IHP high-pressure stainless steel filters are designed for effective removal of solid particles, water, oil aerosols, hydrocarbons and other vapours from compressed air systems up to 420 bar. The compressed air quality required by ISO 8571-1 can be achieved with 5 different grades of filter elements (N5, N25, M, S and A). An external condensate drain (optional) must be used for efficient condensate drainage.
