AIR-WC frame type A31, automatic

pre-assembled mounting frame for wall-mounted WC for dry construction

The pre-assembled, ready-for installation mounting frame with radial fan extracts the polluted air directly out of the WC via the flushing pipe. It removes unpleasant odours directly where they arise - the room air keeps being permanently unloaded. With the Air-WC, MEPA has consciously decided for an exhaust air solution which completely discharges loaded air out of the room without a filter and thus without follow-up costs due to filter replacement.

technical drawing


The Air-WC is a product solution which does not yet exist on the market in this combination. That is why MEPA cannot ensure that the solution fully complies with the DIN standards DIN18017 and DIN 1986. Ventilation by means of the VariVIT Air-WC is no replacement of a room ventilation according to DIN 18017 and DIN 1946, but it serves for additional comfort in order to avoid unpleasant odours. The following WC ceramic series are NOT suitable: Duravit Starck 1 IDEAL-STANDARD Mia, Softmood KERAMAG Silk (203670), Plus 4 (202010), Era (208800), 500 Citterio, Med, Cassini, Emani, Flow LAUFEN Vienna Comfort, LB3 Comfort, Liberty Line ROCA W+W VIGOUR Derbi Med +5 VILLEROY & BOCH O.novo (669510). A continuously updated list of ceramics which are currently not compatible with the Air-WC can be found in the download centre under planning aids.
