NOx-Nitric Oxide (NO) and Nitrogen Dioxide (NO2) Filters

Indoor Air Quality Filtration Systems

Air Pollution from diesel exhaust fumes can have a serious impact on the health and wellbeing of those who live and work in our cities. With many of our local councils declaring all or part of their borough as designated Air Quality Management Areas (AQMAs), there is an urgent need to source reliable and effective mitigation solutions for common air pollutants such as NOx (NO and NO2), PM10 and PM 2.5.

Indoor Air NO2 Mitigation and Current Legislation

Commercial NOx RemovalThe EU Directive 2008/50/EC (the CAFE Directive) European Union Air Quality and Clean Air for Europe 2008 set stringent NO2 levels for designated Air Quality Management Areas. This has significant implications for Developers, Planners and Mechanical Consultants who are engaged in new build Residential and Educational schemes where NO2 concentrations exceed the accepted level of 40ug/m³

Our competitively priced Indoor Air Quality solutions, based on the independently tested AAC NITROSORB®, deliver high performance NOx -Nitric Oxide (NO) – Nitrogen Dioxide (NO2) mitigation for Indoor Air projects in Residential, Commercial and Educational buildings.

AAC NITROSORB® uses breakthrough technology to deliver sustainable NOx reduction. This unique solution, which is designed for economy and performance, is widely recommended by Air Quality Consultants and is regularly specified by Mechanical Consultants for Indoor Air projects in Air Quality Management Areas (AQMAs).

AAC Swiftpack® NITROSORB® Filter System

The AAC Swiftpack® NITROSORB® Filter System incorporates AAC NITROSORB® media into the AAC PR range of media filter cells to deliver a high-performance solution that is compatible with Mechanical Ventilation Heat Recovery systems (MVHRs).

The AAC Swiftpack® NITROSORB® Filter System offers the benefit of longevity, alongside low pressure drops, with no increased energy consumption from the indoor ventilation system.

A custom design and manufacture service is available to provide different sized units to suit multiple flow rates.


NOx (NO & NO2) Filters for Horizontal and Vertical Air Flows

NOx filers for residential buildings

The AAC Swiftpack® NITROSORB® Filter System is compatible with horizontal and vertical airflow designs. These compact units are suitable for a wide range of volume flow rates and can be made to present a low profile suitable for installation into a false ceiling void as low as 180mm.

The AAC Swiftpack® NITROSORB® Filter System meets the low pressure drop requirements of Mechanical Ventilation Heat Recovery units (MVHRs) installed under part F of the Building Regulations. PM10 or PM2.5 can easily be removed by the installation of a suitably rated particulate pre-filter, thus enabling them to comply with the particulate aspect of the legislation.

NOx (NO & NO2) Filters for Centralised Air Handling Plant

For projects with Centralised Air Handling plant the AAC NITROSORB® filter cells can be installed by means of the AAC Swiftkit® or the AAC Skeleton-Frame.

AAC Swiftpack® NITROSORB® Filter System with Colourcell®

The unique AAC Colourcell® Media Filter System is a patented transparent filter cell which contains a specially formulated media designed to changes colour from white (New Media) to pink when the AAC NITROSORB media is spent.

This provides end users and maintenance technicians with a clear indication of the status of the NITROSORB® media and to when a media replacement project should be carried out. The results can of course be further verified by analysis of a media sample in the laboratory.
