Mini Chip Vac Reduces Rework, Increases Safety

I recently worked with a customer who was starting to experience material defects due to contamination during their machining process. There were also safety concerns, as the operators were cutting themselves by hand cleaning the shavings out of the bores and wiping the surface of the machines clean. They were considering using another standard electric workshop vacuum but had been reluctant due to their history of motors burning out, so they called EXAIR looking for a suitable compressed air operated vacuum.

I recommended using our Model # 6193-5, Mini Chip Vac System. The Mini Chip Vac uses compressed air to create a powerful vacuum, picking up dry or wet chips and delivering them to a 5 gallon drum (also available in 30, 55 and 110 gallon sizes). There are no moving parts, motors or electricity required to operate the unit, eliminating the customer’s concern for potential shock.

By using the Mini Chip Vac, the customer was able to remove the contaminants from the process, increase safety by eliminating the potential for injury, reduced the amount of defects and reduced downtime. The 5 gallon mini Chip Vac is also capable of being placed in tight spots and does not take up too much space. They were so satisfied with the results, they even made their own stand.

Identifying Reversible Drum Vac or High Lift Reversible Drum Vac

This summer we rolled out a new High Lift Reversible Drum Vac. Today, I received a phone call trying to figure out what Drum Vac the customer had. This led me to write a blog, “How can you tell the difference between a Reversible Drum Vac and a High Lift Reversible Drum Vac?”

The first identifier on the High Lift Reversible Drum Vac is the blue and black label attached to the muffler (pictured below), the label on our standard Reversible Drum Vac is silver and blue.

High Lift Reversible Drum Vac Label

As time goes on the label may disappear from these rugged units after years of use. Our engineering team has had some forethought in this area, and we created a physical difference in the units that will not be removed, edited, or worn away. To confirm the identity of your Reversible Drum Vac, unscrew the body of the Reversible Drum Vac from muffler.

The High Lift Reversible Drum Vac will have a groove machined into the plug of the body. The Standard Reversible Drum Vac will be a smooth finish.

The High Lift Reversible Drum Vac doubles the lift of a Standard Reversible Drum Vac, which makes it great for any below grade liquid cleaning operations. The additional vacuum strength of the High Lift Reversible Drum Vac can be used to move viscous materials. Sludge, vegetable oil, and heavy motor oil can now be lifted from a coolant sump or trap at heights up to 15′ vertically. On top of this extra lifting capacity it features the same benefits as the Reversible Drum Vac. With no moving parts to wear out and no electricity required, it can operate safely and effectively for years.

Heavy Duty HEPA Vac Reduces Dust When Vacuuming

hepafam_collection

EXAIR Heavy Duty HEPA Vacuum Systems

When selecting the proper EXAIR vacuum system for an application, several details are considered by our Application Engineers.  For example:

Does the vacuum need to vacuum liquids or solids?

If the need is to vacuum solid material, what is the approximate size of the material pieces?

How quickly does the material need to be vacuumed?

What is the compressed air supply available?

Is dust a major concern?

The last question becomes more relevant with finer material, especially dust or small dirt particles.  Many applications have a need for dust control and need a vacuum system capable of maintaining low dust levels.

The EXAIR Heavy Duty HEPA Vac was designed for this exact purpose.  With a HEPA filter that is tested in strict accordance to IEST-RP-CC-007 standards to provide a minimum of 99.97% filtration at the 0.3 micron level, the Heavy Duty HEPA Vac can provide an effective and highly efficient vacuuming method using only compressed air.

Fine Powder Hopper 2

Hopper used for fine powder collection

For example, in the fine dust collection hopper shown above, the hopper undergoes regular cleaning and maintenance which includes a thorough cleaning to remove any fine dust remaining in the hopper. This powder has a tendency to permeate the filtration used in most vacuums, and electrically powered units have continuously failed.

The Heavy Duty HEPA Vac is a perfect fit for this application need as it can provide adequate filtration, and it has no moving parts to wear out.

If you have a dusty or difficult vacuum application in need of a sustainable vacuum system, contact an EXAIR Application Engineer to discuss the Heavy Duty HEPA Vac.

A Dull Knife Is A Dangerous Knife

Anyone who’s ever cooked, hunted, crafted, fished, whittled, opened a well sealed package, or sharpened a stick for roasting marshmallows knows what I mean. A dull knife requires more force to cut your material, which means that you’re using less of your muscle strength to control the blade. If you’re not sure of where the blade is going, that’s a heck of a thing to leave to chance, especially if you’re holding what you’re cutting in your other hand.

Even if (I might even say “especially if”) you don’t use a knife for cutting every day, the conventional wisdom dictates that you should keep its blade sharp. Not only is this imperative for safety reasons (see above,) but you’re going to make a MUCH higher quality cut as well.

