Air Filters FAQ Page

Question: What is “Air Treatment”?

Answer: All compressed air systems require dry, clean air and environmentally sound disposal of by products.  To ensure total system reliability, CompAir air treatment products include a broad range of dryers and coalescing filters to keep your downstream equipment free of moisture and contaminants. 

Question: Why do I need Filters?

Answer: Airborne contaminants from the atmosphere, such as dust, water vapor, and hydrocarbons enter the air system through the compressor intake. The compressor also contributes to the problem with wear particles, oil vapor and fine aerosols that leak past glands and seals from the oil sump into the compression chamber.  Such contaminants in the air system can affect the efficient operation of pneumatic devices and, over time, damage them.  Utilizing reliable filtration products ensure that the integrity of the compressed air system has not been compromised.

Question: Where do I use filters within the air system?

Answer: Filters can be placed after an air compressor’s (or stand alone) aftercooler, before a dryer (refrigerated, desiccant, membrane) as a prefilter, and after a dryer (refrigerated, desiccant, membrane) as an afterfilter.
