Introduction
The Corning DuraTrap® AT filters are designed for high-efficiency and high-durability applications in light-duty vehicles, particularly those with diesel engines. These filters aim to enhance fuel efficiency and performance while reducing emissions.

Specifications
The DuraTrap AT filter features an advanced material and monolithic design, providing high filtration efficiency and excellent pressure drop performance. It is suitable for both catalyzed and uncatalyzed applications.

Monolithic Design
The filter's design utilizes a low expansion and low elastic modulus material, allowing it to be constructed as a single-piece monolith. This design ensures reliable and durable performance under demanding conditions.

Material Composition
The filter uses stabilized aluminum titanate, which offers outstanding thermal performance. This material provides low thermal expansion and high volumetric heat capacity, enhancing thermal management.

Pressure Drop Performance
Optimized porosity in the DuraTrap AT filters ensures excellent pressure drop performance while maintaining filtration efficiency greater than 90%. This performance is comparable to silicon carbide filters, minimizing the impact on engine power output.
