Luck of the Irish and Compressed Air Give Us Beer

With the Luck of the Irish and a little help from air compressors we will all be enjoying a pint of our favorite beer on St. Patrick’s Day.

St. Patrick’s Day, started on March 17, 1631 when the Church established a Feast Day honoring St. Patrick, the Patron Saint of Ireland.

Modern St. Patrick’s Day celebrations, at least in New Zealand, are less to do with the historical figure of the saint and more to do with corned beef and cabbage and green beer. And lucky for us, air compressors assist in bringing us both.

Compressed air is essential in the beer making process. It is used in almost every stage of the brewing process including:

Bottling/Canning – to get beer in the bottles and cans we buy - compressed air is used to move beer from the conditioning tank to the bottle. It is also used for keeping the lines clean. Class 0 oil-free air will make sure the lines and tanks do not get polluted in the process.

CO2 Recovery – one option is to recover the CO2 that is created during the fermentation process and either use it to carbonate your products or by storing it and later selling it.

Cleaning air – Oil-free compressed air is used for cleaning bottles and packaging prior to the filling. It is important the air is clean, if the air is contaminated it can alter the flavor, odor and foam as well as being a health hazard.

Fermentation – during the fermentation process, Compressed air supplies oxygen to bacteria. This converts carbon hydrates to alcohol using micro-organisms. It is extremely important to deliver the exact amount of compressed air and maintaining the correct oxygen level to determine the quality of yeast.

Packaging/labeling – Compressed air is used to control the valves and actuators in automated lines for packaging, labelling and more.

Wastewater treatment – Water used during the brewing process must be treated before it can be returned to the water cycle to minimize its impact on the environment. The air needed for this treatment must be oil-free of the water would be contaminated again.

So, we hope on St. Patrick’s Day, that you raised your favorite pint with your friends honoring St. Patrick, remember compressed air played in your day. Sláinte!

Your company purchased an air dryer for your compressor, now where should you install it? One of the most common things we see in the industry are air dryers being stored on top of the compressors. Seems like a wasted space not being used on top of the compressor, right? Wrong.


When using air compressors, there are many variables that are integral to the quality and effectiveness of your compressed air. When dryer air is necessary, being able to constantly and accurately monitor dew points can be a critical factor to your operation.


Compressed air plays an integral role in breweries both large and small around the world. From start to finish, all details in the brewing process are managed in fine detail and having the right air compressor is no exception.
