DuraLite™ ECB, ECC, ECD

Donaldson’s DuraLite Air Cleaners are tough, non-metallic, lightweight, self-supporting, and completely disposable. They are also easy to install, durable, and reliable.

They are designed to function well under high and severe pulsation conditions found in many applications, especially two- and three-cylinder engines. Vibration-resistant media is potted into molded housings of rugged ABS plastic — so they don’t fall apart as other designs might.

Servicing Intervals

  • Choose either of two types:
    • Scheduled (Miles or Hours). DuraLite service intervals can be integrated into any existing maintenance program.
    • Filter Service Indicator. This method offers the most accurate filter maintenance program, delivering maximum filter life, less machine downtime, and reduced maintenance costs.
    • Washing, cleaning or servicing the filter in any way voids the warranty

Service Indicator Location

  • For proper restriction readings, a restriction fitting tap must be located between the engine intake and DuraLite outlet neck. The tap should be located in a straight section of the intake pipe at least one pipe diameter away from the manifold or any bends, elbows or reducers.

Servicing Tips

  • Do NOT judge the filter on the basis of visual inspection! If it’s doing its job, it should look dirty. DuraLite filter life is longer than you may think. Change the filter only when restriction readings indicate to do so.
  • During filter change out, do NOT leave the inlet ducting exposed any longer than necessary (a few minutes) during service
  • Never wash or clean the unit for reuse


  • Follow your local disposal guidelines for disposal
