Porous and Non-Porous E-Vac Vacuum Generators

Getting a vacuum from compressed air seems a bit like magic, but it works and it works well. EXAIR’s E-Vac® Vacuum Generators are compressed air powered, single stage vacuum generators. They are a low cost way to create vacuum for pick and place, clamping, lifting, chucking, vacuum forming and other applications.

The Low Vacuum Generators are ideal for ‘porous’ types of applications.  When we say ‘porous’ we are describing those processes where a lighter vacuum level combined with higher vacuum flows are needed. A good example of this is lifting a cardboard box. The cardboard is not air tight, and when you place a vacuum on it, air is able to be pulled through the cardboard. To maintain the vacuum level, the air needs to be able to be pulled through the cardboard and exhausted as fast as it is being pulled through in order to maintain the vacuum level. This requires higher vacuum flow and the design of the Low Vacuum Generator allows for the development of a good vacuum level and a high rate of vacuum flow.

The High Vacuum Generator is ideal for ‘non-porous’ type of applications. ‘Non-porous’ are those processes where the material is air tight, and no or very little air can pass through. Material such as glass, ceramic, and steel are ‘non-porous’. Because little or no air passes through, the need for high vacuum flow is not as important, and the highest of vacuum level can be achieved. A perfect vacuum is 29.92 in-Hg, and the High Vacuum Generator is designed to reach vacuum levels of 27 in-Hg, or a 90% vacuum level.

Both the Low Vacuum and High Vacuum Generators come in 7 different sizes, ranging from light to very strong vacuum capabilities, to match any application. Special Kits are  available as a way to experiment with an assortment of vacuum cups to determine the best configuration.

And for maximum flexibility, EXAIR offers the Adjustable E-Vac Vacuum Generator. Engineered for high efficiency, compressed air can be minimized due to the ability to adjust and tune the vacuum flow and level to perfectly match the application requirements.

Life Hacking = Better Easier Life. So What Happens When You Hack Compressed Air?

The birth of the internet and personal computer brought to light a new form of hacking.  For many years now hacking has been considered a negative action, even criminal.  However, within the past several years the term lifehacking has come to mean a process of bettering your life through tips and tricks.  There are entire blogs and TED talks about life hacking, so that has gotten me thinking of how can EXAIR hack your compressed air system and turn it into a life hack?

All of our products are designed and engineered to make your life easier and better.  The best product I can think of to demonstrate this is our Super Air Knife With Plumbing Kit Installed.  This is an option for any of our Super Air Knives which are longer than 24″ that makes installation even easier on your end.  The plumbing kit has already connected air to each port on the Super Air Knife so all you have to do is plumb air to a single port at the end of the kit assembly.  See the picture below for a better idea.

Another item that has helped many customers is our Chip Trapper System.   This is essentially a modified or hacked Reversible Drum Vac System which  adds the benefit of filtering the liquid you are sucking up to a 5 micron level.  (Other filter levels/sizes available.) This means you can make your cutting fluid last longer and cut that rancid coolant smell in your machine shop down because the bacteria in the coolant doesn’t have any solids to live upon.  This also means that you won’t be giving your coolant reclamation company any of your valuable solids so you keep more of your scrap profits.

So if you are looking for a way to make your life easier while you are working with compressed air, let us know, we’ll see how you can hack your compressed air applications.
