Reversible Drum Vac Empties Sumps For Demolition Company

A demolition company was looking for a way to remove the liquid from sumps and tanks in the industrial buildings they were contracted to provide their service upon. The liquids in question were mainly coolant and oil that had been left behind when the machinery was removed…anything that could be re-used was already gone; this was the “bitter dregs,” as it were.  Since these buildings are about to be demolished, electricity is rarely available.

They had a pumping system that ran off a diesel engine that they COULD take with them, but they ALWAYS had a large mobile air compressor for the pneumatic tools used in other processes in the demolition of the building. Since they had steel drums in abundance, the Reversible Drum Vac Systems sounded very attractive to them, so they got a Model 6295 Deluxe High Lift Reversible Drum Vac System for 55 Gallon Drum to try out.

The High Lift Reversible Drum Vac System converts a drum and dolly into a mobile pumping system.

Now, instead of committing an additional truck (and driver) to getting the diesel engine driven pumping system to the site, they simply move the Reversible Drum Vac pump unit from 55 gallon drum to 55 gallon drum as they’re filled. Once the drums are returned to their facility, they switch the the Reversible Drum Vac to the “empty drum” configuration, and use it to pump the liquid out into their recycling tanks, where they await collection and processing by their waste handling service.  Even when they have to use a number of drums, the High Lift Reversible Drum Vac Systems still streamline the process over the use of the diesel engine pumping system.

If you’d like to find out more about our Industrial Vacuums, or any of our compressed air operated products, give me a call.

E-Vac For Lubricant Recovery

Over the last 3 months, I have been in contact with a customer, keeping track of an application that involved the EXAIR E-Vac.  The customer had reached out to us looking for some advice on how to solve a process problem. The operation is a drawing/stamping process, and the when the part exits the machine there is coolant that resides in a deep draw section, approx 0.4″ in diameter by 3.5″deep.  About 1 oz of coolant per part is retained, and over many 1000’s of parts, would add up to lost dollars and messy clean up.

The customer was looking for an automated process that would be able to draw out the coolant and direct the liquid back to the coolant reservoir, all while maintaining the current machine run rate. We settled in on the model 840015 Adjustable E-Vac Generator. The Adjustable E-Vac has a straight through pathway from suction through to discharge, allowing for fast evacuation times.  A simple turn of the unit changes the vacuum and flow levels to best match the needs of the application.  The Adjustable E-Vac coupled to a solenoid valve controlled by the stamping machine resulted in the automatic system the customer was looking for.

The customer ordered a unit, and based on the preliminary bench testing, it was approved for a production run trial. After some tweaking in the production environment, the unit was performing to spec, and was then subjected to a 100,000+ part run.  The results were a success!  Instead of the parts exiting onto an inclined conveyor, relying on gravity to drain and causing coolant to collect under the conveyor, the coolant could be removed in a controlled manner and sent back to the reservoir.  Less mess and no coolant loss.

EXAIR manufactures (3) types of E-Vacs – Low vacuum generators for porous materials, high vacuum generators for non-porous materials, and the adjustable type for flexible vacuum performance.  They are available in multiple sizes, to best match the vacuum requirements, while using the least amount of compressed air.

To discuss your application and how the EXAIR E-VAC can benefit your process, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

Celebrating The Chip Trapper

NFL Football season is officially under way, and my hometown team, the Cincinnati Bengals, are off to a solid start. With less than a minute left in the game on Sunday afternoon, an interception stopped the New York Jets’ final drive, and Who-Dey Nation began to celebrate the win. Some (not me…not as far as you know) may have even celebrated in accordance with a hallowed Bengals tradition:

While I won’t celebrate just ANYTHING (although I do indeed hold prompt service at the deli counter in high regard,) you might get me excited enough to do the Ickey Shuffle if you start talking about how much you like your Chip Trapper.  Just like a caller did this morning.

Now, I’m unabashedly proud of all of our products, so I’m not going to come right out and SAY that I have a favorite any more than I would publicly proclaim one of my children as my favorite.  Although, in all fairness, they’re teenage boys, so at any given time, one of them is quite likely edging out the other on The List.

