It is used to filter particles washed into the drinking water and helps protect the house water installation from malfunctions, deposits, and damage caused by foreign matter.\u003c\/p\u003e \u003cp\u003eThe DN20 version with 3\/4-inch connection is suitable for use in house installations as well as for compact installation situations. Thanks to the integrated pressure reducer, the DUO DFR 2314 is particularly useful where, in addition to filtration, pressure regulation of the drinking water installation is also required.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe SYR DUO DFR 2314 is designed as a manual backwash filter with pressure reducer, pressure gauge, and integrated 360° rotatable connection flange. The pressure reducer is preset at the factory to 4 bar and can be individually adjusted in the range from 1.5 to 6 bar.\u003c\/p\u003e \u003cp\u003eThe filter element works with stainless steel mesh. The lower passage width is 90 µm, the upper passage width is 125 µm. The filter bowl is made of impact-resistant plastic; plastic parts and elastomers that come into contact with water meet KTW requirements.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe manual backwash function facilitates regular filter maintenance and requires no special tools.
