System comparison

LUNOS ventilation systems are based on a demand-oriented flow through the entire living area. For efficient ventilation, the decentralized fans from LUNOS can be combined into three different ventilation systems. Which ventilation system is the right one depends on the individual requirements of the project and the habits of the occupants. Watch also our video, which explains the individual systems.

01 Exhaust air system

02 System with heat recovery

03 Combined system

01 Exhaust air system

Fans in the bathroom, kitchen, WC or utility room transport the exhaust air either directly into the open air or via exhaust air shafts. The resulting slight negative pressure "pulls" fresh, filtered air through the exterior wall air diffusers into the living and working spaces. With humidity-controlled residential ventilation, a system approved by the building authorities, considerable savings can be made in ventilation heat losses.

02 System with heat recovery

With this particularly efficient system, all rooms in the residential unit are equipped with fans with heat recovery - exactly where they are needed. If you are interested in this type of ventilation, we recommend our proven e² series fans. These are axial external wall ventilators with regenerative heat recovery for living rooms or bedrooms, very well combinable with LUNOtherm or LUNOtherm-S.

03 Hybrid system

In combined systems, at least two different types of ventilation are used together. Combinations of exhaust air units and fans with heat recovery are particularly effective: While the living spaces have constant fresh air without heat loss thanks to heat recovery units, classic exhaust air spaces such as bathrooms, WCs, kitchens or utility rooms can be cost-effectively vented as required. In windowless bathrooms and WCs, such an exhaust air unit is even mandatory according to DIN 18017-3. Click here to see our fans for hybrid ventilation.
