With Geberit DuoFresh, we can offer our customers a fresh, hygienic solution for their bathroom. Unpleasant odours are suctioned off at their source – directly from the ceramic bowl without any need of a ventilation system. The air is purified via a recirculation system through an active carbon filter.
The central element of this innovative module is a ventilation and control unit that hides unobtrusively (and saves space) behind the anti-fingerprint coated Geberit Sigma40 actuator plate. An active carbon filter reliably retains odours. The purified air is redirected into the room through openings on the sides of the actuator plate. The odour extraction happens right inside the ceramic bowl via the WC flushing supply pipe, which is connected to the suction unit through a ventilation duct. The unit is compatible with conventional, commercially available ceramic WC appliances. The odour extraction is activated by a button on the upper edge of the Sigma40 actuator plate. The button also toggles to turn off the system. Odour extraction on the unit is set to run for ten minutes.
The Duofix WC element "DuoFresh" for odour extraction recirculation is equipped with a ventilation duct as well as a pre-mounted 160cm long conduit pipe that is directly mounted to the concealed cistern for the electrical connection.
The Sigma40 actuator plate comes with the complete electronic ventilation/ control unit, transformer, insert shaft for in-cistern block and an active carbon filter.
