Don’t Waste Money On Your Waste Removal

Lately, we have been receiving calls from customers that are looking for a wet/dry vac that they are accustomed to seeing in the form of an electrical vacuum for their home work shop.  They call us wanting a general clean up vacuum for their shop.  The items they are looking to clean up are coolant, dust and chips.  Our solution for this is to run two vacuums, and most people are asking why can’t it do both.  The answer – cost.

Generally, people seeking EXAIR’s pneumatic vacuums already see the value in the durability of a vacuum with no moving parts to maintain or replace when comparing to electric vacuums. It is the simplest of dollar savings,  the longer the product lasts and is maintenance free, the more money you will save from the absence of repair parts or new vacuums. And electric vacuums are notorious for burning up motors and not lasting within tough industrial environments. You can read about additional features/benefits within EXAIR’s pneumatic vacuum line here and here, but I will talk about our products specifications in detail.

EXAIR has two categories of vacuum, wet vacs and dry vacs.  The original wet vac for vacuuming coolant, swarf, or oil is the Reversible Drum Vac (RDV), used to easily empty and fill coolant sumps quickly. The Chip Trapper features a filtration system which removes chips and debris that is within the coolant, keeping the coolant clean, extending the coolant life and minimizing surfaces for bacteria to grow.  The Reversible Drum Vac and the Chip Trapper Systems use 19 SCFM of compressed air at 80 PSIG of and can fill a drum with 55 gallons of water in 90 seconds. These workhorse vacuums will last many years and withstand the rugged treatment found in hardworking manufacturing facilities.

Drum Vac

In the other category of  our industrial vacuums are the “dry” vacuums.  This term “dry” is a little ambiguous, because the vacuums will be able to move some liquid.  For instance, the liquid coating a chip or spills on the shop floor can easily be picked up with the dry vacuums.  We have a number of dry vacuums available:  The Chip Vac is a continuous duty vacuum used for general cleanup around machinery. The Chip Vac drum lid assembly can be used from drum to drum to aid in separating and recycling materials. Our Heavy Duty Dry Vac is best for applications vacuuming heavy materials, abrasive medias or longer distance (20′). And the Heavy Duty HEPA Vac is designed to provide protection from airborne particulate and is suited for dusty environments.

To compare EXAIR products with other pneumatic vacuums, let’s look at the Chip Vac (40 SCFM at 80 PSIG) and the RDV above (19 SCFM at 80 PSIG). Combining the two vacuums you would require (59 SCFM at 80 PSIG. If you search long enough, you could find a pneumatic vacuum that is advertised as wet/dry, but this ability comes at a cost.  The most obvious cost is the upfront purchase price, which is consistently much higher than the combined cost of the (2) EXAIR units.  Also the units range in air use from 68 SCFM to 110 SCFM.  That is up to 86% more air required!

Let’s assume that you did run both constantly.  The wet/dry vac will cost you $0.14 extra an hour to run, assuming that your compressed air cost is $0.25 per 1,000 SCF.  That is really an unfair comparison to our products though, because we could have (2) vacuums operating at different locations in the plant accomplishing twice as much work.  Even still the (2) EXAIR units will save $810 per year with 250 working days in a year and 24 working hours in a day.

$810 per year may not sound like to much to you.  What if we change the scenario? How much air can you save? Let’s say you run a large wet/dry vacuum, which consumes 110 SCFM, everyday for 8 hours over 250 working days. The wet/dry vacuum will use 52,800 SCF per day or 13,200,000 SCF per year.  This compress air will cost you $3,300 just to compress that air. By comparison, the Chip Vac will only cost you $1,200 per year to run in compressed air.  Using the Chip Vac instead of the wet/dry vac, will save you $2,100 per year. in compressed air operating costs.

EXAIR Products Help Clean a Sandblasting Room

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.

The Case Is Made for Heavy Duty HEPA Vac

Exair-heavy-duty-HEPA-vacuum

I had an interesting discussion with an overseas customer recently. They had come to us looking for a commercial offer for our Vac-U-Gun product. Then were asking about our Deep Hole Vac-U-Gun product. It was one of those scenarios where the customer appears to know what they want and have their models all picked out.

