Back At Ya!

This may not be big news as it happens almost every month.  EXAIR is continuing to grow our product line and this time it is something we have never done before.  This new EXAIR Engineered Solution doesn’t blow debris away, instead, it all comes back towards you.   Why would you want this you ask?  What does this new-fangled contraption look like?  Both of those questions will be answered below.

To answer the first question, why would you ever want debris to come back at you?  Well, this isn’t for just blowing any part or area out, this nozzle has been designed for a special purpose – to blow out pipes, tubes, extrusions, and even some blind holes or pockets.   This is ideal when working on a piping system that you may need to clean out and don’t want to push debris further into the system.   It is a quick and easy way to clean out chips from a saw cut operation for tubing or extrusion.  The nozzle could even be used to clean out cylinders or crank shaft openings on engine blocks.

So what is the name of this new nozzle and what does it look like?

What does it look like already!

What does it look like already!

 

The EXAIR Model 1006SS - Back Blow Nozzle

The EXAIR Model 1006SS – Back Blow Nozzle

This is it, the EXAIR model 1006SS Back Blow Nozzle.   The nozzle features a 1/4″ FNPT air inlet, a 3/4″ O.D. to fit into piping, extrusion, or holes, and two flats which allow for the use of a 5/8″ wrench to install the nozzle.   The nozzle is constructed of 316 Stainless Steel, utilizes  22 SCFM when operated at 80 psig, gives off 80 dBA and is designed for use with 7/8″ to 4″ I.D. pipe, tube, or holes.

The unit will also be available on our Safety Air Guns with Chip Shields to offer cleaning excellence and protection for the operators.  Like all of the stock EXAIR products, this is available with our 30 day guarantee.   So if you are not sure whether this nozzle will work on your application, give us a call, get one in, and put it through the paces.   If the Back Blow nozzle doesn’t meet your needs, simply let us know within 30 days from the date of purchase and we will take it back and provide you full credit.

If you want to discuss this nozzle or any other compressed air application, don’t hesitate to contact us.

Is it Blue or is it White?

Last night I’m browsing around my favorite social media sites, and I’m flooded with images of THE dress which is clearly white and gold (and clearly over exploited). Even though everyone says it is blue and black. How do you get blue and black confused with white and gold? Turns out that science is involved. People much smarter than me have pointed out that this is simple optical illusion (see the photo below). I don’t think the people taking the picture meant to trick everyone, but I wouldn’t be surprised, if they did.

Here is another example

Color Letter

The blocks containing “A” and “B” are the same color

This optical illusion had me very concerned. Two of our product lines use a white label or a blue label to differentiate between products.

Take for instance the High Powered Cold Gun and the Standard Cold Gun. The labels are the similar, but one is white and one is blue.

Cold Gun Lineup

Standard Cold Gun (Left) has a white label High Powered Cold Gun (right) blue label.

The Standard Cold Gun will generate 1,000 BTU/HR of cooling, and The High Powered Cold Gun can generate up to 2,000 BTU/HR. of cooling. I would hate for someone to confuse the two units.

Or look at the Reversible Drum Vac versus the High Lift Reversible Drum Vac?

IMG_4590

High Lift Reversible Drum Vac (left) Blue/Black Label. Reversible Drum Vac (right) Blue/White Label

The High Lift Reversible Drum Vac will lift liquids up to 15 feet vertically. The Reversible Drum Vac can pump 55 gallons in 90 seconds but is limited to 9′ vertical lift.

Could these products be confused, if someone takes a photo with lighting from the back? Sure, they could given the correct conditions, but the labels also say the “High Power” or “High Lift”. I think we can still tell the difference between the products. Man, that’s a relief. Here is a link to another photo of the dress. I was tricked, clearly it is black and blue.

Super Air Knife Removes Dust In Furniture Application

One of the biggest disruptions to the home furniture business in the latter half of the 20th century was the introduction of self-assembled units.  Consumers found more attractive prices for items they put together themselves, and manufacturers found a way to expand their markets.

This change, coupled with the advances in CNC machining, has led to a booming industry.  And, EXAIR Super Air Knives provide a solution within this industry that allows the manufacturer of component based furniture to package their items with better quality and at higher production rates.

Cutting and routing machine

The application involved cutting and routing components in the machine above.  The machining is precise, but the manufacturer found that the bottom of the pieces held an undesirable dust, and they needed a way to remove the dust before packaging.