But back to the Chip Trapper – this morning’s caller just wanted to order some more Filter Bags, but in the midst of our conversation, he started “writing the commercial” for the product:

*It’s extended the life of their coolant – regular removal of solids and particulate contamination means the coolant stays clean & effective.

*It ensures the reliability of the machine – clean coolant doesn’t clog the lines, which WILL wreck the part you’re machining, and probably the tooling too.

*It eliminates odors – OK; nobody ever brags about a “spring fresh” aroma in a machine shop, but bacteria-laden, rancid coolant is the WORST.  Nobody needs to be working around that.  And since that bacteria needs solid surfaces to grow on, filtered coolant is fresh coolant.

*It’s EASY (part 1) – it’ll pump 55 gallons of dirty coolant into the drum in about 90 seconds.  Turn the valve and reverse the direction of the Reversible Drum Vac, and it’ll pump freshly filtered coolant back into the sump just as quickly.

*It’s EASY (part 2) – the Filter Bag holds over 5 gallons (almost 3/4 of a cubic foot) of chips, and the system comes with two of them so you can use one while cleaning out the other.

EXAIR's new Chip Trapper
EXAIR’s Chip Trapper comes in 30, 55, or 110 Gallon Sizes, depending on your needs.

If you’ve got a machine shop and DON’T have a Chip Trapper (yet,) call me; let’s talk.  If you DO have a Chip Trapper and you like it as much as my caller today did, DEFINITELY give me a call.  I might even do the Ickey Shuffle with you.

Being a Manufacturer Who Improves Manufacturing Has Benefits – For You

On many of occasions EXAIR has benefitted from our own products. One of the fertile areas for testing, product development, and customer feedback are our own manufacturing and assembly processes. Yes, EXAIR is a real factory in Ohio with employees, machinery, and equipment that uses our products everyday. Being a production facility leaves us best suited to understand the abilities, challenges, and opportunities of our customers. Today, I want to point out how two of our products have helped us to make Intelligent Compressed Air products that exceed your expectations. The Ultrasonic Leak Detector and Chip Trapper have both been studied at our facility to measure and understand the real benefits and capabilities of our products for our customers. Below is their story.

Leak Detector
Ultrasonic Leak Detector, Model 9061


Famously, one of the original case studies for our Ultrasonic Leak Detector took place at 11510 Goldcoast Dr Cincinnati, OH. (That’s EXAIR Corporation’s address). As the biggest rival against wasted compressed air, having it at EXAIR would be inconsistent with our own philosophy – we just can’t have it. Our President, Bryan Peters wrote about the benefits of the Ultrasonic Leak Detector in a blog “Free Money!…”. In the blog, he details the mystery of the compressed air costs during times when our plant was not running. Compressed air was so expensive that was costing us money while we were closed. Using the ultrasonic leak detector, EXAIR was able to find our leaks and fix them. The leaks in our system were miniscule compared to some old and very large compressed air systems. But even with our relatively small leaks we were able to save ONE MILLION CF per year of compressed air. This lost compressed air results in significant energy consumption as your compressors try to keep up with the demand caused by the leaky air lines. Please stop wasting money and energy on compressed air leaks. Find them today with EXAIR Ultrasonic Leak Detector.

At EXAIR, we also deal with a  variety of metalworking coolants as we manufacture aluminum, brass, and stainless steel parts. Before we started using our Chip Trapper, our water based coolant would last around 2 months. After those six weeks, we would vacuum out the coolant. After the coolant is pumped out, we would then shovel out the chips that had settled in the bottom of the sump. This task is time consuming, and the smell is awful from the rancid coolant. We found that by using a Chip Trapper weekly. We could extend our coolant life to six months. Some may say that cleaning the coolant sumps weekly is adding work. That is an old mentality though because by removing chips from the coolant weekly we save hours of labor we used to consume every two months and clean up our coolant in minutes not hours.  Here is a video to learn more. Our machinists loved our final prototype so much they kept it. You know how machinists are. Don’t mess with their tools.

Life Hacking = Better Easier Life. So What Happens When You Hack Compressed Air?

The birth of the internet and personal computer brought to light a new form of hacking.  For many years now hacking has been considered a negative action, even criminal.  However, within the past several years the term lifehacking has come to mean a process of bettering your life through tips and tricks.  There are entire blogs and TED talks about life hacking, so that has gotten me thinking of how can EXAIR hack your compressed air system and turn it into a life hack?

