Diesel Emissions Control Expertise for Heavy-Duty Vehicles
Corning’s broad portfolio of heavy-duty diesel particulate filters can help meet even the most challenging diesel emissions standards. A proven solution, Corning’s filters have been used in millions of vehicles.
An innovative, monolithic design is the hallmark of our product family and Corning® DuraTrap® Filters offer several additional advantages:
- Best-in-class technical expertise from the company that pioneered emissions control systems worldwide
- Extensive product range to address tightening global standards
- Portfolio and attributes enable a wide range of aftertreatment engineering solutions
- Innovative monolithic structure optimizes space utilization
Design Characteristics
Corning DuraTrap AT and AC filters are designed for the highest level of performance.
- Controlled porosity and mean pore size, in addition to thinwall product options, enable high filtration efficiency
- Low expansion and low thermal conductivity provide excellent regeneration performance as well as long-term durability
- Pressure drop performance is enhanced by tailored filter geometry and microstructure attributes
- Large frontal area (LFA) options can improve performance by lowering back pressure and increasing geometric surface area
- Corning’s innovative asymmetric cell technology (ACT) provides ash storage benefits and can help manage lifetime pressure drop requirements
