CHP carbon steel high pressure filters are designed for high efficient removal of solid particles, water, oil aerosols, hydrocarbons and other vapours from high pressure compressed air systems up to 420 bar. Required compressed air quality according to standard ISO 8571-1 can be achieved with 6 different grades of filter elements (B, P, R, M, S and A). Optional external condensate drain should be used for efficient condensate draining from filter housing.
