What is a compressed air dryer?

Compressed air dryers are filtering systems that rid your compressed air of moisture created during the compression process. It makes sure that your compressed air is high-quality and free of harmful moisture that could damage your equipment or have a negative effect during use.

Compressed air filters, on the other hand, filter the air from other impurities like dust and gases.

How your compressed air dryer works depends on the type of air dryer you have. Each uses a different technique to the same result: providing clean and dry compressed air for you to work with.

The most common compressed air dryers and their basic working principles:

  • Refrigerated air dryers are the most common type of compressed air dryer. They work by cooling the air down until the moisture condenses, extracting it from the air. They are also known as refrigerant air dryers.
  • Adsorption air dryers are usually used as a second stage dryer. They use hydrophilic substances to extract moisture from the air. Well-known sub-groups are desiccant and deliquescent air dryers.
  • Membrane air dryers contain a hydrophilic membrane for the air to pass over moisture builds up on the membrane and migrates along the length of the membrane before being expelled.
