SYR DUO DFR manual backflow filter with pressure reducer and manometer
Connection dimension DN 20 ( 3/4" )
Application
The Duo DFR is the entry-level filter in the SYR filter program. It is used as a filter fitting for drinking water installations according to DIN 1988. Installation is carried out with the help of the fully rotatable integrated connection flange. The Duo DFR works in all installation positions. Thanks to its very compact design, it can also be used to protect individual devices (dishwashers, drinking water heaters, etc.).
Design
The Duo DFR is designed as a manual back-flushing filter in connection sizes DN 20 - DN 25. The integrated pressure-reducing valve protects the installation from excessively high pressures and pressure surges. The cascade-shaped filter insert is made of plastic.
Maintenance
The required maintenance is indicated by a maintenance indicator on the top of the filter. However, DIN 1988 requires that the filter be backwashed at least every 2 months. No special tools are required to maintain the Duo DFR. To maintain the filter, open the ball valve and turn the lower part of the filter 2-3 turns to the left or right. Then close the ball valve again. The water supply continues with filtered water even during backwashing.
