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.

Ready For Spring

Temperatures are changing here in the Midwest which means Spring is right around the corner. Basically what that means for Ohio is that it could be close to 70° and sunny one day and 32° with snow flurries the next. For my oldest son and I, the warmer temperatures mean camping and fishing are getting closer (YES!) but it also means that it’s time for the dreaded Spring cleaning and the yard work begins.

Having been a little preoccupied with our new family addition, I haven’t had much time to stay on top of keeping things tidy. In fact, my garage looks like the Tasmanian Devil had himself a good ole time (with the help of a certain 7 year old). The sidewalk and back patio both need pressure washed and our storage shed could use some attention as well. Hoping to get a start on these projects in the next few weeks!

In industry, keeping a clean work environment can be vital to maintaining a steady production flow. Luckily EXAIR has you covered with our compressed air operated Industrial Housekeeping Products. Requiring no electricity means there are no expensive parts to replace or motors to burn out from the rigors of industrial use. Designed to fit standard steel drums, the units are easy to use and operate.

Take for example our Chip Vac System designed to vacuum dry or coolant covered chips or other dry media. Or the Heavy Duty Dry Vac System which is similar to the Chip Vac but features a more powerful vacuum and holds up better to abrasive material (sand, glass, garnet) with its hardened alloy construction.

For liquid handling we offer our Reversible Drum Vac Systems that are capable of filling or emptying a 55 gallon drum in 90 seconds. Maybe you have suspended solids in your coolant that need filtered? The Chip Trapper System would be the ideal choice to separate chips from your coolant stream and then return the clean coolant back to the sump.

Finally for dusty environments, we offer our Heavy Duty HEPA Vac providing 99.97% filtration at 0.3 micron with it’s HEPA filter to trap dust and fine particles.

Understanding the need to keep things neat and clean, we are currently offering a free Vac-u-Gun with the purchase of an Industrial Vacuum System through 5/31/16.

Vac-u-Gun Promo

Order by 5/31/16 to take advantage!

If you need any help with selecting the right product for your needs, please don’t hesitate to give us a call.

EXAIR’s Industrial Housekeeping Products are Portable

?????????????????????????

I had noticed somewhat of a trend in my inquiries regarding our Industrial Housekeeping Products of late. It seems that customers want to use our Chip Vac, Heavy Duty Dry Vac or perhaps the Heavy Duty HEPA Vac with a really long vacuum hose. I’m talking like 50 or 60 feet worth of suction hose. And when I ask the customers why they want such a long hose, they say it is so they can reach all parts of their shop from a central location.

It did not occur to me until now that folks may not realize that, in fact, all of our Industrial Housekeeping Products are made to be moved around the shop, just like you would an electric shop vacuum with casters.

All of our Industrial Housekeeping Products have an industrial drum dolly available for them from the smallest 5 gallon sizes up to the big 110 gallon units. In fact, our Chip Trapper product comes with one included as part of the base system.

If you have a need to vacuum debris from multiple locations, moving the Industrial Housekeeping unit around the shop allows you to keep your vacuum hose as short as possible (we have 10 ft. hoses). With this configuration, you do not suffer the line losses associated with trying to create a vacuum across a 60 ft. long vacuum hose which results in lost performance. Dealing with a 10 ft. hose is also a lot less hassle than a much longer one.  It is a better idea to use a longer compressed air hose to supply your Industrial Housekeeping Vacuum system with compressed air and roll it around to each area where you need to use it. Compressed air travels through hoses much more readily than vacuum flows do.

EXAIR has all the necessary accessory items available including Drum Dollies and compressed air hoses to outfit the Industrial Housekeeping Products.

