The Trusty Reversible Drum Vac, 16 Years Later

This week a customer sent us a Reversible Drum Vac to refurbish. From time to time a Reversible Drum Vac may need (depending on cleanliness of the supply air) cleaning due to particulate from the compressed air line landing inside the air chamber of the Reversible Drum Vac. EXAIR regularly rebuilds, cleans and tests Reversible Drum Vacs that customers send in to have us return them to new condition. You can also easily refurbish the Drum Vac at your facility: Here is a link to our How-To video for cleaning your Reversible Drum Vac. This particular Reversible Drum Vac though was clearly special.

16 Year Old Laser Marked Reversible Drum Vac

At first glance, the Reversible Drum Vac had been laser marked by the customer to permanently label their unit. The customer just so happened to be a laser marking shop, so I’m sure it was convenient for them. But digging deeper, the company originally purchased the unit in 1999, this Reversible Drum Vac could get its Learner’s Permit in most states. During the 16 years our customer was using the Reversible Drum Vac, we never heard from them. After 16 years they contacted us but not for a problem. They just wanted us to clean and inspect the unit to ensure maximum efficiency. This unit, though a bit dirty, was still operating very well. EXAIR put it through our refurbish process and brought it back to performance specifications that matched a new product.

The Reversible Drum Vac is a compressed air operated vacuum that attaches to a 55 gallon drum to create a vacuum that can also empty a 55 gallon drum in 90 seconds. The Reversible Drum Vac pulls a vacuum on the drum creating a siphon the pulls the liquid into the drum. With this technology the liquid never pass through the Reversible Drum Vac, which leads to its tremendous longevity. It is the perfect vacuum to empty coolant sumps, isolate contaminated liquids, or clean floor spills. The Reversible Drum Vac have no motors to wear out or impellers to clog so they last longer than their electrically operated counterparts.

Heavy Duty Dry Vac is a Perfect Fit for This Application

A milling company contacted me for help to improve their scrapping operations.  They had 8 machining stations that were used to machine cast iron.  The chips were removed from the machines by a conveying system and dumped into a wheel barrel next to each machine.  Throughout the day, the CNC operator would have to remove the wheel barrel to the scrap recycling area.  The operator would then shovel the chips from the wheel barrel into 55 gallon drums for storage.  The company had concerns with safety ergonomics, and they wanted to improve the efficiency of the operation.

I suggested the Heavy Duty Dry Vac.  The vacuum generator is made from a hardened steel construction which is very resistant to wear.  It has a higher vacuum level to pick up heavier material at a faster rate.  With the cast iron chips having a bulk density between 130 – 200 lb/ft^3 (2082 – 3204 Kg/m^3), this was the right tool for the right application.  He purchased the model 6297, the Deluxe Heavy Duty Dry Vac System.  It included the 55 gallon lid vacuum system, heavy duty aluminum tools, drum dolly, 10 foot (3 meter) anti-static vacuum hose, and 20 foot (6.1 meter) compressed air hose.  Now, with their new product and new procedure, the CNC operator was able to place the Heavy Duty Dry Vac lid system onto a 55 gallon open drum, turn the unit on, and vacuum the cast iron chips from the wheel barrel.  Once the drum was full, he could swap lids to an empty drum to repeat the operation.

EXAIR was able to address both concerns.  It was faster, saving them down time and improving operation efficiency; and, it was safer, eliminating the need to shovel and improving health ergonomics.  Because of the wide range of products that EXAIR offers, we can help you with saving money and overall safety.  If you would like to discuss any of your issues with our Application Engineers, you can contact us at your convenience.

FREE Vac-U-Gun Offer!

A couple weeks ago I wrote a blog titled, Spring Cleaning All Around, outlining just a few of the many  features of our Industrial Housekeeping Products. All of these products are compressed air operated, have no moving parts and require no electricity, making them a safe and virtually maintenance free option for industrial clean up.

We are currently running a promotional offer, where if you purchase one of these products by May 31, 2015, we will include a FREE Vac-U-Gun, a $98 Value!!! (Use the promotional model number within the promo to receive the offer).

Vac-U-Gun Promo

Just click the photo for the promotional Model #

The Vac-u-Gun can be used as a blow gun, vacuum or for product transfer. Using only 13 SCFM @ 80 PSIG of compressed air, the unit produces a high output airflow on one end and creates a vacuum on the other end. In blow off mode, the unit provides 9 ounces of high velocity, forceful airflow. By changing the orientation of the nozzle insert, the unit can be converted into vacuum mode, producing -29.5″ H20 vacuum, use the bag attachment for general clean up. The output end can be connected to an 1-1/4″ smooth bore hose, allowing for the transferring of dry media. Again, there are no moving parts or electricity required to operate, so you get the convenience of 3 separate tools all in one single, safe hand held device!

Vac-u-Gun orientation

Simply change the nozzle insert orientation to quickly change between blowoff mode or vacuum mode.

Of course, if you need any assistance with selecting the right Industrial Housekeeping Product, you can always contact an 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.

