Vac-u-Gun: Low Cost Vacuum, Blowoff and Transfer

What is the Vac-u-Gun?  It is a low cost solution to many types of cleaning operations within an industrial setting.  The Vac-u-Gun is a vacuum gun, a blow gun, and a transfer tool, all-in-one! It is lightweight, easy to use, has durable die cast construction, and best of all, no moving parts to wear out. Simply hook up to a compressed air hose, and get to work.

Vac u Gun Hose

The Vac-u-Gun contains a nozzle insert that dictates the direction of air flow and operation. By simply unscrewing the the cap, reversing the orientation of the nozzle insert, and re-installing the cap, the gun is changed from a vacuum device to a blowoff device, and vice-versa.

The Vac-u-Gun can be used in three modes- Vacuum, Transfer and Blowoff-

Vacuum Mode – Vacuum shavings, absorbents, sawdust, or spills into a reusable bag, or into a receptacle via the vacuum hose. Why blow it off and the have to sweep it up later?

Transfer Mode – Transfer small parts, pellets, or trim over long distances, using the smooth bore vacuum hose.

Blowoff Mode – Blow chips, water, coolant, or scrap away from the work area. The large 1-1/4″ diameter outlet directs the air over a larger area in less time. The Vac-u-Gun uses less compressed air than an ordinary blow gun.

Vac-U-Gun Specifications

There are many advantages to a Vac-u-Gun, and some are:

Low cost, no moving parts/maintenance free, durable die cast construction, easy to switch form vacuum to blow mode, safe – no electricity, meets OSHA pressure requirements, lightweight and portable, versatile, and quiet.

Versatile!  In just seconds, the Vac-u-Gun can transform from a powerful, handheld vacuum tool into an efficient blow gun or transfer tool for lightweight materials. Each Vac-u-Gun System comes with the attachments needed to suit numerous industrial applications.

EXAIR Industrial Housekeeping Vacuums – A Look at the Advantages Over Electric Vacuums

EXAIR‘s line of Industrial Housekeeping Products consist of liquid and dry vacuums that utilize compressed air to operate. They do not have electric motors which most ‘all purpose’ vacuums rely on.  In industrial settings with harsh conditions and rugged use, the Industrial Housekeeping Products are ideally suited for the everyday wear and tear.                               6091   6095.jpg

The heart of the EXAIR liquid type vacuums, like the Reversible Drum Vac, the High Lift Reversible Drum Vac, and the same range in the Chip Trappers is shown here. Installing onto an any closed head, 30, 55, or 110 gallon drum creates a high powered vacuum.  It can fill a 55 gallon drum in less than 2 minutes.  Then, with the turn of a knob, the the same pump quickly empties the drum. Useful for refilling coolant sumps, vacuuming floor spills, or transferring contaminated liquids to filtration tanks in minutes.  Flow rate can be controlled with the knob.  The Chip Trapper has an internal filtration system to separate the chips from the coolant, allowing for disposal of the solids, and for pumping of the clean coolant back into the sump.

5, 30, 55, and 110 Gallon Reversible Drum Vacs – A size to Meet Most Any Requirement

Also available are the dry/solid type vacuum systems, the Chip Vac, Heavy Duty Dry Vac and the Heavy Duty HEPA Vac which use the vacuum units shown below.6093                                                                    6097

The EXAIR Chip Vac and Heavy Duty Dry Vac is a powerful industrial vacuum for use on wet or dry chips. Both are for use with 30, 55, or 110 gallon drums, and the Chip Vac can also be used on a 5 gallon drum. The Heavy Duty HEPA Vac has the added benefit of the HEPA quality filter system.  Filtration per IEST-RP-CC-007 to 99.97% minimum filtration at the 0.3 micron level ensures performance meets the needed criteria.

