Reduce, Reuse, Recycle

I think we have all heard the mantra Reduce, Reuse, Recycle – a phrase that is thought to have originated back in 70’s when environmental protection became a governmental policy.

We at EXAIR can help your company follow this important principle and help to keep your costs down as well.

Reduce – Reduce the number of times you change out your coolant, reduce your wastewater. Our Reversible Drum VAcs and Chip Trappers help keep your coolant clean by providing a simple and effective method to remove and/or strain your coolant.

Also, remember this – they are VERY hard to break or ruin. If you have one of our liquid handling Reversible Drum Vacs or Chip Trapper units, and the performance isn’t quite as you remember it to be, give us a call.   We can help to trouble shoot and narrow in on the root cause.  Most of the time, it is a simple fix, such as a air leak or a change to the air supply system that has caused a drop in performance. If we have eliminated all of those possible causes, we can offer the RDVREFURB option. Simply send in your Reversible Drum Vac pump unit, and we will do a free evaluation. Then we’ll let you know what we find, and provide a quote for the repair.  The repair typically involves a thorough cleaning, replacement of a few basic parts, and then setting and testing to original factory specification.  Because the unit has no moving parts, there isn’t much that can break down or go wrong.  Don’t throw away that unit, REDUCE the amount of waste you create.

Reuse – Maybe you have a Super Air Knife in storage that is not in use, and you come up with a need, but the Knife doesn’t quite match the application.  We can provide new custom shim to change the air flow pattern.  Perhaps you have a 24″ Super Air Knife, but the new application requires only 18″ of airflow.  You can send the knife in and we can clean it up and install a new custom shim to provide the exact airflow pattern that meets your requirements.  Or, we can send the new shim directly to you for your team to install. Don’t let the unused product lie around, REUSE it for another process or application.

Recycle – If for what ever reason a product has been deemed to be no-longer viable and cannot be reused, the time comes to dispose of it.  We hope that you would take the time to recycle it properly. With materials of construction including brass, aluminum and type 303 and type 316 stainless steels, most EXAIR products can be RECYCLED as common metals and you may even get a little money back!

To discuss your processes and how an EXAIR Intelligent Compressed Air Product can provide a beneficial service, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

If at First You Don’t Succeed Try, Try Again!

Over the past few weeks I’ve been going back and forth with my phone provider over some technical issues I’ve been having with the device. After some troubleshooting, we were able to conclude that the antenna has likely become loose, leading to the phone periodically not receiving service. Naturally, we’re outside of the 1-Year “Warranty” period that covers a defective device. I paid my insurance deductible and received a “refurbished” phone the following day. Unfortunately, this refurbished phone was unable to take pictures with the front-facing camera. I know what you’re thinking, how on Earth can I take selfies without a front-facing camera? So it was back to the phone provider to get another replacement, fortunately this time they sent a brand new device.

There’s nothing more frustrating than trying to get something to work right out of the box, only to experience issues. Whenever a customer is having an issue with a particular product, there’s a certain progression that we go through in order to assess the problem and determine the root cause. In some cases it is something simple, others it can be a few individual problems that are compounding each other. I recently assisted a customer that was having problems with his 110 Gallon Reversible Drum Vac System. He was having difficulty pumping water out of a container and into the 110 gallon drum. He stated that he just received the unit and was unable to get it to work.

This is a call that we get from time to time, and is generally remedied pretty quickly. Our first step is to check the air pressure at the inlet of the Reversible Drum Vac while it is operating. We recommend an inlet pressure of at least 80 PSIG for proper operation. By installing a pipe tee with a pressure gauge directly at the unit, we can not only verify the inlet pressure but also that the Reversible Drum Vac is being supplied with an adequate volume of compressed air. If the pressure on the gauge begins to decrease once the unit is in operation, we can conclude that the volume of compressed air to the Reversible Drum Vac is insufficient. This can be due to the use of restrictive quick disconnect fittings, improper line size, or a compressor that is undersized.

If the air supply is sufficient, we then inspect the system for vacuum leaks. If the drum does not have a complete seal, the system will not function. If there’s no vacuum leak and there is an adequate supply of compressed air, the Reversible Drum Vac likely needs to be cleaned. It took us a few tries to get there but through a little bit of trial and error, we were able to determine that this was exactly the case in this scenario. Even though the system was new, it had been supplied with compressed air that was not properly filtered. Some scale, rust and debris from the customer’s supply lines made its way into the body of the Reversible Drum Vac, impeding the flow of air. Here is a video that shows the cleaning procedure for the Reversible Drum Vac. Over time the Reversible Drum Vac can accumulate debris inside of the plenum chamber. Regular maintenance of the unit will ensure that it stays within specifications for when it’s needed most!

