Dirty Coolant in, Clean Coolant Out – EXAIR’s Chip Trapper Extends Coolant Life

In a machine shop one of the most dreaded tasks is always cleaning out the coolant sumps of the CNC machines. 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.

There are some machines out there capable of cleaning the oil and removing any chips or shavings, but these tend to be very expensive and not very effective. We tested a few different methods here at EXAIR in our machine shop. As a result of these tests we determined that the best foot forward would be to develop something ourselves. Enter the EXAIR Chip Trapper. Using either a standard or High Lift Reversible Drum Vac to provide the vacuum source, the Chip Trapper is 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.

After implementing the Chip Trapper in our own shop, we were able to increase the life of the coolant by 6x. In addition to the increased coolant life, a process that used to take up to 2 hours per machine now takes less than 10 minutes. The Chip Trapper quickly and easily pays for itself.

The Chip Trapper is available in either 30, 55, and 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. Do yourself (and your machine operators) a favor and get a Chip Trapper on order today. They’re in stock, ready to ship and start saving you time and money!

Product Overview – High Lift Reversible Drum Vac

Are you needing to move a thick fluid, move liquid farther or higher? Do you have a below grade sump or pit you’re looking  to empty? Then EXAIR has the solution for you, enter the High Lift Reversible Drum Vac. Like the standard Reversible Drum Vac, the High Lift RDV is a compressed air operated, liquid only vacuum with no moving parts or motors that can fail,  like those in traditional electrically powered vacuums. What separates the High Lift RDV from the traditional version is the higher vacuum it achieves which allows you to lift liquids up to 15′, move liquids up to 20′ and handle fluids with viscosity as high as 1400 centipoise.

The High Lift Reversible Drum Vac is a high powered vacuum able to lift liquids up to 15′ and fill a 55 gallon drum in less than 85 seconds!

The High Lift Reversible Drum Vac features a two-way pump constructed of stainless steel and a built-in safety relieve valve to avoid over pressurizing or over-filling the drum. Air consumption is minimal, at 43 SCFM @ 80 PSIG, while maintaining a low noise level of only 83 dBA. In “empty” mode, the HLRDV achieves a flow rate of 30 gallons per minute (water) to quickly empty the drum.

Systems are available in 30, 55 and 110 gallon capacities in 3 different variations:

The Standard Systems include the High Lift Reversible Drum Vac, shutoff valve, 20′ vacuum hose, standpipe, 90° quick release elbow and aluminum chip wand.

Model # 6295, 6295-30

And Premium Systems include all of the items in “Deluxe” Systems and adds the drum with lock ring and lid, heavy duty aluminum tools and 20′ compressed air hose.

Model # 6395, 6395-30, 6935-110

Do You Need 30 Days for Testing?

Not long ago while checking out of a motel my laptop bag that was attached to the handle on my suitcase fell forward and the impact shattered the screen on the laptop.  Upon turning the computer on I realized that a new screen was in order.

I waited until I arrived at home and found what I thought to be the correct monitor and quickly ordered it.  It arrived two days later and I painstakingly took the laptop apart and exposed the mounting frame.  The removal of the broken screen and the installation of the new was not too difficult but the cable connector was less than robust and was very tight.  Carefully I worked it back and forth and it came free.

Installation and reassembly went quickly and then I powered up the machine.  I was only greeted with a series of very loud and annoying beeps.  At that point I shut it down and called the company I purchased the screen from and described the issue.  They determined that the resolution of the screen was incorrect for my laptop and that I needed a different model.  They said I could return the incorrect one and upon inspection receive a credit less the return shipping.  At that point I ordered the correct screen and packaged up the wrong one and dropped it off at the parcel delivery service.

The new model arrived and it installed easily and worked perfectly.  I waited patiently and never did see a refund so I called the company and they said that it was an oversight on their end and that it would be corrected within 48 hours.  Sure enough they issued the credit and money was credited back to my account with one exception, the 40% restocking fee!

I can tell you that EXAIR is not that way!  If you order the wrong item or are not satisfied for any reason and the item was purchased within the last 30 days we will facilitate the return and ZERO restocking fee. There are a multitude of reasons our customers would want to take advantage of our 30 day guarantee and we make it a simple transaction if you need to take advantage of it too. Testing is one reason a customer would use this 30 days, other customers may have ordered incorrectly or released product inadvertently, they may have wanted a small sample for a meeting or demonstration at a customers location.

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.

If you would like to talk about Industrial Housekeeping products or any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

Simplifying Plastics Machining Using The Cold Gun And Chip Vac

I was recently contacted by a plastics manufacturer who was needing some solutions for problem areas in their production processes. The company imports their machines from overseas and they are outfitted with a coolant based, quench system for the tooling. They were wanting to get away from using coolant as the parts were absorbing liquid, causing them to swell, not to mention the mess they were creating, requiring more time and labor to dry and clean the parts manually.

For the first application, replacing the messy misting system, I recommended the customer use our Cold Gun System, Model # 5215. The Cold Gun uses Vortex Tube technology to produce a cold air stream 50°F lower than the incoming compressed air supply temperature. For example, if your supply air was ambient 70°F, you would effectively see 20°F air at the exhaust. This clean, cold air stream can be easily directed to the needed area to prevent any warping or other damage related to heat, while also blowing away the machined fines.

Model # 5215 – includes the Cold Gun, Single Point Hose Kit, 3/8″ Cone Nozzle, 1-1/4″ Fan Nozzle and Filter Separator

The second part of the process involved the recovery of the plastic scrap and chips created during the machining process. Once again, EXAIR has the ideal solution with our Chip Vac, Industrial Vacuum. The Chip Vac creates a powerful vacuum, with no moving parts or motors to wear out, making them virtually maintenance free. The Chip Vac is designed to vacuum dry or wet chips and collect them in a standard, open-top steel drum. Systems are available in 5, 30, 55 or 110 gallon capacities.

From small area clean up to larger scale processes, the Chip Vac has you covered

To discuss how EXAIR products might help improve your machining process, give us a call at 800-903-9247.

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.

If you have questions regarding E-Vac Vacuum Generators or any EXAIR Intelligent Compressed Air® Product, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
