Product Information

The NitroBox NO2 Filter reduces Nitrogen Dioxide (NO2) which is prominently produced by
exhaust gases from diesel engines. Due to this pollution arising in cities and urban areas
there is a need to implement mitigation measures to improve the indoor air quality (IAQ). The
NitroBox NO2 Filter is an effective means of reducing high NO2 levels down to an acceptable
level of 40µg/m

3

as a mean annual concentration level.

The units are fully foam insulated. This reduces duct bound noise and thermal transmission
and helps to avoid condensation build up. Where the unit is installed in very cold spaces or if
the outside air is below -5°C then a custom designed removable insulation jacket is available
from EnviroVent, see Accessories and Spare Parts List.
