Low Vacuum In-Line E-Vac Vacuum Generators for Porous Applications

Choose the E-Vac by the SCFM (SLPM) flow that best suits the performance needed for your application.

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).

Accessories

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 keep compressed air free of contaminants and moisture. Oil removal filters that remove oil particulate that is common to many compressed air systems are also shown. Pressure regulators, shutoff valves, compressed air hose, fittings, and solenoid valves (to electrically turn the compressed air on and off) are also available.

Vacuum Cups - EXAIR offers vacuum cups in a wide variety of sizes and shapes to meet the needs of your application. EXAIR's vacuum cups are made of vinyl that is ideal for geneeral purpose applications and provides excellent resistance to wear. The Durometer rating (used to indicate the flixibility and stiffness of the cup) is A50. The operating temperature is 32°F (0°C) to 125°F (51.7°C).

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.

E-Vac 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 place by threading them directly onto a compressed air line or with the use of a mounting clip. There are 7 models available for use with porous materials like cardboard, with vacuum levels up to 21" Hg (71 kPa) and vacuum flows up to 18.5 SCFM (524 SLPM). There are 7 models available for use with non-porous materials such as glass, with 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 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 choice where large particulates may be present and passed through the vacuum system. There are 4 models with adjustable vacuum up to 25" Hg (85 kPa) and vacuum flow up to 81 SCFM (2,294 SLPM).

High vacuum units up to 27" Hg (91 kPa) are typically used for non-porous materials such as glass, steel sheet, and plastic.

In-Line E-Vac Standards and Certifications

EXAIR In-Line E-Vacs comply with OSHA's Safety Requirements, the EU General Product Safety Directive (2001/95/EC) and meet the noise limitation requirements of the EU Machinery Directive (2006/42/EC). All sound level measurements are taken at 3 feet away.
