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 # 6195, 6195-30 and 6195-110

Deluxe Systems include all of the items shown above in the “Standard” System and adds a drum dolly, ABS plastic spill recovery kit, (2) extension wands, crevice tool, skimmer tool and a magnetic tool holder.

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.

30 day money back guarantee

Order An Industrial Vacuum System Through 5/31/18 And Receive A Free Vac-u-Gun

From now through May 31, 2018, we are offering a FREE Vac-u-Gun with any order for one of our Industrial Housekeeping Vacuum Systems. The Vac-u-Gun is a multi-purpose tool that can be used to vacuum or transfer material from one location to another or it can be used as a powerful blow gun to clean debris off of the surface of a part or workstation. There is no electricity required to operate and no moving parts to wear out, providing for a safe, maintenance free operation.

Change from a vacuum gun to a blow gun in a matter of seconds!

When choosing one of our vacuums, selection can be simplified depending on what type of media you are needing to pickup. Our systems are going to be either solids handling or liquid handling.

Our Chip Vac Systems are the ideal choice when looking to vacuum dry or damp debris left over from machining operations and delivers them to a standard open top steel drum. For more abrasive material, such as sand or steel shot used in sandblasting processes, the Heavy Duty Dry Vac provides superior wear resistance due to it’s proprietary hardened alloy construction.

If you are looking to vacuum liquids we offer our Reversible Drum Vac and High LIft Reversible Drum Vac providing higher suction lift, up to 180″ H2O.

Our Chip Trapper and High Lift Chip Trapper are also used in liquid applications but these systems incorporate a filter bag inside the drum to capture any suspended solids in the liquid so only clean fluid is pumped back into the reservoir or tank.

In dusty applications we offer the Heavy Duty HEPA Vac which uses the same vacuum as the HD Dry Vac but this system provides a higher level of filtration meeting HEPA requirements of 99.97% filtration at the 0.3 micron level.

All of these products are In-Stock, Ready To Ship.

To take advantage of the offer, you need to order using the promotional Model number. Ordering is easy – you can email the order to orders@exair.com or place your order online at www.EXAIR.com. If you’d rather place your order over the phone or have any technical questions about our products, you can call us at 800-903-9247 and one of our reps will be happy to assist.

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

EXAIR Mini Chip Vac: Phase 2 for Improving Medical Devices

Medical Anatomy

In my previous blog about the manufacturing facility that machined small plastic components for the medical industry, I explained how the Stay Set Ion Air Jet Kit was able to improve the machining process by eliminating static.  (You can read the blog here: EXAIR Ion Air Jets: Phase 1 for improving medical devices).  With their machining center being in a semi-clean room, cleanliness was very important.  So, after each machining operation, they would have to sweep the plastic chips from the machining table and discard.  This extended the cycle time in their machining operation.

Since they had such a great relationship with EXAIR in dealing with their previous application, they contacted us again to improve their cleanup operation.  Non-conductive materials like plastic generates static on the surface when the material is peeled, shifted, or rubbed against another surface.  Since we removed the static from the plastic shavings with the Stay Set Ion Air Jet, we wanted to target that area before static could regenerate and start “sticking” to clean parts.  In getting more details about their setup, they were machining with vertical CNC mills.  The mills had a platform table that had a pneumatic fixture to grab the medical part.  Before machining began, the operators would have to close Plexiglas doors as a safety requirement.  The CNC mills did have an opening at the top of the machine.  (This was where they were supplying the Stay Set Ion Air Jet with compressed air and power supply.)

Mini Chip Vac

With my experience, I had a good suggestion for refining their cleaning operation.  I suggested the model 6193-5 Mini Chip Vac System.  This system uses compressed air to generate a vacuum for picking up chips.  The vacuum generator does not have any moving parts or bearings to wear; so, they are very durable and long-lasting.  The Mini Chip Vac System uses a 5 gallon drum which is very compact and easy to use in tight areas.  The system includes a 0.1 micron filter to keep all the contamination inside the drum and not allowing it to escape back into the room air.  (Very necessary in a semi-clean location.)  Even for its small size, the Mini Chip Vac is very powerful and quiet.  It has a decibel rating of only 77 dBA; so, noise will not be a nuisance when operating the vacuum.  It comes standard with a 10 foot vacuum hose which make it easy to reach into tight areas to clean.

As a suggestion, I recommended that they could collect the plastic shaving during the machining process Instead of waiting until after the operation to clean.  They could mount the Mini Chip Vac drum near the machine, and bring in the vacuum hose through the opening at the top.  The suction end of the vacuum could be placed on the opposite side of the Stay Set Ion Air Jet.  In conjunction, the Stay Set Ion Air Jet would remove the static and swarf from the plastic surface; at the same time, the Mini Chip Vac would collect and remove the plastic shavings from the machining area.  This combination of EXAIR products would keep the parts clean as well as the machining area.  When they installed the Mini Chip Vac System into their process, they almost doubled their production rate.

If you are dealing with messy chips in your machining operation, the EXAIR Chip Vac Systems can be a solution for you.  For the customer above, I was able to find a simple way to use the Mini Chip Vac to keep the area clean and increase their production rates.  If you are spending too much time in cleaning up your area, you can contact an Application Engineer to find the best solution to streamline your operation.

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.
