The primary function is to capture and oxidize particulate matter (soot) from diesel exhaust, reducing harmful emissions in confined underground mining environments to meet regulatory standards and improve air quality.
Common materials include cordierite ceramic, silicon carbide, and stainless steel housing. The substrate is typically porous ceramic or metallic with a honeycomb structure.
Regeneration is the process of burning off accumulated soot. It can be passive, using exhaust heat, or active, via fuel injection. The soot is converted to carbon dioxide, cleaning the filter for continued operation.
Filtration efficiency is at least 95% for PM2.5 (per ISO 19493). Operating temperature range is 200–650°C, with a maximum exhaust temperature of 750°C during regeneration. These are reference values; verify with the manufacturer.
