HP BF filters are designed to protect any downstream equipment in a high-pressure compressed air system. Thanks to their robust welded carbon steel construction, they are used in heavy industrial applications with high air flow rates. They provide effective removal of solid particles, water, oil aerosols, hydrocarbons, odours and vapours from compressed air systems up to 25 or 50 bar. The compressed air quality required by ISO 8571-1 can be achieved with 6 different levels of filter elements (B, P, R, M, S and A). External condensate drains (optional) must be used for efficient condensate drainage from the filter housing. Fluid group 1 on request.
