Start Products Accessories Ventilation LD 45

LD 45

The LD 45 decentralized ventilation units are reversible ventilation units with heat recovery. They can be integrated almost invisibly into the external wall of the building. The decentralized ventilation system enables automatic air exchange with heat recovery – without the need to regularly open the windows. During air exchange, part of the heat from the extract air is recovered and transferred to the supply air. The adjustable air exchange helps adapt ventilation to the respective requirements. Optional filters can reduce the amount of pollen and dust entering via the supply air. For balanced operation, the LD 45 requires two units operating in opposite phases for supply and extract air.

Benefits

Almost invisible

Can be integrated almost invisibly into the external wall and is suitable for both new buildings and renovation projects.

Independence

Independence Can be used independently of the heat source.

Controlled air exchange

Controlled air exchange The adjustable air exchange supports the removal of moisture from indoor spaces.
