What Does Air Treatment Mean?

It means CLEAN AIR!

When speaking of air compressors, compressed air treatment is a process that dehumidifies and cleans air before entering the compressor. Most commonly, this process involves air filters and an air dryer. An effective compressed air treatment system lowers the “dew point” of the air and takes out particles that may negatively harm the air compressor.

Protecting your investment is a smart decision with your compressed air system. Not only does compressed air treatment allow your system to run more efficiently, but it also prolongs the life of the system by reducing rust and corrosion that can be caused by wet, dirty air. Because the air being used by the air compressor is clean, it can run faster and doesn’t contain particles that can corrode the compressor over time. Also, air that has undergone compressed air treatment is dry, meaning it does not promote the growth of rust like wet or humid air does.

What Types of Air Treatment Are Out There?

Explore the list below of different air treatment solutions. In-Line Filters: primarily to remove rust, scale, dirt, and other solid particles. Particulate filters are very versatile and can be used with either lubricated or non-lubricated compressors. Often used to filter before and after the air enters & exits the compressor. Dryer: Removes moisture from compressed air. Available in different types based on your application and needs. Air/Oil separator: A device in the compressor that separates oil from the air/oil mixture compressed in the air-end. Condensate Drains: Collect and discharge liquids from after-coolers, separators, receivers, dryers, filters, and drip legs.
