Trimbox NO2 Filter®

Carbon Filter with Pre Filter
FOR USE WITH TITON HRV UNITS

Overview

The Titon Trimbox NO2 Filter® reduces Nitrogen Dioxide (NO2) which is predominantly 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 Trimbox NO2 Filter® is an effective means of reducing high NO2 to an acceptable mean annual concentration level of 40µg/m³.

In addition to outstanding NO2 reductions, the Titon Trimbox active carbon filters also absorb sulphur dioxide, hydrogen sulphide, hydrogen chloride, ammonia odours, volatile organic compounds and solvents.

 

Features & Benefits

  • Effective in reducing pollutants in the home, improving Indoor Air Quality (IAQ) and reducing the risk of Toxic Home Syndrome
  • Low pressure drop
  • Low cost
  • Optional ISO ePM1 55% (F7) filter can be installed to further improve indoor air quality
  • Independently tested by BRE
  • Small compact design
  • Compatible with Titon’s range of MVHR units
  • Fully lined box to reduce duct bound noise and condensation
  • The unit can be installed in both intake air and supply ducting
  • 98% NO2 reduction at pre filter concentrations of ≈ 200μg m3
  • Effective silencer
  • Third party tested for both NO2 and Acoustic reductions
  • ISO Coarse 60% (G4) filter reduces 100% of PM10/35% of PM2.5 particles
  • ISO ePM1 55% (F7) filter reduces up to 95% of PM2.5 particles
