Corning DuraTrap - - AT LP Filters - Particulate Filters for Diesel Systems Brochure

Vehicle and engine manufac-turers worldwide are striving to improve the fuel efficiency and performance of diesel engines while meeting particulate mass and particulate number emis-sions limits. Corning® DuraTrap® AT LP filters help our customers meet their objectives.Next-generation Corning DuraTrap® AT LP 300/10 and Corning DuraTrap® AT LP 300/13 filters are designed with a lower porosity and optimized micro-structure to enable product designs for low pressure drop or high soot mass limit. Clean Diesel Made PossibleParticulate filters for next-generation diesel systems Corning® DuraTrap® AT LP Filters Corning DuraTrap® AT LP 300/10 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 for High Soot Mass Limit Higher thermal mass:• Reduces regeneration frequencies and fuel consumption• Increases thermal and mechanical robustness for higher soot mass requirementsNext-Generation Product Benefits* DuraTrap® DuraTrap® DuraTrap® AT 300/13 AT LP 300/10 AT LP 300/13Pressure Drop Base -20-25% =Soot Mass Limit Base = +2-3 g/lFiltration Efficiency Base = = 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 asymmet- ric cell technology (ACT) is an option that helps manage lifetime pressure drop requirements and provides ash storage benefits through larger inlet channels.
