Regeneration of the DPF filter is the process that burns the soot accumulation inside the DPF filter. An unmaintained DPF makes your vehicle run harder and less efficient, causes sluggish acceleration, reduces fuel mileage, and even leads to engine derate and shutdown. Taking your equipment to a repair shop for DPF regeneration will cost you $500-$2000 per time. FCAR F804 can help you complete professional forced DPF regeneration by yourself, restore your equipment power, save a lot of maintenance costs and downtime.
Solve DPF filter clogging issues, eliminate engine derate, restore full engine power and acceleration performance, ensure your construction machinery has enough power for heavy duty work.
Avoid $500-$2000 per time repair shop fees, long-term savings are enough to buy a new equipment. Also save towing costs and downtime caused by sending equipment to the workshop.
Regular DPF cleaning can improve MPG, optimize fuel efficiency, reduce fuel consumption, bring better throttle response, reduce passive regeneration frequency, extend DPF service life.
Support DPF reset, clear DPF related fault codes, turn off DPF regeneration MIL, reset DPF life cycle after filter replacement or maintenance, meet emission standards.
