NOX 50

Designed to remove outdoor air pollutants including particulate matter and nitrogen dioxide from outdoor air being drawn into buildings through mechanical ventilation.

  • Nitrogen Dioxide Mitigation Solution
    The NOX filter can be used in conjunction with MVHR (Mechanical Ventilation Heat Recovery) systems in buildings where outside air breaches target concentrations of Nitrogen Dioxide. By filtering air entering the building, residents and occupants are supplied with clean air in line with EU Directive Limits. The NOX Filter houses the tested Gas Filter Type 1 which can remove up to 90% of Nitrogen Dioxide, ensuring concentrations are brought below the Directive limits of 40 μg/m3 prior to entering the building.
  • Particulate Matter Filtration (PM10)
    The Gas Filter Type 1 is a uniquely designed combination air filter, fabricated to incorporate an internal PM10 Filtration Membrane filtering up to 90% of PM10 particulates that enter the NOX Filter.

    Product Code: AF70-70-PIR SW

    • Rear and side entry knockouts, integral cable clamp and large mains terminals for 2 x 1.5mm conductors. Easy to wire from surface cables and enables loop-in/ loop-out for supply to other sensors.

    • Elongated fixing slots; simple to position and fix to surface.

    • Passive infra-red; ensures light is switched on when sensor detects movement of heat; therefore lighting is switched off when the area is vacated. There is less likelihood of false triggers compared to microwave which switches on any movement.

    • Integral sensor dust-shield to prevent false triggering.
