As a full sound absorbing family offers the series AIR CONTROL A modular ventilation concept for flexible use in new construction and in renovation with automatic control function.
Virtually all components of this innovative ventilation system is invisibly integrated in the outer wall or façade. Here you are more than 15 different mounting types are sound proof with up to 64 dB Dnew, in the opened condition available! From the inner design cover to the outer facade border this air passage series is also extremely variable.
Air-Control sound absorbing air passage units are prefabricated at the factory by specifying based of the project-related terms of a nominal dimensions and can be installed just in time simple and quick.
The comprehensive range of accessories of the sound absorbing ventilators are tailored to diverse operating conditions and also takes account of subsequent requests for changes that can be done without tools largely!
AIR CONTROL sound absorbing ventilators are available as outer wall air outlets (ALD) designed so that you demand-oriented hygiene and contruction physically of air changing and can make without use of primary energy.
The fans operate maintenance free (filter change 1-2 times a year, depending on the outdoor air pollution) and ensure long-term operation.
These properties in conjunction with the low investment costs make this series interesting especially for housing development, senior citizen centers, hotels, student residences, hospitals, etc..
Design and dimensioning of the AIR CONTROL [AC] outer wall air passage
Based on a 0.25 to 0.5times air exchange per hour (average) results as a function of a room size in residential buildings of 20 sqm living space, a required air exchange for Moisture protection between 15 and 25 m³ / h. Here, the maximum air flow rate per outer wall air passage [AC] is planned for reasons of comfort with less than 25 m³ / h at 8 Pa pressure difference.
In order to achieve a controlled air flow which [AC] mostly operated in combination with a central exhaust fan.
Noise technically outer wall air passage are [AC] designed as specified by the sound protection certificate. The Air Control [AC] series offers for that highly sound-insulated ventilation solutions up to 65 dB, Dnew.
Air-Control [AC] versus energy conservation?
When calculating the annual heating requirement in addition to the transmission heat losses are also Ventilation heat loss of a building is determined. Contrary to window ventilation can with the outer wall air passage [AC], the ventilation heat losses are reduced by at least 30%. The specification for the fulfillment of an n50 value during blower door test with more than 1.5-fold air exchange is required.
