Applications

The Indoor Air Quality Filtration System combines particulate and gas filters to remove pollutants prior to entering residences and commercial buildings through mechanical ventilation and heat recovery systems (MVHR).

The Indoor Air Quality Filtration System is designed to bring outdoor air pollutant levels within the guideline exposure limits as set out in Air Quality Guidelines. The Indoor Air Quality Filtration System offers a mitigation solution for use in new build properties where a planning requirement to address Indoor Air Quality (commonly Nitrogen Dioxide levels) is required.

Pollutants that are controlled with the Indoor Air Quality Filtration System include NOx, Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Ozone (O3), VOCs (Volatile Organic Compounds, and Particulate Matter (PM10 and PM2.5).

Particulate Matter Filter, PM10, PM2.5

The Indoor Air Quality Filtration System can house up to two particulate filters taking out PM10 (Particulate Matter below 10 microns), and PM2.5 (Particulate Matter below 2.5 Microns).

Panel Filters of Grade G4 to EN779 come as standard in all systems and have an arrestance above 90% that make it suitable for the removal of PM10 particulates.

An additional particulate filter of Grade F7 to EN779 can be included to further reduce smaller particles (PM2.5) to an efficiency between 70 and 80% at 0.4μm.

Particulate filters typically have a life span of one year before they require changing depending on particulate concentrations in outdoor air.

Pollutant Gas Air Filter, NOx, Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Ozone (O3), Volatile Organic Compounds (VOC)

The Type 1 Gas Filters used in the Indoor Air Quality Filtration System are designed to remove pollutant gases at the rated air flow of the filtration system. A specially formulated Activated Carbon and chemical mix acts upon pollutant concentrations common in dirty city air, reducing them below guidelines set by current legislation.

The Gas Stage Filters in the Indoor Air Quality Filtration System are designed to achieve a minimum contact time suitable for the removal of pollutant gases at the rated air flow.

The major pollutants controlled by the Type 1 Gas Filter include NOx, Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Ozone (O3), and VOCs (Volatile Organic Compounds). The Indoor Air Quality Filtration System is designed to bring pollutant levels below Air Quality Objective Concentrations as defined by local authorities.

Construction and Installation Requirements

The Indoor Air Quality Filtration System Housing is manufactured in a pop rivet construction from 1.2mm Galvanised Steel together with suitable sealing for particulate and gas filters. Access is available on both sides via bolted lift-off panels.

The Indoor Air Quality Filtration System can be mounted horizontally or vertically using the fitted mounting bars, and comes as standard with maintenance access on both sides via lift-off access doors. Duct transformations are included within the stated unit length, and are available in circular and rectangular – suitable for both domestic and commercial duct work. (Common spigot connections : 204x60mm / 220x90mm / 150mm Dia / 125mm Dia)

Nitrogen Dioxide Removal Efficiencies

Testing carried out under typical operational circumstances have shown that the Indoor Air Quality Filtration System using Type 1 Gas Filters will reduce Nitrogen Dioxide concentrations below EU Directive limits of 40μg/m3 when challenged with concentration levels up to 200μg/m3.

Peak reduction efficiencies of Nitrogen Dioxide were measured at 87%.
