The Drufi+ plus DFF is a fitting combination specially developed for domestic inlet 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 Drufi+ DFF is suitable for installation in residential buildings according to DIN 4109 (sound insulation in building construction). The Drufi+ DFF fitting combination complies with the correct installation sequence according to DIN 1988. The Drufi+ DFF combines modern technology with modern design and high-quality workmanship. The Drufi flange program is used for mounting in the pipeline. The flanges can be installed in vertical and horizontal lines. The integrated pressure reducer allows for a reduced pressure setting.
The Drufi+ DFF consists of a cartridge filter with plastic filter elements. It is also equipped with a flange gasket, hexagon socket screws for flange mounting, a mounting wrench for the hexagon socket screws, and a filter bowl wrench for filter maintenance. The pressure reducer insert is factory set to 4 bar outlet pressure, with the external adjustment knob allowing individual pressure adjustment between 1.5 and 6 bar.
