COMFORT Backwash Filter RF A25 incl. CBS-Lock Flange 1

The comfort backwash filter RF A25 is a compact fitting specially developed for house entrance installation according to DIN 1988 and conforming to DIN EN 13443-1. Because it is sound-insulated (Group 1), it is suitable for installation in residential buildings according to DIN 4109 (sound insulation in building construction). Connected to a DN 50 drain pipe, the funnel directs the backwash water into the sewage system. The compact fitting comfort backwash filter RF A25 adheres to the correct installation sequence according to DIN 1988. The integrated design results in a particularly short overall length, allowing installation even in confined spaces. A connection set in sizes DN 20 - 32 is used for mounting into the pipeline. The included CBS-Lock-Flange 1 allows the filter to be mounted in vertical and horizontal pipes. The comfort backwash filter RF A25 consists of a mechanically acting, semi-automatic backwash filter, a double pressure gauge, and a connection flange with a 1¼" external thread (protected by thread protection caps) and a 1" internal thread for screwless mounting.
