Six Million Dollars Just Isn’t What It Used To Be…

Published on by Russ BowmanLeave a comment

…not that I’m turning down any recent offers, mind you, but I digress. You may recall that I opted out of my addiction…I mean, subscription…to cable television (almost two years ago) in favor of over-the-air broadcasting. As I wrote then, I was pleasantly surprised to find out there were a few dozen channels at my disposal. A couple of them are devoted to airing what they call “classic” TV shows.

One night, I was looking for something to watch, and stumbled across an episode of “The Six Million Dollar Man,” which was an honest-to-goodness STAPLE of my childhood TV viewing. And that’s saying something, because I watched a LOT of TV. As I eagerly watched this gem from the mid-1970’s, it became clear to me that, during its almost 40 years of storage, the recording media must have degraded with age, turning this once awesome show into a cheesy and predictable mishmash of physically improbable macho stunt heroics. It’s a shame they didn’t have a way of better preserving the film…curiously, though, the opening sequence wasn’t affected; it’s still cool as heck:

At EXAIR, you won’t find any stunt heroics…well, not outside our continuing series of Professor Penurious videos, anyway. You will, however, find that we’re very predictable. If you have questions about:

*Optimizing your compressed air system
*Efficient, quiet, and safe use of compressed air for blow off, cleaning, drying, cooling, etc.
*Atomized liquid spraying
*Static Elimination
*Air operated vacuum generators, up to 27”Hg
*Bulk material conveyance using compressed air
*Industrial vacuums
*Cold air as low as 50°F (46°C) for a variety of cooling applications

Then you can count on swift and accurate information from our Customer Service agents, and expert technical assistance from our Application Engineers. When you’re ready to order, you can expect same day shipment on just about anything in our catalog. Once you’ve got it, know that you can call us anytime with questions about installation, operation, “tips and tricks, “ etc. We want to make sure that you get the most out of our products.

As for the cheesiness….well, sometimes, it is what it is. ‘nuff said.

Testing A Freeze Out Valve

Published on by Brian FarnoLeave a comment

I recently had a customer contact me about an application where they were testing freeze out valves that go on the exterior of a locomotive.  The valve would be holding back about 45 psi of water in the pipe, and should open when the valve temperature reaches 35°F.  This would be used to keep any of the coolant / water lines from freezing during outdoor storage.

Mechanical Thermostat

The customer was using a chemical spray to freeze the mechanical thermostat and test that the valve opens.  Recently, an operator that was testing the valve used the wrong chemical and was hospitalized due to exposure so they decided it was time to change their testing method.

The customer purchased a Cold Gun Aircoolant System from our website, however, their compressed air temperature was 85-90°F and the Cold Gun is preset for a 50°F temperature drop at 100 PSIG inlet pressure. This means it wouldn’t quite reach the 35°F target reliably. Fortunately, EXAIR has a number of cooling products to cover an wide array of applications and our Adjustable Spot Cooler fit the application well since it can be adjusted to achieve much colder temperatures, up to a 100°F temperature drop from compressed air temperature.

EXAIR performed a test for the customer with the 25 SCFM generator installed and operated at 100 psig inlet pressure.   The valve was kept at a room temperature of 71°F and the compressed air inlet temperature was approximately 72°F.  The result was the valve would open in just under a minute.  This was even faster than the chemical test and it is adjustable to allow for the variance in the ambient temps. Success!

If you have any questions about how to use an Adjustable Spot Cooler in your application, please let me know.

Shock Cooling on Road Simulator

Published on by Lee EvansLeave a comment

Some time ago I had the opportunity to see a setup which cycles shock absorbers prior to their market release.  This particular design mimicked the contraction and expansion of the shock as if it were installed on a vehicle. Earlier this week I had a chance to work through a similar application on a more realistic setup.

Road Simulator

The photo above shows a complete chassis resting on wheel pans that simulate road conditions.  During testing, the shock absorbers increase in temperature because the entire system is stationary and there is no airflow to remove heat.  To make the testing more accurate and to cool the shock absorbers, Super Air Amplifiers were recommended to provide large volumes of air directed over the shocks and other chassis components.

This application is perfect for an Air Amplifier because Air Amplifiers are efficient at providing large volumes of air to a given area.  They can be used for cooling, light blow off, and even fumigation.