If you have an EXAIR product that’s not performing as well as it used to, give us a call. One of the Application Engineers will be able to walk you through the steps to ensure that you’re getting the most out of our products!

Condiment Sauce Recovery Using The High Lift Reversible Drum Vac

Last week I worked with a food manufacturer who makes a line of specialty sauces, with consistencies similar to BBQ sauce or ketchup, who was looking to vacuum spills off their production floors. During production, they will sometimes experience an overfill during the bottling process, which results in the product spilling on the floor. Their current clean up method is to have an operator with a wash down hose, “thin” the sauce spills with water then direct it to a drain in the floor so it can be sent to the scrap tank. This was causing a few issues though, first, the drains have filter traps that were clogging regularly from not only the sauces but other particulate that may have been on the floor, causing environmental concerns for the plant. The other concern was the amount of water they were wasting to perform the clean up. My contact was the newly appointed maintenance manager and was tasked with trying to find a more reliable, economical way to remedy the situation. He was familiar with EXAIR as he had used some of our Line Vac Conveyors at his previous employer and knew we also carried a line of Industrial Vacuums but was unsure which product would be best suited for his needs so he reached out for assistance.

After discussing the details of the application, I recommended he use our High Lift Reversible Drum Vac System. The High Lift RDV is a liquid only vacuum that provides 180″ H20 vacuum and is able to handle thicker, more viscous fluids (up to 1400 cP) than our standard Reversible Drum Vac. With the ability to vacuum liquid up to 15′, the unit comes standard with a 20′ flexible vacuum hose and has no motors or moving parts to wear out. The system quickly installs to a standard closed head steel drum with available capacities of 30, 55 or 110 gallons. For spills, we offer our optional Model # 6901 Spill Recovery Kit which includes a 54″ ABS wand and 14″ double-blade squeegee that makes floor cleanup a breeze. After the material has been vacuumed, the unit can then be set to “empty” to pump the liquid back out to their waste tank so it can be carried away by their environmental recovery supplier.

The High Lift Reversible Drum Vac is able to pump thicker liquids from sumps or tanks up to 15 feet deep.

Contaminated Air Supply Leads To Unwanted Results

IMG_5570

Rust from the air supply found inside a compressed a Reversible Drum Vac.

One of the greatest attributes of EXAIR products is their ability to stay in operation for years on end without any maintenance.  With no moving parts to wear out, there really is little-to-no upkeep required.  So, when we receive notice from a customer that an EXAIR product is not working properly, we most always seek to establish the pressure, volume, and quality of the compressed air supply.  By examining these three variables, we can usually pinpoint the source of the performance discrepancy.

I had an exercise in this routine a few days ago with a Reversible Drum Vac (RDV).  The RDV had arrived at EXAIR after the customer noticed a drop in performance.  The RDV went from operating normally to gradually loosing strong vacuum when vacuuming liquids out of a coolant sump.

The end user and I discussed the air supply pressure, line size, and available volume of compressed air to operate the RDV which all seemed to be in order.  Compressed air supply pressure was 80 PSIG, they were using the EXAIR supplied (properly sized for the product) compressed air hose, and the unit had functioned in this exact setup for some time, so we were confident in the ability of the compressed air system to supply adequate volume.

In most cases, when an RDV gradually loses vacuum, or experiences a change in performance without a change in application parameters, contaminants from the compressed air system can be found inside of the RDV.  And, that is exactly what happened here.

I first tested the RDV for vacuum level and flow, both of which were low.  When I disassembled the RDV I noticed what looked like rust on all surfaces which are in contact with the compressed air stream (photo above).

Internals of the Reversible Drum Vac “body”; littered with rust

Then, I peered into the body of the drum vac and saw the root of the problem – dirt and rust from the compressed air system had accumulated within the RDV, restricting compressed air flow and causing the decay in performance.