When you look at the vacuum producing units, you’ll notice there is not an electrical cord.  Because the EXAIR Industrial Housekeeping Products utilize compressed air for operation, they do not have the same issues with wear, breakdown and failures as electrical type vacuums. There are no moving parts in the vacuum units to wear out or break.  They are maintenance free, just supply clean, dry air, and they will operate for a long time. For the the liquid type systems, there is a built in pressure/vacuum relief device and auto safety shut-off to prevent overfilling.

There are no motors and bearings to wear out and no impellers to clog.  The Chip Vac is 50% quieter than a comparable electric vacuum.  Safety is a top priority, and the use of the unit on wet floor and spills is not an issue.

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.

Think Of Quality And Service, Think Of EXAIR

As an Application Engineer at a direct sales manufacturing company, I get to talk to a LOT of people about potential uses for our quiet, safe, and efficient compressed air products. And, I’m happy to say, most of them I can even help with…even if the answer is “that’s just not gonna work.” Those are few and far between, however, and we can usually point someone in a better direction in those cases.

By the time we’ve “drilled down” into an application discussion far enough to make a product recommendation, we’ve got a pretty good feeling about it, and a vast majority of the time, our product solves the application in a big way. So big, in fact, that it makes them think of EXAIR again, and again.

Case in point: not long after I started here in 2011, I had the pleasure of helping someone out with some pick-and-place rigs on their packaging line…small products, bulk packaged for shipment to retail outlets. They used our Model 810003M E-Vac High Vacuum Generator and 900762 Small Round Vacuum Cups. Over the years, they’ve added some new products, and some more of the E-Vac pick-and-place rigs. It’s always good to hear from them, and I really believe the feeling is mutual.

EXAIR E-Vac Vacuum Generators provide a simple and reliable solution to pick-and-place applications.

Now, they want to automate a little clean-up operation where pilot holes are drilled in a plastic part, and are considering an intermittently operated vacuum. The concern is, if they use an electric powered one, the starting & stopping will take a toll on the motor. And they’re right.

So, the Model 6193-5 Mini Chip Vac System is up for consideration. Because it’s compressed air operated, constant starting & stopping is no problem…and, it’s generating vacuum immediately, so it’s ideal for quick bursts of cleanup suction action. No electric motor to burn out, no moving parts to wear – it’s a long term, maintenance-free solution.

Quiet and compact, the Mini Chip Vac is an ideal solution for a variety of industrial housekeeping needs.

If you’re an EXAIR engineered compressed air product user, I want to thank you for your business. If you’d like to discuss a particular compressed air product application (regardless of whether you’re a current user or not!) give me a call.

Improved Safety Benefits Employees & the Company

“Safety is Everyone’s Responsibility” is a slogan that companies around the world have adopted.

A refinery that processes palm oil from palm seeds had pipes throughout their facility to transport the oil. They would periodically have to clean the 10” diameter pipes as part of a maintenance program.  To do this, they would use a rubber plunger-like device called a pig to move through the pipe lines.  When they opened the piping system to install the pig, palm oil would leak onto the floor.  In their safety protocol, they would place adsorbent barriers around the spills and use a wet/dry vacuum to pick up the waste oil.  They would discard the liquid in a vat for disposal.  The wet/dry vacuum was limited in size to only hold 5 gallons because the operators would have to lift the container to dump the oil in the vat.  If the oil spills exceeded 5 gallons, then they would have to make multiple trips.  They wanted to get a better system as time was of the essence when you have oil on the floor.

6296 Deluxe RDV System

In speaking about their operations, they were needing to improve on their process and safety. I recommended the model 6296 Deluxe Reversible Drum Vac System.  This system uses a two-way pump and siphon tube that mounts into a 55 gallon drum easily without any modifications.  The pump uses compressed air, not electricity, to quietly generate a vacuum to a level of 96” of water. It does not have any moving parts, no motor or bearings to wear out, so it is very reliable and maintenance free.  The deluxe system comes with our Spill Recovery Kit for complete liquid pickup, a drum dolly, vacuum hose, and tool accessories with a holder.  In replacing their current system with the EXAIR Reversible Drum Vac, they could now vacuum a larger volume of liquid during excessive spillage without stopping.  Once the waste oil was vacuumed and contained, they could then just push their drum to the disposal vat.  With a simple turn of the knob, the two-way pump changes from a vacuum system to dispensing the waste oil into the vat.  This removed the need to lift any containers which could cause back damage to the operator.

