AAC Nitrosorb® NOx Filter Systems

AAC Eurovent is a market leader in NOx filter technology. AAC Nitrosorb® NOx filters are designed to deliver maximum NO and NO2 reduction. These high-efficiency NOx filters provide the ideal solution to the UK Building Services market for indoor air quality projects in residential, commercial, educational, and transportation schemes.

Air Pollution and the Impact of the Legislation on the UK Construction Industry

The European Union Air Quality and Clean Air for Europe Directive 2008/50/EC stipulates that indoor Nitrogen Dioxide must not exceed the concentration level of 4Oug/m3.

This legislation has significant implications for planners, developers and mechanical consultants who are involved in new build and retrofit projects in the residential, educational and commercial sectors. To comply with this legislation, developers must include NOx filtration in their design.

Areas that exceed 4Oug/m3 are designated as Air Quality Management Areas by local authorities.
