flows up to 15.8 SCFM (447 SLPM).
Adjustable E-Vac Vacuum Generator

This series of Adjustable E-Vac single stage vacuum generators permit easy adjustment by simply loosening the locknut and turning the exhaust to increase or decrease the level of vacuum and vacuum flow. These are ideal for use with porous and non-porous materials where the load can vary. Vacuum flow is easily increased when the vacuum is being used on a porous surface. This style passes dust and larger size particulates so there is no loss in vacuum, making it the best choice when working with dirty, dusty materials (such as concrete mix, plaster, etc.) There are 4 models with adjustable vacuum up to 25"Hg (85kPa) and vacuum flow up to 81 SCFM (2,294 SLPM).
