This high efficiency coalescing compressed air inline filter assembly by Chicago Pneumatic is designed to remove dust particles down to .01 micron and will remove oil aerosols and water vapor down to .01 mg/m3. A high efficiency coalescing filter is most commonly installed after a refrigerated air dryer to capture trace oil vapors from getting downstream. It will also act as a last resort filter, capture debris particles and moisture if the air dryer were to fail unexpectedly.
An automatic float drain valve is pre-installed on this filter assembly. This will drain moisture and oil aerosols automatically as contaminants accumulate. Maintenance staff no longer needs to drain the filter manually by unscrewing a pet cock style filter drain. Changing the elements is easy and can be done by simple unscrewing the bowl assembly, pulling out the old filter, and inserting a new filter element into its place.
This inline compressed air filter assembly will filter the air to a ISO 8573-1:2010 air purity class 2 rating.
Atmospheric air contains several impurities such as dust, various forms of hydrocarbons and water in the form of humidity. Once the air is compressed, their concentration is increased. As a result, these contaminants find their way to the compressed air circuit, causing wear and corrosion to the downstream equipment. Chicago Pneumatic air line filters remove these contaminants from the compressed air.