As stated in the OSHA website, “Businesses spend $170 billion a year on costs associated with occupational injuries and illnesses — expenditures that come straight out of company profits. But workplaces that establish safety and health management systems can reduce their injury and illness costs by 20 to 40 percent. In today’s business environment, these costs can be the difference between operating in the black and running in the red.” Safety is everyone’s responsibility, and in using EXAIR products, you can do your part like the refinery above.

Choosing the Right Dry Vacuum – Chip Vac or Heavy Duty Dry Vac

A common question we get from our customers is, ‘I need a dry vac, should I use the Chip Vac or Heavy Duty Dry Vac.’  This is very good question, and we will take the time to better understand the application in order to best answer that question.

Both the EXAIR Chip Vac and Heavy Duty Dry Vac are designed to turn an ordinary 5 (Chip Vac only,) 30, 55, or 110 gallon open top drum into a powerful, industrial duty vacuum cleaner. Both are powered by compressed air, and have no moving parts to wear out or break, whereas the typical electrically operated system has motors and impellers that clog and break down quickly.  The Chip Vac and Heavy Duty Dry Vac are also quiet, at half the sound level of electric versions.

The Chip Vac is designed specifically for vacuuming chips. It creates a powerful direct flow that is ideal for metal, wood, and plastic chips.  Because it has a filter bag, in can also handle the occasional dusty material, and keep the surrounding air clean.

If the operation machines different materials, the lid can be removed from one drum and moved to another, to keep the materials separate for easy recycling.

The Heavy Duty Dry Vac was engineered to vacuum more dry material in less time with less wear. The hardened alloy construction resists premature wear and the increased power makes difficult jobs and harsh environments more easily handled.

The 110 Gallon  Heavy Duty Dry Vac provides maximum capacity for spill clean up

The Heavy Duty Dry Vac is ideal for abrasive materials such as steel shot, garnet, metal chips and sand, and is also useful for general purpose applications such as vacuuming floors, machines, work stations and machinery/equipment.

Like the Chip Vac, the Heavy Duty Dry Vac drum lid fits any open top drum, and can be moved from one drum to another facilitating recycling efforts.

Below shows the powerful performance of the Heavy Duty Dry Vac when considering large, heavy material and the increased performance you could expect.

EXAIR Chip Vac Removes Swarf and Keeps the Machining Center Running

The word of the day is “swarf”. Swarf is fine chips or filings of stone, metal or other material produced by a machining operation.

A company had four automatic profile cutting machines to cut aluminum stock.  They contacted me for help to improve their operation.  Each machine had a cleated belt conveyor to remove the swarf (or chips) from the cutting process.  Because the swarf was small in size, the chips could get around the edge of the belt and affect the conveying system.  Two of the four conveyors failed, and they wanted to find a better option to remove the swarf and keep the machines running.  They sent me a photo of the type and size of the swarf that was thwarting their conveying system.

EXAIR receives many calls about applications similar to this. I suggested the model 6193 Chip Vac System.  This assembly will fit onto a standard open-top 55 gallon drum which has a much smaller footprint than the conveying system.  The 0.1 micron filter allows for the air to escape and keep the fine particles inside the drum.  For this customer, once the drum was filled with aluminum chips, it was easy to rotate in an empty drum, sending the full drum of material to recycling.  The vacuum generator has no moving parts which makes it quiet, maintenance free, and long lasting.  It also creates a high vacuum level which was very useful when they attached it near the chip collection area.  The Chip Vac System was easy to install and it was very beneficial in keeping the machining area clean and running.
