In-Line E-Vac Vacuum Generators

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.

Two Styles – Low Vacuum and High Vacuum

EXAIR manufacturers two styles of E-Vac – High Vacuum and Low Vacuum. The application will dictate which type of vacuum is most suitable.

Low vacuum units up to 21" Hg (71 kPa) are typically used for porous materials such as cardboard, and delicate materials. The low level vacuum prevents any warping, marring, dimpling or disfiguring of the surface due to excessive vacuum. This style generates more vacuum flow to overcome porosity and leakage.

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

Max Vac for listed models is 27" Hg

Max Vac for listed models is 91 kPa

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.

Choosing An E-Vac

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).