Super Air Knife installed to blow off dust from the bottom of finished pieces

The solution was to install a Super Air Knife onto the machine, below the track rollers used to guide the ejected parts.  When the wood pieces travel over the Super Air Knife, the dust is blown away and they are completely ready for packaging.

Installing the Super Air Knife improved product quality and increased production throughput by removing a wasteful and needless process of hand treating each piece.

Trust EXAIR…We Provide Solutions

So, Brian Farno wrote a great piece on trust the other day: Why Trust EXAIR? I couldn’t agree more with his narrative of the ways in which trust permeates the culture here, is implied in every transaction (internal and external,) and is CRITICAL to our success…as individuals, and as a company.

I’ve had the pleasure of helping several people just recently by NOT recommending EXAIR products for their application. Now, that may seem counterintuitive, but they were fairly straightforward situations where we know our products just won’t work. For example:

*A conveyance application, unloading bulk material from tractor trailers. The caller needed to move hundreds of pounds per minute. Our Line Vacs have been known to move about 50 pounds per minute in certain circumstances.
*A static problem in an area with volatile vapors. Since our Static Eliminators use high voltage electricity, they can’t be used where ignition of such vapors could occur. Now, they’re shockless to touch, so they’re perfectly safe for use just about anywhere else, just so you know.
*An Air Knife application where their company management is insisting on the use of a blower. Our products are designed for use specifically, and solely, with compressed air. I actually gave them some STELLAR data on the actual costs of operating an engineered Super Air Knife versus a similarly rated blower/fan type device, so I have high hopes of moving this one to the “Win” column. And soon.

These are a few examples where we were able to apply, up front, our knowledge of our products’ capabilities…and limitations. For times when we might not know (yet,) we can find out, right here in the Efficiency Lab. Oftentimes, these are comprehensive tests of existing product, performed in direct comparison to EXAIR Intelligent Compressed Air Products. This is a service we’ll provide you for free, if you want to send in your current product(s) for testing. No cost; no obligation; no wait…we strive to test within a day of receiving your shipment.

Other times, someone wants to know if they can use a particular product in conjunction with another. One such caller was a current user of our Vac-u-Guns, but had a need for a fixed device. They asked about using a Model 6082 1-1/4” Aluminum Line Vac, mounted right where they wanted to suction up debris, depositing it directly into a Vac-u-Gun Filter Bag. I was able to set this up quite easily, and did a little informal test with some coffee grounds, paper clips, and a few coins…it performed superbly with all of these, so they placed the order. I then found out that they were blowing the debris off their part with an EXAIR Model 1100-9318 ¼” NPT Super Air Nozzle w/Stay Set Hose & Mag Base – so this made the application a total EXAIR solution!

A small Line Vac & Vac-u-Gun Filter Bag make for a quick, compact & convenient debris collection system.

We perform testing of this nature all the time, because we don’t want to tell you something if we don’t know it to be true. If you have an idea for, or questions about, an EXAIR product, give me a call.

Painting a clear picture

While we are waiting for the new addition to our family, we started making plans to move our first son into the second bedroom, his current playroom. We asked him what colors he wanted and without hesitation he rattled off….. “I want blue on the bottom, gray on the top and black in the middle” (chair rail). My wife and I cringed at the black chair rail and offered maybe a charcoal gray? or maybe just white? but these were NOT going to be options. The boy knows what he wants, “Dad, I am going to be a big brother now so I need a big boy room”.

We headed out to the local home improvement store to get some paint samples. Our son stood in amazement (confusion) as he gazed at the hundreds of different shades of blues and grays. He took one card after another until his hands were full and that’s about the time a store employee noticed his struggle and offered some assistance. The paint company provides the store with a touchscreen where you can design a room , complete with a chair rail and compare the different paint codes to see the various combinations together. This saved us a huge amount of time as our son was able to match up the colors he wanted, avoiding the potential for multiple trips back and forth to the store and eliminated wasting several gallons of paint.

This got me thinking…. Here at EXAIR, we receive calls from customers who are looking to replace their wasteful, loud and unsafe open pipe blowoffs with one our engineered air nozzles. All of EXAIR’s Air Nozzles and Jets meet the OSHA Standard 1910.42(b) for 30 psi dead end pressure (cannot be dead ended) and OSHA Standard 29 CFR 1910.95(a) for allowable noise exposure levels. Since we offer so many different nozzles, it can sometimes be confusing, but EXAIR has you taken care of with our Air Nozzles and Jets and High Force Air Nozzles Comparison Chart(s). The charts are sorted by compressed air consumption (when operating at 80 PSIG) and provides the nozzle Model #, material of construction, inlet size, air consumption, force and sound level, making it easy to match to your existing setup.

