COMFORT Exchange Filter WFD A25 including CBS-Lock Flange 1

The comfort-changeover filter WFD A25 is a valve combination developed specifically for house entrance installation according to DIN 1988, consisting of a cartridge filter according to DIN EN 13443 and a pressure reducer according to DIN EN 1567. Because it is sound-insulated (Group 1), the comfort-changeover filter WFD A25 is suitable for installation in residential buildings according to DIN 4109 (sound insulation in structural engineering). The comfort-changeover filter WFD A25 valve combination adheres to the correct installation sequence according to DIN 1988. The integrated design results in a particularly short overall length, making installation possible even in confined spaces. An connection set in sizes DN 20 - 32 is used for mounting into the pipeline. Thanks to the supplied CBS-Lock-Flange 1, the filter can be mounted in vertical and horizontal pipes. The built-in pressure reducer allows for economical pressure setting. The comfort-changeover filter WFD A25 consists of a cartridge filter with plastic filter elements. The pressure reducer insert is factory set to 4 bar outlet pressure, while the external adjustment knob allows individual pressure setting between 1.5 and 6 bar. In addition, the comfort-changeover filter WFD A25 features a display ring for filter maintenance reminders, a dual pressure gauge, and a connection flange with 1¼“ external thread (protected by thread protection caps) and 1“ internal thread for screw-free mounting.
