The best way to save compressed air is to simply turn it off when it’s not being used. This might seem pretty simple, but there may be processes in your facility where this couldn’t be achieved by just turning a valve. In applications where product is traveling along a conveyor, and must be dried, cooled, or blown off, there is likely some spacing in between the parts. It isn’t necessary to keep the blowoff running constantly if there’s periods of intermittent spacing. To help reduce the overall load on the air compressor, implementing a solution to shut the air off in between each part can have a dramatic impact. EXAIR’s Electronic Flow Control, or EFC, is designed to improve efficiency by reducing overall compressed air usage. It utilizes a photoelectric sensor that detects when the part is present. When it’s not, it triggers a solenoid valve to close and shut off the compressed air supply.
One way to use the Electronic Flow Control would be for Turning a Atomizing Spray nozzle on to coat your product. For example see the photo below where you could use the EFC to sense the pants coming down the line. Then turn the air supply on to spray a bleach solution to get the weathered look you are after. Once the pants pass the EFC will turn the nozzle off, replacing a manual operation awhile saving compressed air and your liquid solution!
Another use would be to tell when a hopper that is being filled by a Line Vac is empty or over filled. You can adjust the sensor and the control module to sense that the hopper is empty and it will turn the compressed air on to the Line Vac to then feed the hopper. Then set the timer module so it will run for the length of time it takes to fill the hopper. The other way would be to place the sensor at the top of the hopper and have it sense when the pile of media has reached the full level.
The EFC models available from stock can accommodate flows up to 350 SCFM. For applications requiring more compressed air, EFCs with dual solenoids are also available. If you have an application in one or more of your processes where intermittent compressed air use could help save you money, give us a call. We’d be happy to take a look at the application and help determine just how quickly the EFC could start paying YOU
The two words, doughnut, and donut are synonymous with each other. In research, the spelling donut is another Americanized word that didn’t catch on until the late 20th century. Either way, there are still multiple types of doughnuts. One of my favorites is shown below by one of the best donut manufacturers, NASCAR.
Maybe you are a little riskier and like some donuts that have a little less horsepower and a little more spice to them. Something like a ghost pepper doughnut that has a combination of spicy and sweet flavoring to satisfy your morning cravings for food. If so, you may be interested to know that an EXAIR Super Air Knife could have helped in the manufacturing process.
A regional bakery has opened up production and after months of determining their recipe and icing selection, they still needed some help on getting the glazing level correct on the finished doughnuts. The baked goodness would travel under a waterfall of glazing and several variables would lead to the amount of glazing that would build up/ remain on the doughnut. After testing these variables out the customer still wanted a better coating so they called EXAIR.
The solution, a 30″ 316 Stainless Steel Super Air Knife to mount over the conveyor and blow down the surplus glazing into the catch pan for recirculation. The variability in force from a gentle breeze up to a forceful, glaze stripping blast, was exactly what the baker ordered. This setup has been in practice for months now and nothing but positive results have been tasted, I mean seen.

I recently worked with a Chief Engineer on a large shipping boat who was having issues with water being brought in by the mooring cables. That salt water was getting into the maintenance room where the mooring cables were wound around a large spool. He wanted to remove the water from the cable before it went below deck so the extra water could just run off the deck back into the ocean.
After talking a bit we decided on a 4″ Super Air Wipe constructed of 303 stainless steel. This way the extra water would be removed and any debris the cable pulled in with it.
The Super Air Wipes provide a full 360° conical airflow that is used to blow-off, cool, clean and dry products. A Coanda profile is designed into the body of the unit to maximize entrainment of ambient air as well as give the precision angle for the air to exit from. This gives the air stream impacting the target zone a 30° angle to the surface in order to provide a substantial shear force for debris removal. This also ensures the large volume of ambient air entrained will all travel the correct direction and not become turbulent before impinging on the surface.
To meet all the tasks at hand, the Super Air Wipes are offered in two main materials of construction. Aluminum body with brass air fittings, connected with stainless steel hardware, shim and connecting hose for up to 4” (102mm). As well as 303 stainless steel body with stainless steel bolts, shim, the connecting hose for up to 4” (102mm) and fittings. The stainless-steel components give the units better corrosion resistance, higher temperature ratings, and more durability in harsh industrial environments.
EXAIR stocks the aluminum Super Air Wipes with inner diameters from 3/8” (10 mm) for wire and cables up to 11” (279mm) for large pipes and hoses. The aluminum models have a temperature rating up to 400oF (204oC). We also stock the stainless-steel models from ½” (13mm) to 4” (102mm) inner diameters, and they have a temperature range up to 800oF (427oC). If you require different diameters or materials, we can do that as well easily.
With the creation of the Super Air Wipe, uniform cleaning, cooling, and blowing around the outside of parts is a simple task. You don’t have to worry about a variety of nozzles to target the circumference or a fabricated blow-off device that will waste air and take much time out of your day. A simple purchase of the Super Air Wipe Kit will solve the problem and keep production going. If you need help in selecting the proper size or want to know what material we would recommend for your application, contact us.
While I was still in college, I worked in a meat processing plant as a Project Engineer in the maintenance department. During my time in the maintenance department I learned the importance of proper maintenance on machines. A meat processing plant is one of the most taxing environments on machines as they will have to survive in extreme cold temperatures to extreme hot temperatures; they are also put through deep sanitation wash downs multiple times a day sometimes for periods of over an hour. The plant really put into perspective the importance of preventative maintenance of machines. This includes utilities such as a boiler and of course your air compressor.
A primary focus to prevent an increased amount of wear on your compressor motor is to seal up compressed air leaks. Leaks can cause the compressor to cycle more often and/or refill receiver tanks on a more frequent basis, causing the motor to run more often. With the motor having to run more often to keep the air present, it will wear down faster. Using EXAIR’s Ultra Sonic Leak detector, leaks can be found in the pipes so that they can be sealed up.