Award Winning HEPA Vac

Continuing my series of EXAIR award winning products for 2014.  Plant Engineering’s readers voted the Heavy Duty HEPA Vac a silver award for Environmental Health. The HD HEPA Vac differs greatly from most of the EXAIR products.  We often improve a work environment by reducing noise level from compressed air blow offs or limiting the energy usage of a facility by conserving compressed air, but when EXAIR introduced the Heavy Duty HEPA Vac, we entered a new area of environmental health.

hepafam_collection

High Efficiency Particulate Air standards are set by the US Department of Energy. Originally, the standards were created to protect workers, the public and the environment from particulate that may be found in DOE’s nuclear facilities. (For more information on HEPA filtration consult DOE-STD-3020-2005.) The Heavy Duty HEPA Vac filter meets the HEPA standards to filter a minimum 99.97% at 0.3 micron level.  Each filter is tested in strict accordance with IEST-RP-CC-007. After testing the filtration, vacuum and ventilation companies discovered the added benefit of using HEPA filtration is to remove particulate that may inflame allergies or asthmatic symptoms. Pollen, pet dander, and dust are physically too large to pass through the HEPA filter. For instance, most pet dander is 5 microns and will become trapped inside the circuitous air passage route inside the HEPA filter. Also, HEPA filters will even filter airborne pathogens.  Engineering Toolbox list several nominal particle sizes to give you the idea of scope. By meeting these strict standards, EXAIR’s Heavy Duty HEPA Vac can be used in a whole new industry where HEPA filtration is required.

Tries to imitate the late Billy Mays

But wait there’s more!

We haven’t even talked about the HEAVY DUTY DRY VAC component of the Heavy Duty HEPA Vac.  The Heavy Duty HEPA Vac features the same hardened alloy construction of the Heavy Duty Dry Vac.  This alloy holds up to abrasive materials such as garnet, crushed glass, sand or hard materials like stainless steel chips, pipe plugs, or brass piping caps.  We tested the conveying power of the Heavy Duty Dry Vac, it moved 32 pounds per minute of steel shot blasting media, 146% percent more than a standard Chip Vac.  With all this vacuuming power, it still maintains a surprisingly quiet 82 dBA of sound level.

The Heavy Duty HEPA Vac would be the perfect item to clean out that clogged filtration system, or to clean up that spilled kitty litter that will clog up a standard electrical vacuum. It will not blow tiny particulate all over your shop and it can help protect your personnel from airborne particulate.

EXAIR Could Save You $15 While Eating Lunch

At EXAIR we manufacture engineered compressed air products.  We have compressed air saving nozzles, safety air guns, vortex tubes, and even pneumatic vacuums – all engineered to be as efficient as possible.

Considering that compressed air is the most expensive utility to generate, it makes sense to keep compressed air use to a minimum.  Replacing open pipes used to blow off or cool an application with an EXAIR engineered product can save time and add OSHA compliance to a workspace.

Mold Application 1

Mold Application 2

For example, the photos above show a dry mold application.  The end user initially used drilled holes in a series of pipes operated at 80 PSI to blow off and cool the molds during production.  Not only was this an inefficient use of compressed air, it was also unsafe.

With an average hole size of 1/8”, and an average of (60) drilled holes per mold, the potential savings were HUGE!  An open 1/8” hole at 80 PSIG can consume 18.4 SCFM.  Replacing this drilled hole with an EXAIR model 1103 1/8” Mini Super Air Nozzle will reduce the air consumption to 10 SCFM – a savings of 47%!  With the potential to upgrade 240 drilled holes to an EXAIR engineered nozzle, the total compressed air savings are over 2,000 SCFM.

With a savings of 2000 SCFM, and a lunch break of 30 minutes, this end user would save 60000 SCF – during lunch!  At a cost of $0.25/1000SCF, this equates to a savings of $15.00 every day during lunch alone.  Extrapolating the savings out on an 8 hour shift, the savings become:

$240/day

$1,200/week  (operating (5) days/week)

$62,400/year  (operating (52) weeks/year)

In short, EXAIR nozzles put over $60k back into this company’s bottom line.

You can be next, just give us a call.
