    Product information "Water filter SYR DRUFI + DFR with pressure reducer"

    The SYR Drufi + DFR is a combination of fittings, specially developed for house entrance installation in accordance with DIN 1988, consisting of a semi-automatic backwash filter in accordance with DIN EN 13443-1 and a pressure reducer in accordance with DIN EN 1567. The Drufi + DFR combines the latest technology and the highest quality workmanship. Connected to a DN 50 drainage pipe, the integrated funnel directs the backwash water into the sewage system.

    Since the Drufi + DFR is equipped with a display ring for maintenance reminders according to DIN 1988, you always have the next backwash in view. In the case of the Drufi + DFR valve combination, the correct installation sequence according to DIN 1988 is observed. The Drufi flange program is used for installation in the pipeline. The flanges can be installed in vertical and horizontal lines. The built-in pressure reducer enables individual pressure setting and completes the excellent properties in the smallest of spaces. The Drufi + DFR consists of a mechanically acting, semi-automatic backwash filter. In addition, it is equipped with a flange seal, hexagon socket screws for flange mounting and an assembly key for the hexagon socket screws. The pressure reducer insert is set at the factory to 4 bar output pressure, whereby the external adjustment handle allows an individual pressure setting between 1.5 and 6 bar. An outlet pressure manometer is also part of the equipment of the Drufi + DFR.

    The filter cup is made of high quality plastic. The housing and the internal plastic parts are made of impact-resistant thermoplastic, the rubber parts are made of age-resistant elastomers. A low-lead, dezincification-resistant gunmetal alloy or stainless steel is used for all other functional parts. The ring seals used are made of asbestos-free fibers. All materials correspond to the recognized rules of technology. The plastic parts and elastomers that come into contact with water correspond to the KTW guideline of the Federal Environment Agency.
