Air Wipes, How They Work Video

A customer from the Czech Republic contacted me earlier today and was interested in our Super Air Wipe product. They produce vacuum hoses and need to blow water from one of their extruded profiles. They asked me if they could get come catalog data and a video showing one of the Super Air Wipes in action.

The catalog data was no problem. All of that information is contained on our web site under our PDF Library as Catalog product sections. It is easy enough to go there and download whatever you might need whether it be the catalog, our Blowoff Guide, Installation & Maintenance Guides or our price list. They are all arranged there in tidy PDF files that can be downloaded at a moment’s notice. Very convenient.

The part I was wondering about was whether we had a video showing our Super Air Wipe in action. I knew we haven’t produced an official EXAIR video on them yet. But I wondered whether we had an informal video showing one in action. Turns out my colleague Dave Woerner put together a concise video showing available types and sizes of the Air Wipe and showed how a wetted pipe was blown completely dry by one of the Super Air Wipes.  Awesome!  I enjoy answering customer inquiries about our products, but I really love it when we are able to leverage each other’s efforts to produce such good and informational videos about the products to make our replies back to our customers that much more engaging.

So, if you need to know how to operate our Ultrasonic Leak Detector, change a shim in a Super Air Knife, or perhaps you need to know how to clean and rebuild your Reversible Drum Vac to get it up and running again, don’t hesitate to search the EXAIR Blog for these highly useful videos. They help us every day. They can help you too.

Searching the phrase “video blog” and the name of the product will be the first step toward finding the helpful video.

Air Knives – What Are They Good For?

It is rare that a week goes by without a unique application of an EXAIR product…

This week I was speaking with a DJ who wished to use an air knife to create a blast of air that would add emphasis to the musical experience had by his fans. He wanted a small burst of air that would last less than a second, but would add an additional element to an already very complicated setup. My initial reaction was that no DJ I have ever seen would possibly be able to supply an air compressor big enough to feed the air knives, but over the course of our conversation, I found out that the DJ travels with 2 semi trucks of equipment, so he had some space.

An Aluminum EXAIR Super Air Knife

Another topic that came up in our conversation was how air knives were generally used. I have been asked this in a number of ways: What are they designed to do? Where do they work best? or What are they for?

I never have a succinct answer… The air knives create a flat laminar sheet of air in various sizes from 3″ up to 108″. This laminar sheet of air can be used to move, open, float, or separate. It can be used to clean, dry, or cool. I try to categorize these applications as best I can when speaking to customers, but then you talk to a DJ, and he wants an air knife to make a crowd cheer. I never thought that would be an application for an air knife. Knowing this, how do you convey all the air knife can do in a succinct answer?

Well, I can’t, so please be patient when you ask me the same question and I run through applications from cleaning surfaces to entertaining DJ crowds.

Here is a rundown of air knife applications. In case you don’t believe me.

Move: Air Knives are used around to world to move product from a conveyor to another location.

Open: Air Knives uniform air flow is perfect for opening bags or other packaging on a packaging machine.

Float: If you need to bridge a gap between two conveyors, the air knife has done this for products from pizza dough to sheets of veneer.

Clean: Blowing products off after removing them from a CNC machine is an easy air knife application.

Dry: One of my tastiest applications was to use an air knife to blow water from a potato chip after washing, but before frying.

Cool: Extrusion, molds, and baked goods have all been cooled with an air knife.

Just because it isn’t on this list though, doesn’t mean it is not possible.  This is why we will stand behind our stock product with our 30 day guarantee.   So if you want to try an EXAIR Air Knife in your application, give us a call.

Cold Gun Removes Heat From A Peening Operation

Last week I worked with a customer who is peening the edge of an aluminum sheet. Toward the end of the run, and approximately every six inches, they were starting to see irregularities due to warping of the sheet and other heat-related damage. They were allocating a lot of valuable machining time to try and rework the sheet but in many cases the product had to be scrapped anyway. They even installed a misting system and while it worked to provide the cooling, there was now an additional step of wiping the sheet dry, so they called EXAIR for a solution.