All of our products are designed and engineered to make your life easier and better.  The best product I can think of to demonstrate this is our Super Air Knife With Plumbing Kit Installed.  This is an option for any of our Super Air Knives which are longer than 24″ that makes installation even easier on your end.  The plumbing kit has already connected air to each port on the Super Air Knife so all you have to do is plumb air to a single port at the end of the kit assembly.  See the picture below for a better idea.

Another item that has helped many customers is our Chip Trapper System.   This is essentially a modified or hacked Reversible Drum Vac System which  adds the benefit of filtering the liquid you are sucking up to a 5 micron level.  (Other filter levels/sizes available.) This means you can make your cutting fluid last longer and cut that rancid coolant smell in your machine shop down because the bacteria in the coolant doesn’t have any solids to live upon.  This also means that you won’t be giving your coolant reclamation company any of your valuable solids so you keep more of your scrap profits.

So if you are looking for a way to make your life easier while you are working with compressed air, let us know, we’ll see how you can hack your compressed air applications.

What Else Do I Need?

This question comes up a good amount when a customer calls in and asks about an EXAIR Product.   What else do I need in order to get this thing up and running.   It will depend some on the application the customer is trying to solve and some on the equipment the customer may (or may not) have in house, and some on how convenient and easy the customer would like to make the whole process. Let us look at the Industrial Housekeeping products, more specifically the Reversible Drum Vac Systems. (Mainly because this is the most recent product I have had a customer ask what else he needs to buy.)

The customer had already chosen a 55 gallon system (other systems available include a 30 and 110 gallon). When we look at the three different 55 gallon systems we offer, there is a clear difference in the number of items included in each kit.  The #6196 is a basic Reversible Drum Vac Kit.  For a unit like this, all you need to do is to provide a compressed air source and a tightly sealed 55 gallon steel drum. The picture below will show each item that is included in the kit.


If you are worried about some liquid spills on the floor and you would like to get some extra pick up tools and a dolly for the steel drum you are providing, then the #6296 Deluxe Reversible Drum Vac System is for you.   It will include everything from the basic system plus, a drum dolly, Spill Recovery Kit, magnetic tool holder, and extra plastic tools.  Again, the only items you will need to supply are the air compressor, and the tightly sealed 55 gallon drum.


The final solution that EXAIR offers is everything you need, the whole kit and caboodle if you will. This kit prevents sourcing compressed air supply line and a closed top drum. It’s all in the box – with the exception of an air compressor. In the #6396 Premium Reversible Drum Vac System you will received the drum, everything in the Deluxe Kit, but some of the tools that were plastic get upgraded to aluminum tools.   This gives you the complete solution with a few clicks on our website.


Throughout all of our product lines we give you the option to choose the best solution and most convenient package to get the problem solved quickly. We hold stock on all of our products (and accessories) so we can ship same day when we receive an order by 3:00 pm est.  We have the necessary accessories for you to get our units in and simply plug them in to your compressed air supply.  Why go to multiple sites or vendors when they are all in one place.

Continuous Improvement

I’m sure I have blogged about similar topics before but I’m going ahead with this anyway.   Have you ever bought something and after using it a few times say to yourself, I really wish they would have done this or I wish this had this feature.  I do that quite often, more often that my wife really cares for.  Normally it ends up with me being in the garage or the basement working on whatever it is for several hours and possibly even breaking whatever it was I was working on.  Well, I don’t just do that at home.

Two of our newest Industrial Housekeeping products were created from our own employees using them and seeing something that could make it better.   The easiest to see this with is our Chip Trapper System.


Our Reversible Drum Vac Systems were around for a couple decades when someone decided to figure out a (patented) way to filter all the chips and solids out of the coolant we were processing.  So now, instead of just sucking the coolant out, we are able to filter the coolant and reuse it up to four times longer in our machines.

It is continuous improvements and being willing to listen to recommendations that make things like the Chip Trapper possible.  If you have one of our products and see a better idea, feel free to let us know, it may even be something that we could do on a custom basis for you.
