All areas that are equipped with extractor fans have a need for new supply air. Modern, newly-erected buildings are usually insulated in a way that makes it impossible for air to infiltrate through leaks in the brickwork, doors or window frames. To ensure a more pleasant and more importantly hygienic indoor air special supply valves are used. These inlets protect the basic structure of the building from moisture and mould. The ZLEP valves can be operated manually and fully automated (thermostat) without any electric connection and are compatible with all ventilation systems.
