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.

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.

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.

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.
