The international trend towards the introduction of energy-saving regulations strengthens the requirements for energy efficiency for both new buildings and for renovated buildings. A high efficient insulation of the building, e.g. built according to Green Building Standard, accompanied by tight sealed building shells. Decentralized ventilation units take over in addition to the heat recovery also out a substantial contribution to the reduction of fine dust and allergens in the interior from the outside air and filters beforehand. Decentralized ventilation units from AiolosAir® are therefore perfect for air exchanging and for removing excess humidity as well pollutants in the air. They are therefore an important part of a healthy indoor climate and at the same time an active and sustainable contribution to environmental protection . The decentralized ventilation system Family of AiolosAir® is already adapted to the typical room sizes in residential construction. Depending on the definition of air quality comfort conditions, a device for room sizes 10-25 m² can be regarded as average. Little installation effort enables low installation costs and accurate cost planning. Air ducts for transporting the air are not required for decentralized devices. Complicated pipe network calculations while planning may be omitted as well as comprehensive maintenance and cleaning work on the canal system after commissioning. In addition to the typical application in housing construction, student residences and senior centers, is the use of WRG Plus devices in hospital bed rooms, doctors' offices, office buildings, schools and kindergarten, in particular to ensure the basic ventilation in particularly tightly sealed buildings. To ensure the minimum air exchange for protection against moisture, especially recommended ... The advantages of decentralized ventilation technology are obvious - we support you in the realization of your project!
