On our Website we have a comprehensive database of applications we have worked on with our products. These are pretty easy to find, Johns Blog will walk you through the process on how to access these applications. While John covered Compressed Air Use in the Construction Industry, I will be covering Compressed Air Use in Food and Beverage Industry.
EXAIR products are very commonly used in the food and beverage industry, from blowing water off cans before labeling, to conveying food products to hoppers for processing. See three examples from our application data base;

The image above shows a NEMA 4 Cabinet Cooler after years of use in a food production facility. The head electrician at the facility which uses this unit, contacted me regarding the possibility of installing thermostat controls on a pre-installed Cabinet Cooler systems. Apparently there are multiple EXAIR Cabinet Coolers in use around this facility, and as part of an improvement to compressed air efficiency, this facility wanted to explore automated regulation of the temperature in these enclosures (through thermostats). THis customer inquiry was about how to go about implementing such an upgrade.
It was refreshing for the end user to find that we have mechanical thermostat controls, solenoids, and even digital thermostatic solutions available from stock, making the upgrading process easy and pain-free. After some conversations over the phone and emailing part numbers along with our Cabinet Cooler Installation and Maintenance Guide, which outlines how to install the thermostat for our Cabinet Cooler systems, this customer had everything required to do exactly what they needed in their facility. (In this case, our model 9016 Solenoid Valve and Thermostat Kit met the voltage and compressed air flow requirements needed for the application.)
Providing efficient, controlled, and reliable solutions for industrial applications is all we do at EXAIR. If you have an application in need of a complete solution, or just an upgrade, contact an EXAIR Application Engineer. We’re happy to help.
Recently, I was working with a customer who specializes in post-harvest fruit processing. In this case, they were processing mangos from complete fruit down into cubes which are subsequently cleaned and packaged into plastic bags and then cardboard boxes for use in other food products.
When the customer contacted me, they were using a stainless steel pipe with holes drilled into it to de-water the fruit chunks after being sprayed to clean the individual pieces. They were using stainless steel pipe as they had a requirement for stainless steel construction due to being food grade facility. The problem with the pipe was that the airflow didn’t provide an even blowing force across the full, 30 inch width of the vibratory conveyor. The pipe solution also used quite a lot of compressed air. Unfortunately the customer could not measure what it was, but they gave me the number and size of the holes drilled into it. From that information, we could determine that they were using about 150 SCFM of compressed air at this one location.
And so, with the ineffectiveness of the pipe as well as the high air consumption, the customer went looking for something better. That’s when they found EXAIR Stainless Steel Super Air Knives on our web site. After some quick discussion to sort out the width of the conveyor and to establish what the need was, we settled on model 110030SS (30” 303 Stainless Steel Super Air Knife) to be mounted across the width of the conveyor (see photo above).
With the Super Air Knife installed, the customer was able to achieve the effectiveness he needed for the de-watering and at an airflow rate that was 42% less compressed air use than what he had before. Some of the other benefits that they were able to achieve without even being conscious of it were the enhanced safety of the OSHA compliant Super Air Knife and the sound level was cut dramatically as well.
EXAIR’s Super Air Knives are used many times in processing and packaging applications to provide a non-contact method for de-watering, blowing off dust, moving product off to one side, drying, ejecting and many more applications like these.

Our customer has a process where they de-cap eggs which are used in a variety of processes ranging from large scale bakery uses to medical uses for developing vaccines. The problem is they are left with a reasonable amount of egg shell waste that needs to be cleaned up after each cycle in the de-capping process. The previous method relied simply on friction and gravity to get the egg shell to go into the direction the customer wanted.
The problem with this method is that reliability was quite low. Egg shell would remain inside the egg, inside the tooling and pretty much everywhere around the de-capping process. The customer wanted to clean things up in the process a bit and increase the reliability that the shells go where they want them to which is a waste container about 5 meters away from the de-capper. The rate of shell flow was about 20 kilos per hour.
The customer made a search on the Internet for Air Vacuum conveyors and found EXAIR Corporation. After a short discussion to find out the specifics concerning rate of flow, distance, density of the product and available air pressure, we were able to make a suitable recommendation.
We ended up recommending EXAIR Model 6963 (1-1/2” Stainless Steel Line Vac kit). Having the full kit available allows the customer to install the Line Vac using included bracket for mounting as well as the air filter/separator and compressed air regulator with gauge to allow for accurate tuning of the air pressure to get just the right amount of suction from the Line Vac unit.
The customer purchased the recommended kit and installed on their machine. They have claimed the reliability has gotten to the point where the problem has nearly gone away. They still had some issues with the blades used, which they intend to sort out as a next step in their process of continuous improvement.
