The EXAIR Chip Trapper filters solid debris from your coolant that can not only clog the supply lines to the tooling, but also provide a LOT of surface area for the growth of bacteria. This can really foul the air in a machine shop, and sometimes, it can mess with your skin, causing a rash or infection. Honestly, this isn’t a HUGE problem…I’ve fielded a handful of calls about it over the years, though, so when I got the call from a machinist last week who wanted to talk about a possible solution for a skin problem, I immediately thought of the Chip Trapper.
Well, immediately after I thought about this old commercial (I’ve written before about how I watched way too much television growing up. Don’t judge.)
Turns out, though, his problem wasn’t bacterial – it was an allergic reaction he was having with a specific additive in the coolant used on a particular machine tool. He mentioned that it was a mist coolant application, so I immediately thought of the Cold Gun Aircoolant System.
Of, course, right after I thought about this commercial (seriously; stop judging.)
To my knowledge, it’s the first time we’ve ever applied a Cold Gun to solve a skin problem – we’re almost always looking at them to avoid the mess of coolant spray, or to increase tool life in situations where traditional machine tool coolant is impractical (or impossible) to use.
If you’d like to find out how EXAIR products can save you from:
I recently received an inquiry from a customer to test their current air guns through our Efficiency Lab service. According to the operators, the handheld blow gun they were purchasing from a commercial retailer was too loud and complaints were rolling in. They were also hoping to save some compressed air in the process as they were performing an energy audit at the same time.
The gun they sent in looked fairly similar to our Precision Safety Air Gun but it did not have an engineered nozzle on the tip of it. Instead, it was simply a cross cut hole in a piece of material. The air inlet to the gun was a 1/4″ NPT just like our Precision Safety Air Gun, the extension on the gun was slightly longer, the only significant variance I saw was the tip.
To try and get as much information as possible I measured the O.D. and I.D. of the extension, the hole size was approximately .140″. I measured the extension on our Precision Safety Air Gun just to see what is different, it came in at the same size. So, I flow tested the competitive blow gun with their tip on it and came up with air consumption of 12.69 SCFM, noise level of 92 dBA at 3′ away, and a blowing force of 11.5 oz at 80 psig. I then measured the same attributes of EXAIR’s model 1410SS-CS Precision Safety Air Gun at 80 psig inlet pressure. The model 1410SS-CS measured 8.3 SCFM, gave 8.1 ozs of working force, and only produced a 75 dBA sound level from 3′ away.
The sound level reduction was a total of 17 dBA which is below the OSHA standard for allowable noise level exposure, as well as reduced their air consumption by 4.39 SCFM. That is almost a 35% reduction in their compressed air usage per gun replaced. After seeing these levels of reduction the customer had more than enough information to provide management with in order to replace the blow guns not just for noise level reduction but also because it will reduce air use and save money. A clear supportive role in their energy audit.
