At EXAIR, we know compressed air, and we’ve been helping customers around the world get the most out of their compressed air systems since 1983. It was only logical that, about ten years ago, we got into using compressed air for liquid atomization. If you’re looking to spray a liquid in a fine mist with…
People often ask, “So what’s the big deal about nozzles?” They will also say, “I’m in an industry that is really tight with the purse strings these days due to the recession so presenting any new “expense” to the folks in accounting will be met with either extreme laughter or a stone cold NO. I’ve…
It’s not difficult to spray a liquid – oftentimes, you just need to pressurize it and force it out a small(ish) hole, or array of holes, in a nozzle-type device. If your application calls for small droplet size, a consistent & repeatable spray pattern, precise control of the flow rate, pattern size & shape, or…
First lets paint a picture, by starting with my first 400 Sq.Ft Bachelor pad in Holland Michigan. It was my first time after college living on my own and paying my own room and board! So I did what every fresh out of college 25-year-old male does, I scoured the internet for the cheapest possible…
My previous blog post was about how Vortex Tubes react when there is back pressure due to a restriction on either the hot or cold discharge of the Vortex Tube. In it I mentioned that there is a formula to calculate what the cooling capacity (Btu/Hr) will be if there is no way to avoid…
With Valentine’s Day coming up in the U.S. many of us will be buying chocolates for our significant other. My wife (somehow) doesn’t particularly care for chocolate, so I buy some for her anyway knowing that it will sit around until I eat it. I think most of us would agree that chocolate is even…
Over the last 3 months, I have been in contact with a customer, keeping track of an application that involved the EXAIR E-Vac. The customer had reached out to us looking for some advice on how to solve a process problem. The operation is a drawing/stamping process, and the when the part exits the machine there…
This past weekend we celebrated Labor Day. My family and I had the pleasure of going to a friend’s property and parking an RV to “glamp” for the weekend. The trip is only about 3-1/2 hours from our homes and when traveling in the RV it is a slow and steady wins the race kind…
The operation of a Vortex Tube is one of the more peculiar phenomena in fluidics, and a particularly unique method of producing cold air. Since they don’t perform “heat transfer” in the classical sense (see below), there’s no RATE of heat transfer…they’re generating cold air, at rated flow and temperature, instantly. Compressed air enters the…
I recently had a chat conversation with a customer who was looking to cool the tooling on his CNC router, mill and lathe in his small machine shop. As the day went on the tooling would begin to heat up, it would warp the bit, causing irregularities in the finished product. In some cases the…
