Compressed Air Uses In Industry

Published on by exaircorpLeave a comment

From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.

Compressed air is used in virtually every industry!

 

Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.

Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.

Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

EXAIR has been providing engineered solutions since 1983.

EXAIR’s Cabinet Cooler Systems Cool Electrical Enclosures

Published on by Brian FarnoLeave a comment

One of the main focuses for Cabinet Cooler Systems is to cool electrical enclosures that are overheating due to inadequate cooling, failing air conditioners, or heat exchangers that are not performing due to high ambient conditions.  Another focus is the fact that the Cabinet Cooler Systems don’t require refrigerant based coolants, or fans that can move dirty ambient air into the cabinet. This is the portion I would like to focus on today.

If there are vents on the enclosure then these are sometimes covered with a filter media that is an easily forgotten maintenance item –  sometimes they are even removed.  This is an issue as it starts to allow the contaminants from the surrounding area to begin to enter the inside of an enclosure.  In case you have never seen a circuit board that is covered in oil mist and metal chips, it is terrifying to see a maintenance person that is trying to troubleshoot the machine for failures.  Not only does this present a fire hazard but it also presents the internals of the panel with a strong probability of failure.

Another item I have personally seen fail in the field are small fans mounted within enclosure vents to help circulate air through the enclosure.  This is a great idea if the ambient environment is climate controlled and has no dirt or debris in the air.   Even in a facility that is climate controlled there is still potential for airborne debris, dust, and contaminants to enter the cabinets. These are merely accelerated into the cabinet by the fan and distributed throughout the entire enclosure instead of just coming in and covering the area just inside of the vent.

The solution to all the problems above which can easily save thousands of dollars worth of damaged circuit boards or drives is an EXAIR Cabinet Cooler System.  The Cabinet Coolers will all provide a slight positive air flow within the enclosure and will help to keep those external ambient conditions out of the cabinet and away from valuable electronics.  Even with our thermostatically controlled systems (which turn on and off as needed to maintain internal temperature AND save air) we offer a Non-Hazardous Purge option which will permit a 1 SCFM flow of air through the Cabinet Cooler to always keep a slight positive pressure within the enclosure. When the cabinet needs to be cooled, it will open the solenoid valve and provide the full rate of cooling from the Cabinet Cooler System.  The Non-Hazardous Purge function is available for all three NEMA types of Cabinet Cooler Systems, 12, 4, and 4X.