Why EXAIR Static Eliminators Are Better Than Passive Eliminators

The question comes up quite a bit around this time of year as to why an EXAIR Static Eliminator is better than using a passive static eliminator to eliminate the static.   To further the explanation of a passive static eliminator, it is typically called static tinsel and is found in a variety of forms. Passive eliminators are grounded wire or strap and must come in contact with the surface of a part in order to dissipate the static charge on only that surface.  This is generally found in the form of a bare wire or some type of conductive material (copper) that is strung across the path of your parts and must come into contact with the surface of your part.   A conductive material bar is shown below.

In order for this to eliminate the static on the part you must have the fabric actually contact the surface of your part.   There are several points that this can cause an issue, the first being this item drags across the surface of your product which can wear the conductive fibers down leading to the eliminators needing to be replaced.   Second, if you have a delicate, printed, or high gloss surface, you may not want anything to touch the surface and risk a blemish.   Third, these can collect dirt and debris which may become transferred to the product.   Last, complicated shapes cannot easily be met with the passive static eliminators, these are only going to work well with flat surfaces.

Active static eliminators, such as the Static Eliminators Product Line from EXAIR offers a variety of ways to actively eliminate the static on a surface without ever touching the product.   These are ideal for delicate surfaces, painted surfaces, complicated shapes, or even flat sheets.  The EXAIR line is available with or without compressed air assist which will not only utilize your compressed air efficiently while eliminating a static charge but also blow the debris or particulate off the part.   Units without compressed air operation can eliminate static charges up to 2″ away from a surface while a unit with compressed air will eliminate static up to 20′ away.

A Sample of EXAIR Static Eliminators

Because the units do not contact the parts there is no need for being concerned about contamination being transferred to the part, the eliminators will not wear down from dragging across a part or surface. EXAIR static eliminators are also low maintenance products.

To top it all off EXAIR will honor a 30 day guarantee to test the products in your facility.  As well as honor a 5 year built to last warranty on compressed air products and a 1 year warranty on any electrical component.

If you would like to eliminate your static problems, contact us.

Shocking Credit Cards Costs … In Manufacturing

Winter’s weather comes with a variety of problems. I hope that folks in the Northeast get a break from all this snow soon. In Cincinnati we have not had to deal with much precipitation this year, but it has been cold and gloomy for too long. Personally, I am ready for spring to come and to the see the flowers pop up. I’m also tired of the getting shocked every time I pet my dog. Also, his hair that generally falls everywhere is now stuck to the side of couch.

On a more serious note, the dry air of winter can have a significant impact on manufacturing processes. The same static that attracts dog hair to a couch will also attract dust on to a non-conductive substrate like plastic or glass. I was working with a customer this week who manufactures credit cards and gift cards with custom logos. They fell prey to the dry, statically charged air of winter which caused a quality issue during these winter months. To create the promotional cards, the company would first digitally print the logo on a PVC substrate. This substrate is then stacked to await lamination. As they pulled each sheet from the stack, a charge would build up on the surface which would attract any dust in the area. The dust needed to be removed before the last clear layer was applied or it showed up as ugly bumps on the card surface. This dust was nearly impossible to clean off and still maintain a good finish on the PVC substrate. They tried to wipe the material off with soft fabric, but the rubbing only increased the static while moving the dust around, not off the laminate.

Laminating Station with the 110036″ Super Ion Air Knife installed

Using an EXAIR Static Meter, part number 7905, the customer measured 19.5 kV/inch on the PVC sheets before lamination. Because of this charge the customer installed a 36″ Super Ion Air Knife, part number 111036, above the lamination station. The operator would pull a sheet from the stack and pass it under the Super Ion Air Knife. After passing under the Super Ion Air Knife the charge on the sheet read 1.3 kV/Inch, and the dust was removed by the air blowing from the Super Air Knife. This dust removal drastically reduced their scrap levels. In the 3 months of winter, it was accepted that they would loss approximately 15% of all the cards they created do to blemishes on the cards. After installing the Air Knives, they only scrapped 3% of the cards they created. This scrap rate was even better than there summer production. The air knives will now be used year round.  The Super Ion Air Knife reduced scrap by 80%! Also, operators no longer tried to clean the dust with cloth, which allowed them to increase their production.
