Halloween Blast from the Past: Milling Frozen Human Body

Published on by Tyler DanielLeave a comment

Every now and then, an application comes across our desks that’s a little out of the ordinary. With Halloween around the corner, it felt like the right time to revisit one of the strangest (and certainly most memorable) uses of EXAIR products we’ve ever come across.

Several years ago, a research group reached out with an unusual request. They were involved in a project studying human anatomy through a process that required milling a cadaver and then photographing each layer to build a precise, three-dimensional representation of the body. Each pass removed only about 300 microns of material, meaning that hundreds of layers were milled and documented throughout the process.

For the imaging to be accurate, each freshly milled surface had to be completely clean and evenly prepared before a photo was taken. Any debris or uneven surface finish could distort the final image, and repeating a cut or photo sequence was time-consuming. That’s where EXAIR came in.

To remove dust and debris left behind from the milling process, they incorporated a Stainless Steel Super Air Knife (Model 110012SS). The knife delivers a clean, uniform curtain of air across the surface, removing any residue without physically touching or damaging the material. Immediately following the blowoff, an Atomizing Spray Nozzle (Model EB1020SS) applied a fine mist of isopropyl alcohol across the surface to improve imaging contrast and clarity.

A Stay Set Hose (Model 9212) allowed the nozzle to be positioned precisely where it needed to be and to stay there through long hours of operation. This combination replaced a previous setup that relied on a liquid-only spray, which often left uneven coverage and required rework. With the EXAIR system in place, the team achieved consistent, repeatable preparation of each layer and saved significant time by eliminating variability in their process.

While it’s not every day we see our products used in anatomical research, this one stuck with us. It’s a great example of how compressed air solutions can improve consistency and control in highly specialized applications.

So, in the spirit of the season, we thought it was worth dusting off this story as a reminder that EXAIR products show up in all kinds of places. Whether you’re cooling, cleaning, coating, or even preparing something for a close-up, there’s usually an efficient way to do it with compressed air.

Have an unusual application of your own? We’d love to hear about it. Reach out to an Application Engineer today.

How Versatile Are EXAIR Compressed Air Products?

I wish I could quantify that, but we keep finding more and more applications for them:

Vortex Tubes are used all the time for cooling applications, down to MINUS 40 degrees (Fahrenheit OR Celsius…that’s the point where they’re both the same; no math required.) They also produce a HOT air flow, which we usually call “exhaust,” but some users actually use IT for heating, and call the COLD flow the “exhaust.”

The EXAIR Vortex Tube. Cold air from one end; hot air from the other. Fully adjustable. You can use either...it's fine with us; whatever you need.

Our E-Vac Vacuum Generators are popular for “pick-and-place” jobs…hook one up to a Vacuum Cup and you can move parts around all day long. One time, though, I helped a

customer who needed to “pick-and-place” individual small pieces of woven fabric, a lot like a coffee filter. Even our smallest E-Vac, supplied from a Pressure Regulator cranked all the way down, was too much…it would still pick up most of the stack. We found they could use a Model 120020 3/4″ Super Air Amplifier just fine…the Pressure Regulator was still cranked all the way down, and it picked them up one at a time.

No matter what you need to pick-and-place, we've got you covered.

Our Super Air Knives are perfect for blow off, drying, and cooling applications…whether you’re trying to rid your product of dirt/debris, water, or heat, a laminar curtain of adjustable air flow is a “textbook” solution. But I recently had the pleasure of helping a customer who needed to KEEP SOMETHING IN PLACE and called to ask about an Air Knife. They had small cups running single-file down a conveyor belt, with an overhead brush roller pushing down on them at one point so they could be treated on one side. Without something holding them in place, the tooling would simply push them off the side of the conveyor. It required frequent adjustment because they run different sized cups…and they almost always lost some cups when they switched to a different size, while “dialing in” the brush tension. By installing a Model 110036 36″ Aluminum Super Air Knife in place of the brush, they can hold any size cup in place with the downward air flow “curtain.” No more lost product when they don’t get the brush adjustment just right!

Continuous, even, fully adjustable curtain of air...EXAIR Super Air Knives come in lengths from 3 inches to 9 feet.

If you have a compressed air application you’d like to discuss, give me a call.  Perhaps we’ll find the next level of versatility!
