- 4 high-performance cleanAir odor filters with optimized odor reduction performance for cooking applications with complex odor molecules (e.g. fish). Large scale filter surfaces with high odor reduction capabilities and a lifetime of 360 hours of cooking (nonregenerative). Filters are additionally optimized for low-noise with optimized psycho-acoustics. - A telescopic slider element with integrated sealings and a self-gluing fixation frame to easily connect the appliance’s air outlet with the cut-out in backpanel of the furniture.  This “Plug ‘n Play” installation kit enables very convenient plannings and very convenient and quick installations. A return-flow aperture of ≥400cm² is to be respected in the plinth area. This configuration requires a vertical aperture of min. 25mm behind the backpanel of the furniture. Suggested for ideal performance are 50mm. For recirculation against an external wall we recommend partly or fully ducted recirculation extraction (using Z821PD0).
