Heavy Duty Line Vacs: Made for Abrasive Materials and/or Higher Throughput

Published on by Jordan T ShouseLeave a comment

The Heavy Duty Line Vacs are made from a hardened alloy steel for abrasion resistance.  The generators inside these Line Vacs are more powerful than the standard models; so, that they can also convey heavier materials at higher conveyance rates.  They can reach rates as high as 40 lbs./min. (18.2Kg/min) of material.  With the hardened alloy construction, they are great for sand blasting applications, ceramic, glass, garnet, tumbling media and steel shot.  They are manufactured with inlet and outlet connections for ship-on hoses or threaded pipes.  EXAIR stocks the Heavy Duty Line Vacs in the range from ¾” (19mm) to 3” (76mm) for both hose and NPT connections.  These Line Vacs are our most powerful design with great wear resistance.

The table below gives a quick comparison of the EXAIR Light Duty Line Vac, Standard Line Vac & the Heavy Duty Line Vac models.  The test shows the 2″ size in each model conveying Rock Salt over two different horizontal distances.  As expected the Heavy Duty Line Vac conveys more material in less time!

Heavy Duty Line Vac Distance

The performance of the Heavy Duty Line Vac’s is nothing short of amazing!  With vacuum ratings between -144 to -20 inches of water column, it is more than likely there is a Heavy Duty Line Vac model that will suit your application.

Models range from 3/4″ OD to 3″ OD either in smooth bore or NPT threaded models for the ultimate in versatility.  The table below shows the different Heavy Duty Line Vac Models and their respective recommended kit, which includes a pressure regulator for fine tuning performance, filter separator to keep the compressed air supply clean and a mounting bracket.

Product Overview: Heavy Duty Line Vac for Conveying Abrasive & Heavy Materials

Published on by Leave a comment

The Heavy Duty Line Vac is EXAIR’s most powerful air conveyor.  While the appearance is similar to our other Line Vacs the Heavy Duty Line Vac it is constructed from a proprietary hardened alloy for greater wear resistance in highly abrasive applications, it is also designed to convey heavier product over greater distances!

Guess What Today Is?

Published on by Russ BowmanLeave a comment

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.

EXAIR Products Help Clean a Sandblasting Room

Published on by Dave WoernerLeave a comment

I’m sure there are any number of things that you could do incorrectly running a blasting room, but I became familiar with one failure mode this week: Clean Up.

I don’t know much about blasting rooms, but I know folks usually say this when it’s over –  clean up! That is a phrase I have heard once or twice in my life. We had a customer call in this week, who ran large pieces, one at a time through his sand blasting room, and needed to clean up after each operation. He had used electrically powered industrial vacuum cleaners in the past, but they did not hold up. He had a cyclonic separator in place, but enough dust and debris passed through the separator and into the impellers to create a maintenance nightmare. The problem had gotten so bad that before calling us he was using a broom and scoop method. The clean up was taking longer than the process, which made him unable to meet their production schedule, when the vacuum was down.

EXAIR’s solution the Heavy Duty Dry Vac (HDDV), model 6397. The HD Dry Vac fits onto a 55 gallon drum and uses compressed air to create a powerful vacuum, capable of moving over 50 pounds of ceramic tumbling media per minute.  The 6397 comes with a drum, drum dolly, 20 feet of compressed air hose, heavy duty accessory kit, and 10 feet of static eliminating vacuum hose, which allows the HDDV to clean easily in a 25 foot radius. Large enough to reach every corner of the customer’s 25′ X 25′ room.

I thought this would be great solution to the customer’s problem, but of course, the customer had one more wrinkle in his process.  His hopper for the blasting media was on the roof of his sand blasting room 12 feet in the air, and he needed to recycle the blasting media he collected. I can understand not wanting a new process to lift a 55 gallon drum up to the roof of his sand blasting booth after every part. Unfortunately, the HDDV, model 6397 would not be the best solution to vacuum and convey the blast media back into the hopper – but we do manufacture a solution, the EXAIR Line Vac.

The Heavy Duty Line Vac, model 150200, can easily transfer product up 12 feet in the air. After cleaning the floor of the facility, the customer setup a conveyance station with a 2″ Heavy Duty Line Vac to move the material to the hopper in the top of the roof. We were able to reuse the cyclonic separator he had from his electric vacuum to contain the material and release the air that is moved through the 2″ Heavy Duty Line Vac.

After using the EXAIR product, his cleaning time greatly decreased  Also, the Spill Recovery kit that comes with every 6397 Premium Heavy Duty Drum Vac greatly reduced the wear and tear on the employees backs and knees.  Finally, he effectively recycled his blast material with the 2″ Heavy Duty Line Vac air operated conveyor system.
