E-Vac Vacuum Generators- For More Than Just Pick and Place

A textbook application for vacuum generators is the ‘pick and place’ function.  With ever increasing automation and robotic cells, more and more opportunities present themselves to utilize the E-Vac Vacuum Generator as a part of the system to ‘pick up’ an object and ‘place’ it in a new position. But the E-Vac’s can be used for many more types of applications.

In-Line E-Vac

Another popular usage is to hold something in place. One of our customers uses an array of Adjustable E-Vacs to pull a vacuum and hold down various sizes of Styrofoam sheets during a machining operation. The previous system was a 1 hp blower type, and did not offer any flexibility for handling different size sheets. Sheets would slip and produce off quality results. After installing the new design, the system was able to handle any size sheet, and scrap levels went down dramatically.

Adjustable E-Vac

A unique implication that was solved with an E-Vac was to deflate sporting balls.  The customer printed custom logos, and preferred the items to be flat for the printing operation. Using a commercial grade electric shop vac didn’t completely deflate the balls, and motors burned out often.  Using a low vacuum In-Line E-Vac with a quiet Straight Through Muffler, the customer can now quickly and quietly, fully deflate the balls.

Another popular use for the E-Vac is to pull a vacuum for drawing up liquids or gases. A customer that manufactures automotive seats was having issues with the process, where the expanding foam was producing a gas, and the gas would produce pockets and voids in the foam after setting.  The customer used a model 800017 In-Line E-Vac to create a vacuum inside the mold and draw off the gas, eliminating the pockets and the voids in the final product.

Lastly, as I am big fan of recycling, anything and everything, we worked with a customer that recycles the old CRT style of computer monitor  (remember those?) The housing would be sawed in half, so that access to the internal components could be made. Because of the variability in the size and shape of the monitors, the customer was using an adjustable chuck system, which took time to set-up for every monitor, each being a bit different. To speed up the process, an EXAIR In-Line E-Vac and 5″ Suction Cup was implemented, and the monitor held in place by the screen, which was was very consistent in shape from monitor to monitor. This change reduced the set-up time required.

These and other Applications for the E-VACs and all other EXAIR products can be found on the EXAIR website on the Products page, under the Related Info section toward the bottom of each page.

FREE Vac-U-Gun Offer!

A couple weeks ago I wrote a blog titled, Spring Cleaning All Around, outlining just a few of the many  features of our Industrial Housekeeping Products. All of these products are compressed air operated, have no moving parts and require no electricity, making them a safe and virtually maintenance free option for industrial clean up.

We are currently running a promotional offer, where if you purchase one of these products by May 31, 2015, we will include a FREE Vac-U-Gun, a $98 Value!!! (Use the promotional model number within the promo to receive the offer).

Vac-U-Gun Promo

Just click the photo for the promotional Model #

The Vac-u-Gun can be used as a blow gun, vacuum or for product transfer. Using only 13 SCFM @ 80 PSIG of compressed air, the unit produces a high output airflow on one end and creates a vacuum on the other end. In blow off mode, the unit provides 9 ounces of high velocity, forceful airflow. By changing the orientation of the nozzle insert, the unit can be converted into vacuum mode, producing -29.5″ H20 vacuum, use the bag attachment for general clean up. The output end can be connected to an 1-1/4″ smooth bore hose, allowing for the transferring of dry media. Again, there are no moving parts or electricity required to operate, so you get the convenience of 3 separate tools all in one single, safe hand held device!

Vac-u-Gun orientation

Simply change the nozzle insert orientation to quickly change between blowoff mode or vacuum mode.

Of course, if you need any assistance with selecting the right Industrial Housekeeping Product, you can always contact an application engineer.

Spring Cleaning All Around

Now that Spring is officially here, my “honey-do” list has grown quite substantially as of late. Besides all the work we’ve done inside the house, moving our first son to his new room and putting the nursery back together for our second’s arrival, we now need to focus on the outside of the house (of course this is what my wife thinks is the #1 priority and hey, she is 9 months pregnant so I am going to agree!).

Spring Cleaning

They way I felt over the weekend!

First on the list is pressure washing the siding and since we were expecting temperatures near 65° this past Saturday, I wasn’t going to mind being outside. One problem though, the pressure washer was buried in the garage behind plastic tubs of old baby clothes (thank goodness we held on to these), bicycles, bags of old toys/clothes for donation and every other thing we’ve “needed to hang on to”, which meant that I was going to need to clean the garage before I could clean the house. Adding another item to the already lengthy, spring-cleaning list.

Are you looking to do some clean up around your facility? If so, EXAIR has you covered with our Industrial Housekeeping Products. ALL of these units are compressed air operated and require no electricity to operate so there are no motors to wear out or moving parts, making them virtually maintenance free!

For liquid only clean up, we offer 3 different products:

Reversible Drum Vac – attaches to any standard 30, 55 or 110 gallon closed head drum. Capable of empty or filling a 55 gallon drum in less than 2 minutes.

High Lift Reversible Drum Vac – Up to 15’ of vacuum lift and able to empty or fill the same 55 gallon drum in 85 seconds

Chip Trapper – incorporates the Reversible Drum Vac to filter solids from liquid and traps them in a reusable filter bag. The unit can they be turned into a pump to empty the filtered, clean liquid back to a tank or reservoir.

For dry materials, we offer 3 different products as well:

Chip Vac – Used for vacuuming wet or dry chips and deposits them into a steel drum.

Heavy Duty Dry Vac – Similar to the Chip Vac but made of hardened alloy construction for abrasion resistance and a higher vacuum rate.

Heavy Duty HEPA Vac – Used in dusty environments to filter contaminants to HEPA standards while providing the same high vacuum rate.

For help selecting the right product for your application, give us a call at 1-800-903-9247.

What Makes Compressed Air Vacuums Better

I was recently given an article that was titled, “Shop Vac Flaws Grind Use to a Halt”.  This article was written by a gentleman whose original electric vacuum had declined in performance which led to acquiring a new model electric vacuum. The conclusion he draws in the end is, an old worn out decreased performance electric vacuum is better than a new electric vacuum. EXAIR knows the only comparison you can make with electric vacuums is to compare one to another – when comparing an electric vacuum to a pneumatic powered vacuum, there is no comparison. A pneumatic vacuum with no moving parts to wear out, break or decline in performance is a better vacuum.

In the end the author goes back to using his old vacuum because it didn’t require as much maintenance as his new unit.  This is where the beauty of a compressed air powered vacuum comes into play.  If he would have originally purchased a unit such as our Chip Vac or our Heavy Duty Dry Vac, which are both available in 5, 30, 55, and 110 gallon sizes, he wouldn’t have experienced any of these problems.  Our units have no internal moving parts, no bearings to grease or wear out, no motors to oil or clean. The author’s electric vacuum was missing a screw, EXAIR’s level of quality inspection eliminates the possibility for a product to arrive without a fastener.

Our units will not lose suction over time because the impeller is weak,  this is because there is no impeller to even worry about.  The only maintenance item you will encounter on our unit is the 0.1 micron filter bag which is washable and reusable.  This means you could have one vacuum that will last decades and will not need to be repaired every year.

The EXAIR Chip Vac has the equivalent suction force of around a 5 HP electric vacuum while the Heavy Duty Dry Vac will be equivalent to around a 7 HP vacuum.   No matter which unit you would choose to try they are both backed by EXAIR’s 30 day guarantee, along with our 5 year built to last warranty.  I don’t know of any electric vacuum cleaner made for shop use with a warranty or guarantee that can come close to that.  So why buy something that was designed by monkeys, choose something that was designed and made by experts in their field who stand behind what they make.
