The post How to remove contaminants from your compressed air system? first appeared on ELGi.]]> The atmospheric air comprises of moisture, particle contaminants, microorganisms and gases. When this air gets compressed, the concentration of such particles these increases by 6-10 times. However, when this atmospheric air gets compressed by a compressor, other contaminants like oil & traces of metal get added during the compression process. This is why, it is important to remove these contaminants from the compressed air before it is used for any application.

These contaminants can be categorized into:
1. Particles
2. Water (Liquid, vapor and aerosol)
3. Oil (Liquid, vapor and aerosol)
4. Microorganisms
5. Other gases

According to the International Standard, ISO 8573-1:2010, compressed air contaminants like particles, water and oil are segregated as per purity classes. In this standard, microorganisms and other gases are not included. As a result, the air purity is indicated as [P,W,O] and is ordered as per the amount of particles, water and oil.
