Product Attributes

Corning DuraTrap® AT LP 300/10 Filter for Low Backpressure

Thinner walls and low porosity:

  • Allow for better fuel economy, lower CO2 emissions, and higher engine performance
  • Maintain thermal and mechanical robustness that allows for high soot mass limits

Corning DuraTrap® AT LP 300/13 Filter for High Soot Mass Limit

Higher thermal mass:

  • Reduces regeneration frequencies and fuel consumption
  • Increases thermal and mechanical robustness for higher soot mass requirements

Monolithic Advantage

Corning’s aluminum titanate material provides low thermal expansion to enable durable monolithic construction that allows for:

  • Low pressure drop and excellent regeneration efficiency to help improve fuel consumption
  • Increased ash storage capacity and larger filtration surface area compared to segmented filters

Innovative Design

The extrude-to-shape monolithic design can be produced in a variety of sizes and optimized for systems with space constraints and diverse configurations.

Corning’s innovative asymmetric cell technology (ACT) is an option that helps manage lifetime pressure drop requirements and provides ash storage benefits through larger inlet channels.
