Favourable ventilation without great effort.

Installed directly on the external wall, the DL 50 decentralised ventilation system is ideal for retrofitting and renovation. Particularly when retrofitting building insulation, individual rooms can be ventilated in a targeted manner. The EC fans are particularly quiet and therefore also ensure a high level of living comfort. A cross-counterflow heat exchanger recovers the heat contained in the extract air to heat the outside air. In winter, the anti-icing function prevents the heat exchanger from freezing.

• Targeted, controlled ventilation of individual rooms. For healthy and pleasant indoor air at any time of year.
• Quick and cost-effective installation. Ideal for refurbishment and retrofitting - especially for insulation measures.
• Particularly efficient. Integrated heat exchanger utilises the heat from the extract air to temper the fresh supply air.
• Continuous and cosy heat recovery thanks to constant volume flow.
• Long-term comfort. Quiet fans, low maintenance, attractive service package with extended warranty.
• Guaranteed hygiene - also suitable for allergy sufferers. Effective pollen protection thanks to high filter quality. Prevents mould growth - and makes a valuable contribution to the long-term preservation of the building fabric.
