Compressed air is not free! But when used correctly, it’s a tool that, in most cases, is the most effective option! 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 are 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.
EXAIR EFC
One way to use the Electronic Flow Control would be to turn an Atomizing Spray nozzle on to coat your product. For example see the photo below where you can 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 while 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.
I was recently contacted by a manufacturer of specialty food products that was looking to increase productivity on one of their packaging lines. In order to do so, they needed a longer Super Air Knife.
Model 110012SS-316 Super Air Knife
They manufacture a variety of different products, but this application involved small snack-sized blocks of cheese. They’re placed into individual plastic containers, and before they seal the packaging any residual particles must be blown off, or affect the seal. Any residual particles of cheese around the container would allow air to come into contact with the product and affect shelf-life.
In the current setup, the customer is using EXAIR’s Model 110012SS-316 a 12” 316 grade Stainless Steel Super Air Knife, and the Model 9060 Universal Mounting System. They wanted to add in an additional two rows of cheese to help increase throughput. To do so, he needed an overall width of 18”. We do have an 18” available from stock, but rather than having a spare 12” model lying around, he wanted to try and utilize what he had without having to purchase an entirely new knife.
Model 9060 Universal Mounting System
Fortunately, EXAIR’s Super Air Knives can be coupled together to create a wide variety of different lengths. From stock, the Super Air Knife is available from 3”-108”. With the help of a Super Air Knife Coupling kit, we can achieve much longer lengths. In this case, although we did have an 18” knife available, we could also couple the existing 110012SS-316 (12”) with our Model 110006SS-316 (6”). This option was a bit cheaper than going with a new knife, and still allowed them to utilize the 12” that they already had.
Coupling Kit for Aluminum Super Air Knives
While this isn’t the typical application we’d recommend a coupling kit, it was an option that allowed the customer to save a bit of money but still get the same effect that they’d achieve with the 18”, single piece Air Knife. We also manufacture a wide variety of custom knives per customer specifications. If you’ve got an odd application that you don’t think is best served by a stock offering, give us a call. An Application Engineer will be happy to take a look at your application and help recommend the most suitable product.
