Diesel particulate filter for the removal of toxic particulate matter with low NO2
EnviCat™ DPF
Edition Date :
March 18, 2026
EnviCat™ DPF (Diesel Particulate Filter) catalysts greatly reduce emissions of Particulate Matter, CO and hydrocarbons (HC). The catalyzed wall-flow filters offer efficient emission control at low regeneration temperatures.
Hard-rock and base-metal mines sensitive to NO2 – in particular underground mines – must control vehicle emissions. Diesel Particulate Filters (DPFs) provide a primary means for the removal of toxic particulate matter, while maintaining low emissions of poisonous NO2.
The lower the temperature the DPF regenerates at, the better its overall performance. However, many passive emission control systems require high concentrations of NO2 or high exhaust temperatures to regenerate. Clariant offers a passively regenerating DPF that works across a very broad temperature range.
Product Information
Benefits
- Provides an optimal combination of low-temperature regeneration and low levels of NO2 for passively regenerating filters.
