BF filters are designed for protection of the downstream compressed air system and equipment against defects and other failures. Due to their robust welded carbon steel construction, are used for installation in heavy industrial applications with high air flows.They ensure high efficient removal of solid particles, water, oil aerosols, hydrocarbons, odour and vapours from compressed air systems up to 16 bar. Required compressed air quality according to standard ISO 8573 can be achieved with 6 different grades of filter elements (B, P, R, M, S and A). Optional external condensate drains should be used for efficient condensate draining from filter housing. Fluid group 1 on request.