Sharp blades result from high quality material that is professionally crafted, and expertly maintained. The cheaper the material, the easier the blade will dull. High carbon stainless steel blades cost a little more, but they’re also easier to sharpen, and they stay sharp longer. A decent stamping machine can turn out hundreds of blades an hour, but forging a single piece of metal results in a level of hardness that is much more conducive to maintaining a sharp edge. Speaking of maintaining a sharp edge, that’s going to be left up to the user. A lot of hardware stores provide sharpening services, but it’s not all that hard. Expert results can be obtained by following what the experts do, and the Boy Scouts of America have taken pride in doing stuff like this for over a hundred years now. Full disclosure: I’ve been a Scout Leader for over nine years now, so I may be biased, but I am unapologetically so. I use these tips, and my pocketknife is VERY sharp.

High quality material, professionally crafted and expertly maintained, is, of course, a successful recipe for a great many products other than knife blades. EXAIR applies these principles to every single item in our 168-page catalog of Intelligent Compressed Air® Products. Here are just a couple of examples:

*The Super Air Knife (no relation to the cutting tools discussed above) is available in a range of materials: aircraft grade aluminum, types 303 or 316 stainless steel, or PVDF. They’re engineered for maximum efficiency, minimum noise level, and manufactured to exacting quality standards.

Capture
*The Heavy Duty HEPA Vac System turns your open top drum into a powerful, high capacity, dust free, industrial vacuum. It’s made of a hardened alloy for superior abrasion resistance, and, with no moving parts, it’s virtually maintenance free.

Exair-heavy-duty-HEPA-vacuum

I could go on, but these are the two products, and the benefits they provide, that I’ve actually discussed with potential users just today. If you’d like to know more about how EXAIR products can keep the use of your compressed air sharp, effective, and safe, give me a call.

Vac-u-Gun Makes the Job Easier and Safer

I worked with a customer this week who was wanting to use one of our small Light Duty Line Vacs to remove plastic chips from their small machining operation. The Light Duty Line Vac  is a lesser version of our more powerful Line Vac models and provides an alternative solution for conveying smaller volumes of material over a short distance.

Light Duty Line Vac

Our family of Light Duty Line Vacs are built for use with 3/4″ to 6″ hose or pipe.

The customer is currently using an ordinary blow gun to blow out the chips onto the floor which was creating an unsafe work area. Another concern was the decrease in production, as the operator would need to stop machining, find a broom, sweep up the chips and dump them in a receptacle. To eliminate this, they were thinking that the operator could manually use the Light Duty Line Vac to vacuum the chips and convey them to the collection receptacle which was only about 5 feet away.

The Light Duty Line Vac would have worked well in the application, but since the process of vacuuming the chips would remain a manual operation, I mentioned our Model 6292 Vac-u-Gun Transfer System. The Vac-u-Gun is a hand held product, with a trigger valve built in. It is a more ergonomic and efficient solution than the Light Duty Line Vac. The Vac-u-Gun can be used as a vacuum gun, blow gun or transfer tool providing the customer with a single tool for a variety of different jobs. Utilizing only 13 SCFM @ 80 PSIG, it creates a vacuum of -29.5” H2O and produces a force of 9 ounces. By changing the orientation of the nozzle insert, the unit can be easily changed from a vacuum gun to an efficient blow gun.

Offered in 3 different systems to cover several applications:

Vac-u-Gun Systems
By choosing the Vac-u-Gun rather than the Light Duty Line Vac, the customer was able to keep the manual operation, eliminate the unsafe working conditions, perform the job with less compressed air and improve their overall production. I was happy to assist them with the information to make the best decision.

At EXAIR, we have many different intelligent compressed air products that may fit your application. For help selecting the best option, please don’t hesitate to contact us. We are always willing to help!

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.

Need A Lift? Use the New High Lift Reversible Drum Vac

At EXAIR we continue to develop new products to meet our customer’s needs. For example, check out Brian Farno’s blog titled “Once Again EXAIR Is First To Tackle The Impossible”, introducing our new single piece construction, Long Super Air Knives (up to 108”- In Stock!).

I would like to introduce another new product, our High Lift Reversible Drum Vac. Consuming only 43 SCFM @ 80 PSIG, this system will produce a lift of 180” H2O or 15 feet – filling a 55 gallon drum in less than 85 seconds! With 3 available sizes, 30, 55 or 110 gallon, this system is designed to quickly attach to any closed head drum. The High Lift Reversible Drum Vac can also move thicker liquids than the standard duty product.

HLRDV

You can easily convert this system to a pump, providing 30 GPM (water), with the simple turn of a knob – quickly emptying the drum.

Requiring no electricity and with a built in pressure/vacuum relief, these units are safe to operate. Considering these units have no moving parts, they are virtually maintenance free.