We have developed a natural curiosity for how folks are using our products around here so I asked him about his application. He seemed to know what he wanted, I just wanted to know how he was going to use the product in case I needed it for a future conversation to relate product usefulness to someone else. It turns out that his intention was to use the Vac-U-Gun to vacuum up dried coffee creamer in their production environment.

You may be thinking that we do promote the Vac-U-Gun for such cleaning applications. The issue here was that this was the only thing the Vac-U-Gun was going to be used for and they had quite a bit of volume to suck up on any given day. Upwards of 20 lbs. of the stuff.  That’s a lot of creamer!

After we had our discussion, I made a suggestion that the customer seriously consider using another of our products that would be better suited to picking up dusty and powdery product. That would be our Heavy Duty HEPA Vac. While the Vac-U-Gun would have certainly picked up the product, the filtering media of the bag would have quickly become clogged and they would have had to continuously clean it throughout each daily use. This isn’t a scenario that I would want our customers to be saddled with when trying to purchase a solution from our company. So, I began talking about the features of the Heavy Duty HEPA Vac.

The most valuable feature that I felt would be helpful for this customer was the fact that we utilize a thick, pre-filter material to catch a large portion of any dust that might come through. The Heavy Duty HEPA Vac is able to vacuum up a whole 55 gallon drum worth of dusty material before cleaning of the pre-filter becomes necessary. And even then, all that is necessary is to knock it against the inside wall of a garbage can to get the bulk of the dust to drop off. Then it is right back to the vacuum system and ready for more use.

With this in mind, I knew that the Heavy Duty HEPA Vac system would be more than adequate to help this customer make his cleaning operations much more effective and easier to perform. The customer is still weighing his options at this point but is now seriously considering a tool that would be a much better option than their current method of a broom and dust pan.

If you have a particularly dusty clean-up application, you should give the Heavy Duty HEPA Vac a try. You will not be disappointed.

What Makes Compressed Air Vacuums Better

I was recently given an article that was titled, “Shop Vac Flaws Grind Use to a Halt”.  This article was written by a gentleman whose original electric vacuum had declined in performance which led to acquiring a new model electric vacuum. The conclusion he draws in the end is, an old worn out decreased performance electric vacuum is better than a new electric vacuum. EXAIR knows the only comparison you can make with electric vacuums is to compare one to another – when comparing an electric vacuum to a pneumatic powered vacuum, there is no comparison. A pneumatic vacuum with no moving parts to wear out, break or decline in performance is a better vacuum.

In the end the author goes back to using his old vacuum because it didn’t require as much maintenance as his new unit.  This is where the beauty of a compressed air powered vacuum comes into play.  If he would have originally purchased a unit such as our Chip Vac or our Heavy Duty Dry Vac, which are both available in 5, 30, 55, and 110 gallon sizes, he wouldn’t have experienced any of these problems.  Our units have no internal moving parts, no bearings to grease or wear out, no motors to oil or clean. The author’s electric vacuum was missing a screw, EXAIR’s level of quality inspection eliminates the possibility for a product to arrive without a fastener.

Our units will not lose suction over time because the impeller is weak,  this is because there is no impeller to even worry about.  The only maintenance item you will encounter on our unit is the 0.1 micron filter bag which is washable and reusable.  This means you could have one vacuum that will last decades and will not need to be repaired every year.

The EXAIR Chip Vac has the equivalent suction force of around a 5 HP electric vacuum while the Heavy Duty Dry Vac will be equivalent to around a 7 HP vacuum.   No matter which unit you would choose to try they are both backed by EXAIR’s 30 day guarantee, along with our 5 year built to last warranty.  I don’t know of any electric vacuum cleaner made for shop use with a warranty or guarantee that can come close to that.  So why buy something that was designed by monkeys, choose something that was designed and made by experts in their field who stand behind what they make.
