Fred DPF Cleaner

The FRED DPF makes the cleaning of expensive diesel particulate filters safe, fast and very easy. The machine is designed to effectively remove diesel particulate matter and/or soot from most DPFs.  The FRED DPF Cleaner uses 1200 CFM of air flow to pull diesel soot and other pollutants from the bottom of the filter while simultaneously pushing compressed air at the top of the filter to dislodge soot, ensuring a thorough cleaning. Cleaning DPF’s has never been made so easy, clean and safe with minimal exposure of soot to operators by trapping soot in the waste barrel. This machine can be used in many locations including your shop, garage or even on a mobile service truck.

The FRED DPF Cleaner makes cleaning DPF’s easy allowing maintenance to ensure their equipment is running at peak performance. A clean and unblocked DPF will improve fuel economy and ensure increased engine power.
