Installation-Set

The final assembly set consists of a Ventomaxx high-performance ceramic heat exchanger. These are designed to be closed-cell, insulation-free and therefore absolutely VOC-free. They are therefore considered unique in terms of air hygiene and can be cleaned permanently and wear-free, even by machine.

The second component of the final assembly set is the digital fan unit, characterised by a quiet, energy-saving EC fan with integrated sound insulation.

The PLUS DESIGN panel on the room side is fully thermally insulated and has an adjustable air outlet roller with adjustable air flow. The filter can be changed without tools.