I recommended using our Model # 5215 Cold Gun System for the application. Incorporating a Vortex Tube, the Cold Gun produces a cold air stream at 50°F below compressed air supply temperature and provides 1,000 Btu/hr. of cooling capacity. Fitted with a magnetic base and flexible hose the unit can be mounted virtually anywhere on the machine and the cold airflow can be easily directed to provide cooling to the critical area. The system also includes a filter separator for the supply line to remove any water or contaminants, ensuring virtually maintenance free operation.

The #5215 produces 1000 Btu/Hour of cooling and was enough capacity to prevent the heat related problems and warping using only cold air. By removing the heat and any liquid from the process the customer eliminated the extra steps they had to put in place without any cooling and the extra steps they had in place with liquid cooling. Success!

Video Blog: Measuring Surface Temperature and Air Temperature Requires Different Tools

IR Temperature Guns are a great tool for measuring surface temperatures, but not the best solution for providing the air temperature data EXAIR needs to size a Cabinet Cooler system for your electronic cabinets. This brief video illustrates the differences between using an IR temp gun and a regular thermometer when gathering temperatures to determine Cabinet Cooler system specifications.

Make sure to print out the Cabinet Cooler Sizing Guide before you get started so you can easily fill in all the needed data.

EXAIR’s Free Efficiency Lab – How Much Money Can It Save You?

In many of my blogs, I talk about specific products benefits or applications, but this week I want to talk about a service that EXAIR provides to our customers: Efficiency Labs. The Efficiency Lab is comprehensive study of your current blow off. You can ship your current blow off to our facility. We can test it with our calibrated equipment and record your current product characteristics. Our most popular efficiency lab is testing home made blow offs. These are blow offs made from copper tubes, thumb guns with nozzles removed, or drilled pipe. These blow offs can get the job done, but they are noisy, wasteful and dangerous. Every compressed air expert knows that these blow offs need replaced, but sometimes it may difficult to decide which nozzle to use. By sending us your current blow off product(s) we can measure the force, flow, and noise of the blow off and provide a comprehensive report. This report, in most cases, compares your current setup against what EXAIR we would recommend to save compressed air, lower noise levels and maintain performance.

 In addition to providing a blow off suggestion, EXAIR’s efficiency lab can identify your energy cost for these blow offs. The standard industrial cost for compressed air is $0.25 per 1000 standard cubic feet. At first glance that might not seem like much, but it can add up. This week I did an efficiency lab for a customer that used 1/4 ID copper tube as their home made blow off.

open copper tube

This 1/4″ Open Blow off uses 30.8 SCFM of compressed air.

This small open tube ran continuously for 10 hours per day five days a week. To run this tube, cost a company $1,175 per year. The tube would flow 30.8 SCFM of compressed air when fed with 80 PSIG. By installing an EXAIR Super Air Nozzle,  part number 1100, the company could save 16.8 SCFM of compressed air and $650 per year. Once again $650 may not seem like much, but they used up to (40) of these open blow offs depending on what part they ran. Replacing all (40) of these blow offs saves $26,000 per year at a capital investment of $2,880 for (40) 1100-9212, Super Air Nozzle with 12 inch stay set hose. That would be a simple ROI of 72 days.  That ROI is only taking into account compressed air cost. Additionally, the 1100 Super Air Nozzle will reduce noise by 28 dBA and it complies with OSHA Standard CFR 1910.242(b) for dead end pressure.

We have found that our customers all have unique setups which greatly vary the values of their particular blow off. Even if customers have the same 1/4″ tube, the way they implement it can greatly affect its performance. Variations in inlet pressure, length, diameter tolerance and even what they used to cut it to length can have an impact on how much air it will consume. If you want to know for certain how much air and money you can save, use our free Efficiency Lab service.

EXAIR can save a lot for you!
