CHP carbon steel high-pressure filters are designed for effective removal of solid particles, water, oil aerosols, hydrocarbons and other vapours from high-pressure compressed air systems up to 420 bar. The compressed air quality required by ISO 8571-1 can be achieved with 6 different grades of filter elements (B, P, R, M, S and A). An external condensate drain (optional) must be used for efficient removal of condensate from the filtration.