After a quick cleaning of the RDV, performance was perfect and the RDV was ready to go back into operation.  The end user and I discussed my findings along with proper air filtration to prevent a similar occurrence in the future.  They were glad to know their RDV was in working order, and we were both glad to confirm the root cause.  With a new filter separator installed at the compressed air line feeding this RDV, trouble-free and maintenance-free performance can be expected for a long time to come.

If you have a similar application need, or think an EXAIR solution may benefit your process, contact an EXAIR Application Engineer.

“Deluxe” and “Premium”

These are two words that have been important parts of my vocabulary for most of my life. As a long time fast-food burger connoisseur, these words mean I’m getting something other than a hastily cooked ground beef patty on an enriched white flour bun that may or may not have been sitting under a heat lamp for a specific period of time. If you’re anywhere near as familiar with drive-thru cuisine as I am, you’ll know that “Deluxe” usually means a variety of toppings has been added to an otherwise relatively plain sandwich…it’s been “run through the garden,” if you will. And “Premium” can mean anything from a special bun, gourmet cheese, up-scale meat, and/or the addition of bacon…they ALWAYS get me at bacon…

I don't know what the knife and fork are doing there, but whatever...

I don’t know what the knife and fork are doing there, but whatever…

EXAIR’s Industrial Vacuums are also available in Deluxe and Premium Kits. Now, if you’ve already got a drum, our standard Kits will quickly and economically turn that drum into a powerful, fast, and efficient vacuum system, without the need for anything fancy. If you’re looking for complete, comprehensive clean up solutions, though, our Deluxe Kits add a drum dolly, a tool holder, and additional tools. The Premium Kits also include a durable steel drum and a set of Heavy Duty Aluminum Tools.

Whatever your needs are, we’ve got an efficient, quiet, durable, long-lasting, maintenance-free vacuum system for you. Our Reversible Drum Vac will empty…or fill…a 55 gallon drum in 90 seconds (tested with water.) Our new High Lift Reversible Drum Vac pumps that same 55 gallons in just 85 seconds, with up to 15 feet of suction head. Then, of course, the Chip Trapper uses our Reversible Drum Vac technology to filter and extend the life of your machine tool coolants, lubricating oils, etc.

For solids vacuuming situations, our Chip Vac picks up wet or dry chips, debris, etc., and deposits them directly into the drum. This is the function of the Heavy Duty Dry Vac as well. It’s more powerful than the Chip Vac, for use with heavier debris, and it’s made of a hardened alloy for superior abrasion resistance. The Heavy Duty HEPA Vac delivers the same high performance, with a high efficiency filter for total dust containment.

What You Can Get Used To, Revisited

I just got a new pair of glasses. My existing pair was fifteen years old…it had also been that long since I had been to the ophthalmologist. Which is a shame, because my health coverage includes an eye exam every year. That’s a subject for another time, though. Today, I want to talk (again) about what you can get used to (if you allow yourself,) and what I HOPE I can get used to.

 

It shouldn’t be hard to believe, but my eyesight has changed a bit since my mid-thirties, when I got my last pair of glasses. I’d been noticing for some time that I had to take off my glasses to read small print, and some of that was getting too small to read if the light wasn’t just right. I got used to taking things into another, better-lit area in those cases. My new glasses have changed all that, making me think that I should have done this a few years ago. I’m committed to having my eyes checked on an annual basis now, and I encourage you, dear reader, to do the same, especially if your health plan covers any part of it.

I had the pleasure of talking to a Chip Trapper user recently – they’ve had our system in their shop for almost five years, and I got the call because it had lost its suction, and they wanted to purchase a new pump unit (Reversible Drum Vac or RDV) for it.

This is a fairly regular call for us. It’s a situation that is usually very easily remedied by a simple cleaning of the RDV unit itself. In fact, it’s so common that Brian Farno’s RDV Cleaning & Rebuild Video is our most popular Video Blog (even beating out the Professor Penurious series, if you can believe that.)

Once they had watched the video, they dove in to their RDV. Once it was restored to operation, my new friend called me to express amazement at how well it was working…it seems that the performance had degraded over time, and, week in/week out, they had simply gotten used to it taking a little longer to draw the coolant out of their sump. They’ve now incorporated the RDV cleaning ritual into their planned maintenance schedule…something else they’re already used to.

Another thing I’m having to get used to is the ribbing I’m taking for my new glasses. See, they’re my first pair of bifocals. Which brings me to my parting advice for today: Don’t get old if you can help it. Especially if you’ve got friends like mine.
