The overall beer market in 2019 was $116 billion, with nearly $30 billion of that made up by the smaller breweries in the craft beer sector. Whether a large or small operation, one piece of equipment that drives many of the core functions in a brewery is an air compressor. An air compressor delivers pressurized air, which has been generated by a motor or engine, to be used for a wide range of applications throughout the brewery.

Compressed air is viewed as the “fourth utility” (after water, gas and electric). A brewery air compressor is no exception, as this equipment is behind several of the functions that the brewery requires to operate.


Air Compressors in Breweries

A brewery air compressor fulfills numerous functions throughout the facility, including:

  • Moving beer: If beer is being conditioned in a secondary tank, compressed air can be used to make this transfer. To be bottled or canned, beer must be moved from the brewing or conditioning tank to the bottling or canning machine. Compressed air is the most efficient way to carry this out, ensuring that lines remain clean and dry between movement processes.
  • Aeration: During fermentation, oxygen is required for the fermenting yeasts in the beer wort to do their job of converting sugars to alcohol. Beer air compressors are used to deliver this oxygen in a controlled, efficient and clean manner.
  • Clarification: The clarification process is used to remove undesired “haze” from a beer, for a clearer appearance and a cleaner taste. Air compressors are frequently used in this process to drive a centrifuge, which can remove unwanted solid material from the beer.
  • Equipment cleaning: From kettles to tanks and kegs to bottles — not to mention the lines that move beer and ingredients from one stage of brewing to the next — it is critically important that all equipment in the brewing operation be clean and free of contaminants. If they aren’t, the beer will not taste as intended, and entire batches may need to be discarded. Compressed air is used to clean brewery equipment so that nothing makes it into the beer that shouldn’t be there.


Choosing the Right Brewery Air Compressor

Rotary screw air compressors are the compressor of choice for breweries, offering numerous benefits that are ideal for all the brewery applications in which they are used. These benefits include:

  • Versatility: Rotary screw compressors provide the high-pressure air needed for every operation in a brewery — bottling, capping, cleaning and more.
  • Extended use: Rotary screw compressors are suitable for continuous duty, remaining in operation throughout brewing hours and, for brewpub restaurants, operating hours.
  • Consistent flow: Rotary screw air compressors are designed to deliver the maximum flow 24 hours a day, seven days a week. Piston compressors, due to not having an oil cooler, require shutdown time for cooling. They would burn up if they ran 24/7.
  • Efficiency: Rotary screw compressors operate at the highest level of efficiency, providing the best ROI for your compressor investment.
  • Low-noise: Especially for breweries with a brewpub or restaurant attached, as well as operations with a smaller facility footprint, quieter air compressors are more desirable. Rotary screw compressors are the quietest compressor available.
