Glass Filled PEEK Super Air Knife w/ Brass Hardware & PTFE Shim? No Problem!

That’s right folks, we’ve gone and done it again.  When a customer calls for custom product because their environment calls for it or due to dimensional requirements, EXAIR has the ability and flexibility to meet those needs!

This time around it was a customer with specific material requirements due to their environment. I had a customer contact me recently that was using an aluminum Super Air Knife near a high voltage operation and was getting ground interference due to the aluminum air knife.  They asked if it was possible to make them a custom knife out of PEEK plastic.  After some light discussions about the form of the knife and what other materials are safe for their environment we settled on a 30% glass filled PEEK plastic for the knife, brass bolts and pipe plugs, with a PTFE shim installed.   The form factor of the knife would follow the same shape as our PVDF Super Air Knives that are available from stock.   The customer could not use PVDF due to high temperature and potential off-gassing in the process.

The results are shown below.

Super Sized Is Not A Problem At EXAIR

For many years we as Americans wanted to biggie size, super size, or mega size anything and everything we could.   For myself that mainly meant the fries and drink I used to get at any local fast food joint.   Now that I have hit my mid-30s and all of that has started to catch up to me, I don’t always want the large fry or any fries at all, instead I might try a new salad and trying to eat healthy.  Here at EXAIR, we don’t always associate bigger with better but we do always fill the need when we don’t have something off the shelf.

However, there are still occasions where going super size is necessary and this week, we did just that.   We had a customer ask if we can go bigger on our Super Air Wipes.   We simply asked how big they needed to go and what the reasoning is for it.  Turns out, the reasoning for the larger Super Air Wipe was a newly designed automated cell in a pipe manufacturing facility.   The stock 11″ was too small to fit the 11″ max. diameter piece through to blow off debris so they requested a 12″ Super Air Wipe.   To top off the customization, they were also in need of BP threaded air inlets.

Catalog 30 Stock Air Wipe Sizes

Within a matter of weeks our customer has gone from a product they didn’t know was possible, to shipping out to their site.  This is a one off, custom machined, Super Air Wipe that has a 12″ Throat Diameter.   The only parts on this that are from our standard stock are the bolts, stickers, and the connecting / hinge plates(The clam shell design requires these.).

If you have an application where you don’t think we have exactly what you need or maybe you need to go bigger, or smaller, than what we show in the catalog don’t move on and try to find something else.   Give an Application Engineer a call and we will see how we can tailor our products to your exact needs.

Custom, Flanged Air Amplifier Solves a Fume Evacuation Problem

We blog about this topic quite a bit, and almost every section of our catalog has a page set aside just for special / custom product configurations that have been created by request from many of our customers.

This is the latest and greatest special that I have seen roll through the production area here at EXAIR.   This is a special 4″ 303 Stainless Steel Adjustable Air Amplifier with a 4″ Tri-Clamp flange on the discharge side and a 6″ Tri-Clamp flange on the suction side of the amplifier.

 

This had been an ongoing project with the customer that started with them testing a stock Adjustable Air Amplifier in the application to ensure that the performance would meet their needs.  The application was to boost a low flowing fume exhaust that was causing slow downs in their production line.  Fans and other traditional methods would require maintenance and would wear out.  The stock Adj. Air Amplifiers exceeded their performance needs but did not easily mount into their duct work because they used all standard size tri-clamp fitting in the ducting, so the next step was to see if we could manufacture a Special Adjustable Air Amplifier just for their needs.  The dimensions of the existing Adjustable Air Amplifier came close enough we were able to easily create a Flanged Adjsutable Air Amplifier that would clamp straight into their existing duct work, exceed their performance expectations, help their process, and be ready to ship within a very reasonable lead time.

Like we have said before, if a stock, cataloged, product doesn’t fit your application exactly, contact us and let us find a way to customize and fit the need.

Need A Flange? We Can Do That!

I recently had a customer call in that was trying to boost an exhaust on a hot operation that he had in his facility.   We discussed what kind of fumes he was trying to evacuate and it appeared at face value that a High Temp Air Amplifier would be the perfect solution for his application.

A Model 121021 1-1/4" High Temp Air Amplifier directs hot air to a rotational mold cavity for uniform wall thickness of the plastic part.

A Model 121021 1-1/4″ High Temp Air Amplifier directs hot air to a rotational mold cavity for uniform wall thickness of the plastic part.

Then the words that strike fear into some manufacturers came out.  The customer asks, do you have any way to put a 4 bolt flange onto the unit so I can mount it straight into my piping system?   My response, “All I need are the dimensions of the flange you need and we will see what is possible.”  After a few further questions and verification, we had a drawing  with dimensions of a Flanged High Temp Air Amplifier.  We sent the drawing to the customer for approval, and once approved, we began to manufacture the custom product and provided it to the customer.  This unit will allow the customer to easily boost the exhaust on his operation and will bolt straight into his piping so there are no worries on his end about exhaust gas escaping.  His 500°F air temperature of the gases are of no concern to this special as it carries with it the high temperature rating of 700°F.  The pictures below show the Special – Flanged High Temp Air Amplifier.

Here you can see the low pressure side (intake) of the Special High Temp Air Amplifier.

The O.D. of the flanges was 6″ with 4 – 3/4″: bolt holes. The Bolt holes were not required to align with the opposing side.

If you think there is no way we can find a product that will fit your compressed air application, or adapt a product to fit then give us a call, you might just be surprised at what we can offer in a quick turn around.

Shared Details Equal Better Solutions

Fortunately for us, and our customers, we manufacture custom parts to meet their application if our cataloged products do not meet their requirements. Just look at these blogs. Customers often come to us to know if our products can be used in a corrosive environment, or if they are suitable within a high temperature, or within a small envelope.  Shortly after I started working in the Application Engineering department, I have found that the answers to these questions are generally “Yes, but why?”

Our marketing department does a great job of displaying our capabilities.  Just look at the special pages: Air Knives, Line Vacs, Air Amplifiers, or Cabinet Coolers. We can make a great variety of products and materials, but we always will ask the next question. Why?

Some customers are surprised at how emphatic we can be about knowing why you need a special part or process. We are only asking to best serve you. For instance, I had a customer come to me today after seeing our Special Air Knife page and seeing our flat Super Air Knife that is only 11/16″ thick.  This is a great product for its application, but when compared to our stock Super Air Knife, it is more expensive and carries and cannot be shipped until 2-3 weeks after it is ordered since we would build it from scratch.  Customers first look at the Super Air Knife and see that the overall height of the product is 1.44″, which is too large to fit in their machine.  When they see that the Super Air Knife is too big they assume they need something special.  This is generally, when I get a call like this.

“I need your Flat Super Air Knife. What is the part number and price?”

Flat Super

“We don’t have a standing part number for that unit. It was a special part that we created for a specific customer. Why do you need that model?” I reply.

“It is thinner than the Super Air Knife.” – customer

“Have you looked at the Full Flow Air Knife?” – my reply

“No, What is that?” – customer

This is where the reasoning behind the request is so important. Purchasing one piece of a custom made thin Super Air Knife pictured above is significantly more expensive than the production run and in stock Full Flow Air Knife.  The Special thin Super Air Knife is 0.688″ thick. The Full Flow Super Air Knife is 1.03″ thick. And in this case case, the Full Flow Air Knife worked for this customer.  This is just one example of finding out why a customer needs a special product is so important.  If the machine envelope is 1.25″ the Full Flow Air Knife will fit just fine. If the machining envelope is 0.75″, a Special thin Super Air Knife will be the solution. When we share the details together, it is easier to produce the best solution for our customers.
