Decentralized ventilation LD 30 and LD 45
Healthy living environment – uncomplicated


The models LD45 and LD30 are ventilation systems of the category push & pull with heat recovery. These modells are designed that they can be easily and almost invisibly mounted in the wall of the building. Also the planning effort is eliminated.
The decentralized ventilation system ensures a healthy, energy-saving air circulation without open a window. Instead of opening a window, the ventilation system does this automatically and keeps the warm air in the room. Moisture balance and adjustable air exchange create an individually adapted microclimate.
A special advantage especially for allergic:
Fully automatic ventilation systems hold pollen and dust outside via special filters (optional).

For optimum, balanced operation, two devices (LD 45) operating in opposite directions with regard to their operating phases (supply air / exhaust air) are required. Depending in the total air requirement of the residential unit, usually more than two devices are required.
