A Diesel Particulate Filter (DPF) is a device designed to remove diesel particulate matter (DPM) or soot, from the exhaust of diesel engines. Diesel particulate filters can remove roughly 85% of the soot found in diesel emissions and can at times, depending on the filter and other equipment it is paired with can attain 100% soot removal efficiencies.

 



Diesel-powered vehicles which are equipped with a DPF emit no visible emissions from the exhaust pipe and far less harmful not only to the environment, but to the general health of those in the vicinity of the running vehicle.

 



Purifilter Passive RegenerationPurifilter™ Passively Regenerating DPF

  • Our industry leadership doesn’t stop with our DOC technology, the Purifilter™ was the first passively regenerating DPF to attain an industry leading 90% PM emissions reduction credit value*. Purifilters are more efficient as they are manufactured with Silicon Carbide substrates which offer superior filtration and durability compared to other DPF materials.

  • The Purifilter employs a base and precious metal catalyst impregnated onto the silicon carbide DPF surface to passively oxidize accumulated particulate while complying with stringent California Air Resources Board (CARB) limits on NO2 emissions.

  • The bottom line is that your investment in Purifilter™ delivers the most effective, durable and quiet solution to your environmental mandate.

Combifilter™ Actively Regenerating DPF

Combifilter™ Type S

Combifilter™ Type K

 

 

  • The Combifilter is an actively regenerated DPF system that typically removes 90+ % of PM* while reducing NO2 emissions. The system is comprised of an integrated DPF and silencer assembly, and an off-board regeneration control panel or station.

  • Un-like passively regenerating DPF’s, Combifilter equipped engines do not have to meet minimum duty cycle requirements. Regardless of how you operate, a Combifilter allows certainty and peace of mind in your operation.

  • Depending on the Combifilter™ you choose, simply plug your Combifilter™ equipped vehicle in when you’re on lunch or when the days work is done and your equipment will always be ready for a day’s uninterrupted work.

  • Combifilter™ Type S regenerates or self cleans in 60 to 90 minutes.

  • Combifilter™ Type K regenerates in eight hours or overnight.

  • Unable to tolerate any equipment downtime? A Combifilter exchange system allows you to swap out a dirty filter for a clean filter in two minutes. Then the dirty DPF can be regenerated off-board at your convenience without tying up the equipment. In addition, the off-board regeneration equipment can be used to service the filters from several pieces of equipment.

  • A Combifilter offers flexibility- With input on your operation, Engine Control Systems will determine which Combifilter™ system is best for your application. With various systems available for various applications, the Combifilter™ system can be tailored to meet you PM reduction needs.

     

purifilterPurifilter™ Plus


The Ultimate Solution combining the benefits of Combifilter’s active regeneration with Purifilter passive operation

 


 

  • Purifilter™ Plus combines the benefits of Combifilter’s active regeneration with Purifilter’s passive operation to provide the combined benefits of both products

  • Purifilter™ Plus employs a passive Purifilter DPF to allow extended periods of passive operation with periodic active regeneration at a optimal interval determined for your equipment (i.e. weekly, biweekly, every preventative maintenance, etc.) to

    • increase Purifilter™ tolerance of duty cycle variations

    • provide a proactive fleet management / maintenance tool that insures equipment availability / up-time, low backpressure, fuel economy, and ease of on-board service without DPF removal

    • reduces infrastructure investment by allowing regeneration equipment to be used to support a wide number of Purifilter installations

    • truly eliminates the need to remove DPF’s except for de-ashing at 1500 engine hour intervals.

  • Purifilter™ Plus is the perfect solution for high utilization fleets (i.e. cargo handling at ports) or rental construction fleets who need a quick way to insure the condition of DPF’s installed on rental equipment to a wide variety of customers with different equipment uses.