Whatever your Industrial Vacuum needs are, we’ve got a solution for you. And if you order before the end of March, we’ll throw in a FREE Vac-u-Gun…our lightweight and portable vacuum gun, blow gun, and transfer tool, all in one. Call me to find out more.

The HEPA Filter Protector

With our Heavy Duty HEPA Vac, it is very capable of capturing particles that are very small. You do not have to worry about re-entraining the dirt that you vacuumed back into the air. The filtration efficiency of the HEPA filter is 99.97% at 0.3 micron. Because it is so efficient, we place a prefilter on the outside of the element. This helps to capture the larger particles so that they do not prematurely plug the HEPA media. In extreme conditions with large amounts of debris, we do have another option. It is the model 901373 filter protector. It is a bag that will go on the outside of the prefilter and the HEPA filter. With a large influx of contamination, the filter protector will create a matrix from the contamination to create a cake. This cake, as it builds, will start to capture smaller particles and become more efficient. It is similar to a natural dam after a big rain. The large boulders and logs collect into a section, and then the smaller rocks and branches will collect behind it.

Under normal conditions, the standard HEPA filter with prefilter will last you for a while before replacing. It is dependent on the amount of dirt that is being collected. But, in those extreme conditions, you do not want to change the HEPA filter every week. This would be too expensive. That is why EXAIR found a cost-effective option to help, the filter protector. The model 901373 filter protector can be changed in a matter of minutes and the cost is less than 2% of the HEPA filter. Just like disposable shoe covers, they are inexpensive and they protect your expensive shoes. If you require any more information on our Heavy Duty HEPA Vac or the accessories, you can contact one of our helpful Application Engineers at EXAIR.

Guess What Today Is?

Well, if everything went as planned, this blog is actually being posted on Friday. However, I’m writing it on Wednesday.

Don't even think about saying it.

Don’t even think about saying it.

Our daily blogs are written a couple of days in advance, so that they can be reviewed. None of us ever draft anything that’s inappropriate. Not REALLY inappropriate, anyway…but they are indeed checked for grammar, content, accuracy, and quality. I’m probably the most conceited about my writing ability (and for good reason…see?) but I’m still humble enough to appreciate any suggestions for improvement. Heck, if they make it look better before anyone else sees it, I get to take credit for that, too. It’s not like you readers know what gets changed.  If you want to know what I’m like sans edit review, you can always follow me on Twitter.

If our system of blog review and posting proves anything, it’s that it never hurts to run your plan by someone else with experience in what you’re trying to do. Case in point:

I had the pleasure of discussing an Industrial Vacuum application with a customer recently. One of our Chip Vacs had been in use within their shop for a long time, and they were quite pleased with its durability and longevity. They had begun working with some hardened steel product a while back, and, over time, those chips & shavings had worn through the Chip Vac’s aluminum body.  They wanted to order a replacement Chip Vac unit, and perhaps keep another in stock for when that one wore out, and were simply calling for price and availability.

Our solution, instead, was to provide a Heavy Duty Dry Vac. They didn’t need the complete system; just the Model 6097 Heavy Duty Dry Vac unit itself, since it’s dimensionally identical to the Chip Vac. They just unscrewed the Chip Vac on the drum lid, and threaded in the Heavy Duty Dry Vac.

The EXAIR Chip Vac and Heavy Duty Dry Vac Systems.

It’s too soon to know for sure, but all signs point to a long, useful life. In fact, we’ve borne that theory out with in-house testing with numerous abrasive materials. We posted a video a while back, showing the effects of abrasive material conveyed through our Line Vac products: both the standard aluminum, and the hardened alloy Heavy Duty ones.  You can see the results for yourself, here.

If you’d like to get expert suggestions on your compressed air application, please give us a call.

Vac-u-Gun Improves Valve Cover Machining Operation

A machine shop called looking for a way to vacuum the scrap aluminum chips from their valve cover machining process. They were considering using a Line Vac Air Operated Conveyor to remove the chips, but preferred something hand held, so I recommended our Model # 6192, Vac-u-Gun Collection System.

Vac-u-Gun 6192

Model # 6192 Collection System includes Vac-u-Gun, reusable collection bag, extension wands and tools.

 

The Vac-u-Gun incorporates a nozzle insert where the orientation can be changed, allowing the unit to be used as a vacuum or a blow gun. Using the unit in vacuum mode would allow them to remove the chips and deposit them in the reusable collection bag (included with the system), rather than blow them in an undesired location in the shop. They could then change the direction of the insert and convert the unit to an air gun and blow off any residual cutting oils from the valve cover, reducing their overall process time. Also adding to their plant’s safety as the unit is OSHA compliant per Standard 1910.242(b) for 30 psi dead end pressure (cannot be dead ended) and allowable noise exposure per Standard 29 CFR 1910.95(a).

Vac-u-Gun orientation

Change from vacuum mode to blow mode in seconds!

 

This is another solution that EXAIR had on hand ready to ship same day to fit the customer’s needs.  If you have a similar application where operators are blowing debris into unwanted areas, please give us a call at 1-800-903-9247.
