Description

Engine: Kubota D1803 (Tier IV / DPF)

Eliminate DPF-related problems on your Kubota D1803 Tier IV engine with this Plug & Play DPF Repair Kit.

Designed specifically for Kubota D1803 common-rail engines equipped with a Diesel Particulate Filter (DPF), this hardware solution completely eliminates forced regeneration, DPF warning lights, engine derate, and power loss caused by aftertreatment system failures.

Built using industrial-grade electronics, the module is fully waterproof and engineered for reliable operation in demanding construction, rental, mining, and industrial applications. Installation requires no ECU programming, software, or dealer diagnostic tools—simply install the module and return your compressor to work.

Portable air compressors often spend long hours idling or operating under variable loads, making them especially prone to repeated regeneration cycles and DPF-related downtime. This repair kit eliminates those interruptions for maximum uptime.
