Purifilter® EGR is a passively-regenerating diesel particulate filter (DPF) that is compatible with a variety of EGR-equipped vehicles as well as those without EGR systems.


Exceptional filtration and regeneration efficiency.

Purifilter® EGR uses the silicon carbide filter media from our other field-proven Purifilter® models and augments it with our proprietary Mixed Phase Catalyst (MPC®) technology, an upstream diesel oxidation catalyst and highly-efficient thermal insulation.

As a result, Purifilter® EGR provides up to 85% PM reduction and highly-effective exhaust heat retention for effective regeneration performance at reduced exhaust temperatures.*

Advanced features provide reliability and simplify installation.

Due to its advanced design, Purifilter® EGR offers capabilities that minimize potential failure points and unit installation time versus competitive DPFs getting your fleet equipment back in service faster.

  • 35-80% smaller footprint than leading competitive units
  • Connections to ECMs or fuel sources are not required
  • Approved for use as a single or dual filter in horizontal and vertical configurations
  • Lower external skin temperatures

All these features provide additional flexibility for unit locations offering owners and installers more options to improve the appearance of their DPF installation.

Modular design enables quick servicing.

Purifilter® EGR is self-contained, passively-regenerates and designed to last for the life of your equipment. However, should your Purifilter® EGR ever require service, its modular and accessible design enables the unit to be easily disassembled and its components replaced individually minimizing downtime.

This modular design offers significant advantages over competitive DPF units whose traditional sealed-canister designs require time-consuming removal and replacement of the entire unit including connections to ECMs and fuel sources.
