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!

EXAIR’s Industrial Housekeeping Wet Vacs: The Reliable Alternative to Electric Vacuums

EXAIR manufactures a variety of Industrial Housekeeping pneumatic vacuum systems for a range of applications with dry or wet materials. We have systems suitable for use with dry materials only, wet materials only, as well as one capable of handling both wet and dry. For the purposes of this blog, I’m going to focus on EXAIR’s systems designed for use with liquids.

The Reversible Drum Vac is a compressed air operated vacuum system designed to quickly attach to any closed head 30, 55, or 110 gallon steel drum. The high-powered vacuum allows you to fill a 55 gallon drum in less than two minutes. With the simple turn of a knob, the stainless steel pump quickly empties the drum as well.

For thicker more viscous liquids (up to 1400 cP) or for when the application requires lifting the liquid from below-grade sumps, our High Lift Reversible Drum Vac is the best option. Operating in the same manner as the Standard Reversible Drum Vac, the High Lift RDV provides the extra power you need to move liquids from below grade work areas, sumps, or tanks up to 15’ deep. Both the Reversible Drum Vac and High Lift Reversible Drum Vac are offered in a variety of different systems both with and without the drum included.

Another system designed to be used with liquids is the EXAIR Chip Trapper. The Chip Trapper solves one of the most dreaded tasks in any machine shop: cleaning out the CNC coolant sumps. Over time, chips and shavings can make their way up into the coolant lines resulting in a clog. The coolant flow slows down or stops entirely, resulting in premature wear of expensive cutting tools, imperfections in the parts, or unacceptable product finish. When this occurs, if it is even noticed right away, the machine has to be stopped and valuable production time must be spent identifying the location of the clog and removing it. Another problem, one anyone working around CNC machines can attest to, is the rancid coolant smell that is a result of bacteria building up in the stagnant cutting fluid. Regularly cleaning this oil can reduce this smell, prevent premature tool wear or costly shutdowns, as well as extend the overall life of your coolant.

EXAIR’s Chip Trapper makes cleaning out your CNC machine coolant quick and easy!

Using either a standard or High Lift Reversible Drum Vac to provide the vacuum source, the Chip Trapper and High Lift Chip Trapper are capable of filling or emptying a 55 gallon drum in less than two minutes. It is able to pick up both the liquid coolant as well as any chips or shavings that are suspended in the coolant. The liquid is forced through a filter bag inside of the drum which contains any solid materials while allowing the coolant to filter out into the drum. Switching the knob on the Reversible Drum Vac and the directional flow valve to empty will allow the clean coolant to be pumped back out of the drum and reused.

The Chip Trapper is available in either 30, 55, or 110 gallon systems. It’ll also come with (2) 5 micron filter bags, other filter bags are also available ranging from 1 micron up to 200 micron filtration. Using a simple detergent, the filter bags can be washed out, cleaned, and reused multiple times. With no motors or impellers to clog or wear out, as well as no electricity requirement or shock hazard, the Chip Trapper comes with our standard 5-year Built to Last Warranty.

If you’re looking for a system that can handle both wet and dry materials, look no further than the EasySwitch Wet-Dry Vac. The EasySwitch is designed to handle the toughest of industrial cleanup jobs with ease. Available with a standard or HEPA certified filter for dry material, the system quickly and easily converts from vacuum mode to dry mode. Simply lift the latch and remove the filter element when vacuuming liquids. When you’re done, just place the filter insert into the lid and you’re ready to vacuum your dry materials.

Using only compressed air, EXAIR’s Industrial Housekeeping vacuums require no electricity. Without electricity and moving parts to wear out, there is no concern for failed parts, motor failure, or personnel safety associated with the use of electric vacuums in wet environments. All systems are available to ship same day from stock and are backed by our 5 Year Built to Last Guarantee. If you’re tired of replacing electric shop vacuums, EXAIR has the solution you need. Feel free to give us a call and we’ll be happy to help you select the best system for your application.

EXAIR’s Gen4 Ionizing Point: Compact Static Neutralization

Static electricity will be more prevalent under certain environmental conditions like low humidity. It will also appear on applications which have friction, separation, or insulating materials. Luckily, EXAIR has a wide-range of Static Eliminators that are designed specifically to address static issues in a wide variety of industries and conditions. Materials such as paper, plastic, or textiles will normally contain an equal number of both positive and negative ions. When subjected to friction, this balance can be disturbed if the atoms gain or lose an electron.

The static charge will then exert a force on nearby charged objects or grounded conductors (including personnel). These issues can also manifest in the form of dust clinging to product, product clinging to itself, rollers, machine beds or frames, materials jamming, and sheet feeding problems. Our Gen4 Static Eliminators have undergone independent laboratory tests to certify that they meet the rigorous safety, health, and environmental standards of the USA, European Union and Canada that are required to attain the CE and UL marks.

EXAIR manufactures two products in our Static Eliminator line that do not require any compressed air to operate, the Ionizing Point and the Ionizing Bar. Our Gen4 Ionizing Point is a compact, single point ionizer ideal for a range of winding, rewinding, or slitting operations. It can also be mounted through a duct to neutralize static charges due to moving air or materials.

The shockless Gen4 Ionizing Point delivers a high concentration of positive and negative ions for rapid static decay. It is capable of neutralizing static on the surface of your part or material within 2”. In this image below, a series of Gen4 Ionizing Points are being used to neutralize static from a playing card slitting operation.

The Ionizing Point is just one of our many Static Eliminators available from stock. If you’re experiencing static in any of your applications or processes, EXAIR has a solution available ready to ship. Give us a call and we’ll be happy to help point you in the right direction.

Eliminate Static on Hose, Tube, and Extruded Shapes w/ EXAIR’s Gen4 Super Ion Air Wipe!

Gen4 Super Ion Air Wipe

This time of the year it is not uncommon to feel a slight shock after walking across a carpeted surface and touching a door knob. This little “jolt” is a result of fast-moving electrons leaping from your body to the door knob, or vice versa. As your feet shuffle across the surface of a rug or carpet, your body will either gain or lose electrons. Touching a conductive surface then causes these electrons to leap from one place to another.

When an atom gains or loses an electron, it affects the balance that occurs within an atom. If an atom gains an electron, it now has more electrons than protons. This results in a negatively charged atom. The opposite can be said if an atom loses an electron, it now carries a positive charge. This charge imbalance is where static electricity comes from. Both positive and negative charges will remain static until contacted by or in close proximity to a conductive or grounded surface.

Static can be a problem in many industries contributing to a range of different process problems. Common problems include: dust clinging to product, product clinging to itself, rollers, machine beds or frames, materials jamming or curling, sheet feeding problems, and hazardous sparks or shocks to operators.

For eliminating static on the surface of pipe, cable, extruded shapes, hose, or wire, look no further than EXAIR’s Gen4 Super Ion Air Wipe. The Gen4 Super Ion Air Wipe provides a uniform 360° ionized airstream and is available in both 2” and 4” ID sizes. Its clam-shell design makes it easy to clamp around a part for neutralizing static electricity and contaminants.

The high volume, high velocity airflow attaches itself to the surface and wipes it down with static eliminating ions. The airflow stays attached to the surface and is effective up to 15’ away from where it’s mounted. It’s lightweight and easy to mount using the ¼-20 tapped holes on the back or can also be held into place with just rigid pipe.

If you’d like to talk about how EXAIR can help solve the static problems in your facility, give us a call. With a wide range of Static Eliminators available to ship same day from stock you can consider these problems a thing of the past!
