LONGMILE® DPF

The Cleaire LongMile passive diesel particulate filter (DPF) is specifically designed to provide cost-effective diesel particulate matter (PM) reduction for in-use diesel engines operating in on-road applications.

  • CARB verification to Level 3+ (>85%) compliance for PM
  • Designed for diesel engines 5.3-16 liters in displacement
  • Low exhaust temperature requirement enables installation on a broad range of duty cycles, including light or cold duty cycles
  • Low backpressure profile makes the LongMile particularly compatible with EGR engine applications
  • High ash capacity extends filter de-ashing/cleaning interval by 3 times compared to channel wall-flow filters
  • The practical alternative to vehicle replacement. To learn more, download the Dollars and Sense of Retrofits.

The LongMile DPF is managed by Cleaire’s proprietary MLC® which monitors system parameters. The MLC also logs the monitored parameters for later retrieval and analysis.

Cleaire DPFs use only the highest quality materials, including all stainless steel construction and a robust sintered metal diesel particulate filter that provides lower exhaust backpressure than a traditional wall-flow filter. Additionally, numerous inlet/outlet end cone configurations are available for installation ease.

LongMile’s modular design facilitates service and de-ashing of the diesel particulate filter. The reusable metal seal and band clamp design provides quick turn around for maximum up time.

The Cleaire LongMile balances the need for cleaner air with the demanding requirements of real-world on-road diesel applications and the need to maximize the economic life cycle of your equipment while avoiding costly replacement.
