Vacuum Generators for Porous or Non-Porous Materials

EXAIR’s E-Vac Vacuum Generators are a simple solution for creating vacuum for a variety of different applications from: pick and place, clamping, chucking, lifting, surface mounting, and vacuum forming. Our In-Line E-Vacs are available in two different styles: porous or non-porous.

The material that you’ll be picking up will dictate which model is most suitable for your application. For porous materials such as paper or cardboard, we offer the low vacuum level, high vacuum flow vacuum generators. With vacuum levels up to 21” Hg and vacuum flows up to 18.5 SCSFM, this style generates more vacuum flow to overcome porosity and leakage. They can also be used to lift or hold delicate materials and prevent any warping, marring, dimpling, or disfiguring of the surface due to excessive vacuum.

Non-porous materials such as glass, steel sheet, and plastic are much more rigid and do not allow any of the vacuum flow to pass through the material. For these materials, EXAIR offers high vacuum units with vacuum levels of up to 27” Hg with vacuum flows up to 15.8 SCFM. These vacuum generators offer maximum holding capacity for heavy materials. Sizes are available with compressed air requirements as little as 2.3 SCFM at 80 PSIG and up to 30.8 SCFM for the largest and heaviest materials.

In addition to the vacuum generators themselves, EXAIR offers a variety of different accessories to help you build a complete system. To minimize the sound level and ensure you’re adhering to OSHA 1910.95, we have Standard Mufflers as well a Straight Through Mufflers. The Straight Through Mufflers offer the best level of sound reduction, up to 26 dBA!!

With no moving parts to wear out, EXAIR’s E-Vacs are virtually maintenance free when supplied with clean, dry compressed air. To maintain proper operation of your E-Vac, installation of an Automatic Drain Filter will remove any particulate and moisture from the air supply. In addition, oil removal filters are also available if your compressed air supply contains any oil as is common in many compressed air systems.

For pick and place or lifting applications, vacuum cups will be necessary. With a wide variety of different vacuum cups available: Small Round, Large Round, Oval, and Bellows, we can accommodate nearly any size or shape material. For heavier materials, round cups with cleats provide rigidity and ensure that the load remains stable. For applications on textured or uneven surfaces, Bellows style cups have convolutions that allow for the cup to quickly decompress when it touches the surface of an uneven part or material.

With all of the different options making a selection can seem like a daunting task. If you’re struggling to determine the most suitable E-Vac and Accessories for your application, give an Application Engineer a call today!
