Corning® Ceramic Particulate Filters

Corning® Ceramic Particulate Filters

Monolithic Design and Advanced Material Compositions

Corning® DuraTrap® filters offer monolithic design and advanced material compositions to optimize pressure drop, filtration efficiency, durability, and system cost. They are designed to trap soot, or particulate matter, from diesel or gasoline exhaust emissions in a variety of light-duty and heavy-duty applications. Alternate channels are plugged to force exhaust through the pores of cell walls, leaving behind soot particles that are too large.

Our Products

Light Duty: An Innovation For Cleaner Air

Corning®
DuraTrap® AT filters

For proven perfomance
in light-duty diesel systems

Corning’s aluminum titanate (AT) filters combine a low coefficient of thermal expansion (CTE) with high heat capacity to deliver important benefits, all made possible by an advanced material composition and monolithic design.

Corning®
DuraTrap® AT LP filters

For next-generation
light-duty diesel systems

Using our signature monolithic design rather than segmented construction, our lower porosity filter option enables low pressure drop or high soot mass limit for flexibility in meeting customer requirements.
