Adapting To The Situation At Hand

Earlier this week I received a call from a customer who had an issue in his facility with the hand held blow guns the operators were using.   The units he had were simply too loud and he was trying to get below the 85 dBA threshold for hearing protection.  Not to mention they were using a large volume of compressed air.

I discussed the application with the customer only to discover they are blowing dry aluminum chips off a table and need a three foot extension so the operators can easily reach all extents.   The nozzles they had on their existing blow guns were essentially a cross drilled “safety nozzle”.  The customer was using the same model air gun throughout his facility at a total of 33 machining centers.   Each unit had a gun with a 3′ extension and a cross drilled nozzle like tip.

After discussing the amount of chips and what they were using I recommended he utilize a newer style adapter we have that would appear to work on his existing gun with the existing extension.  This means, rather than having to replace the entire air gun, extension pipe, and nozzle, he was able to purchase a simple adapter along with our model 1100 Super Air Nozzle and retrofit his entire facility.  This cut the budget needed by more than half of other solutions he was looking into from other companies.   Picture of the nozzle and adapter are below.

This was just another adapter for EXAIR but it was the right adapter for the customers existing product.  So if you have an existing blow off and you don’t want to replace the entire blow off device but you want to try and upgrade your system, contact us.

Questions for Selecting an Atomizing Spray Nozzle

AN1010SS

Did you know that the air and liquid caps of EXAIR Atomizing Nozzles are interchangeable? Maybe you do. But, do you know which parts are interchangeable? And, did you know that EXAIR Application Engineers have a quick reference chart for such information?

When it comes to liquid spraying, our customers will write to me for application assistance, technical specifications, and potential uses for Atomizing Nozzles. Sometimes the need is for new methods to apply liquid in an existing application.

Rubber Extrusison Painted with AN1010SS

This was the case in the photo above. The end user needed to apply a thin line of paint on a rubber extrusion. After the rubber is dried, it needs to be marked for easy identification during later handling. Using an AN1010SS, the end user has the option to apply atomized paint, and to automate the process so that paint is applied only as needed.

Atomizing Nozzles are also suitable for dust suppression (for example, at a waste transfer system), humidification (such as soften wood for processing), improving costly liquid usage, or spraying oil lubricant.
The best way to categorize an application for use with an Atomizing Nozzle is through a series of (5) questions.

  1. What is the desired spray pattern?
  2. What is the area size to be covered?
  3. How much liquid flow is required?
  4. Is there a pressurized liquid source?
  5. What is the viscosity of the fluid to be atomized?

Based on the answer to these questions the proper Atomizing Nozzle can be selected. If you need clarification on how these questions correlate to model number selection, a full staff of engineers are available for chat through EXAIR.com or over the phone/by email.

The Value Of Free Stuff…Sometimes, It’s Actually Worth The Price

I visited my doctor recently for my annual check-up. During the exam, he lamented that a lot of his patients didn’t take the importance of preventive care seriously enough. I joked that I’m actually one of those people, but since my health care insurance covers an annual check-up at no charge to me, I do it simply because I’m a sucker for free stuff. Again, I was JOKING…I firmly believe in the importance of preventive health care, and strongly encourage you, dear reader, to do the same and get annual check-ups.

Well, I was HALF joking, anyway…I AM a sucker for free stuff. In fact, my doctor and I went on to talk about how effective free stuff (like t-shirts) was at getting consumers to sign up for new credit cards, magazine subscriptions, etc. We had a good laugh, and I kept laughing…until I got home and looked in my t-shirt drawer…

Of course, these kinds of promotions can be great advertising – that’s obviously why they’re so popular, and at EXAIR, we’re keenly aware of that. Now, you can’t wear our free stuff for everyone to see, but, in the case of our current seasonal promotion, you can get something very useful for free:

EXAIR Cabinet Cooler Systems Control Humidity While Maintaining Internal Temperature

As the weather in the Northern Hemisphere changes over from winter to spring and temperatures start to climb, it is slowly becoming necessary for customers to utilize the Cabinet Cooler Systems to keep control panels cool.

One such situation involved a customer who was building a panel for his client in Malaysia. Malaysia is about 3 degrees north of the Equator, so it is what I would call a semi-tropical if not tropical environment. And such places are quite high in humidity levels. This customer had a client who was in the palm oil processing industry which is quite big in Malaysia. He needed a Cabinet Cooler System to generate about 1000 Btu/hr. of cooling power in a NEMA 12 type system. So I recommended he go with a 1700 Btu/hr. Cabinet Cooler System so he had plenty of capacity. I also recommended he go with 24 VDC thermostat control so he could easily pull the power out from within his panel and not have to run any new circuits.

As the customer duly noted, the fact that the Cabinet Cooler System purges the cabinet with clean, cool and dry compressed air allows for the humidity levels to hang down at a much lower level around 40 – 50% RH instead of up around 80 – 90%. This is attributed to the processing and drying of the compressed air at the production point before it is sent out to the facility and again at the point of use with the included, 5 micron, compressed air filter/separator that comes with each system.

Previously, the customer was using only the small, DC type fans to pull that hot, humid air through the panel which led to many corrosion issues and did not relieve the heat issue at all. With this new improvement, the end user no longer has to worry about such issues. Also, there is virtually no maintenance for this system which produces much longer up-times for the customer as there are no moving parts to wear out. Overall, it was a good recommendation in this case as the Cabinet Cooler System was handling multiple, previously negative issues. Now the pain has been taken away and the end user can move on to solving other, more pressing problems.

Video Blog: Changing Shims in Flat Super Air Nozzles

A brief video explaining just a few of the benefits to utilizing the EXAIR Flat Super Air Nozzles and how to change the shims which change the force and volume of flow out of the nozzle. Our shims and the adjustable air gap mean you can increase or decrease the volume of air flow and force without adjusting the inlet air pressure.

Can We Help Identify Your Existing EXAIR Product? – Yes.

From time to time we have customers call in and say “We have one of your products and need another. But we installed it so long ago that we no longer have the paperwork to know which model we bought.” That’s a great thing to hear in a way. Our products have outlasted their filing system, and not only that, but now we have potential to solve another problem for the same customer.

When this happens, we can sift through our files to find out which model was purchased, or if the original purchase was made through a third party, we can determine the model number in other ways. We can use the dimensions, material of construction, description over the phone, or a photo emailed to an Application Engineer such as the one below.

Cabinet Cooler

But, the needs of the application don’t end there. We may be able to pinpoint the model number of the device currently in use, but we also need to confirm that this model will be suitable for the new application. For the end user that sent in the photo above, this meant the completion of a Cabinet Cooler Sizing Guide for new heat load calculation.

What we determine in many cases is that the new application has specific needs which dictate the use of a product with different attributes (in this case a different Btu/Hr rating on a Cabinet Cooler). Whether it is because of heat load, ambient temperature concerns, required material, or any other variable, we are sure to provide the most suitable solution.

As spring gains momentum and warmer months are to come, it may be time to consider an EXAIR Cabinet Cooler solution for an overheating electrical panel in your facility. Contact an EXAIR Application Engineer for help calculating heat load and choosing the right system.
