Diesel Particulate Filters

Protect Your Fleet and Reduce Emissions

Demanding applications require products that outperform. CDTi’s family of DPF technologies provide superior emissions control, noise attenuation and lower exhaust restriction over the broadest range of diesel engines. All DPF products are produced with a Silicon Carbide substrate, which is the most durable material available. Each DPF kit is provided with a back pressure and temperature monitor, independent of the engines ECM. With Verifications by the US EPA, CARB & VERT, you can depend on performance and reliability

CDTi has a tailor made product ready for any application. Whether that be for heavy duty truck, construction, mining, material handling or stationary power. Please explore the links below for more information on our retrofit technologies based on the application.

Purifilter™

Purifilter™ is a ceramic DPF that is revolutionizing the way diesel engines perform and impact the environment. Its innovative design and construction deliver exceptional benefits, including:

 

  • Minimal potential failure points and unit installation time, getting your equipment back in service faster.
  • Extremely low soot oxidation temperatures, making it ideal for a variety of on- and off-road applications, such as cold climates or in applications where engines can’t operate efficiently at high temperatures.
  • A durable, long-lasting Silicon Carbide substrate to remove 98% or more of the particulate matter from the exhaust gases, which helps reduce emissions and improve air quality.

Purifilter Plus M™

The Purifilter Plus M™ is a ceramic diesel particulate filter (DPF) that uses a revolutionary combination of passive and active regeneration to reduce emissions.

 

Unlike other DPFs, it doesn’t require connections to the ECM or fuel sources, making it a reliable and easy-to-install option for a wide range of applications, including:

 

  • On-road vehicles
  • Off-road vehicles
  • Military vehicles
  • Stationary engines
  • Marine engines
