Welcome to NorthWest DPF in Ukiah.

  All Diesel Particulate Filters (DPF) need to be cleaned with regular intervals as a small amount of inert debris (mainly ash and other debris from lubricating oil, engine wear metals and air-induced dust) will remain in the filter substrate. Soot and other organic compounds are removed during operation by oxidation. To ensure that the optimum level of performance is maintained, the filter must be cleaned regularly. The cleaning intervals vary depending on the condition of the vehicle and the duty cycle. Despite service intervals, always clean your filter when a backpressure alarm appears on the panel. Higher temperatures may cause the filter can to split. To clean the filter completely of ash and soot, it is necessary to heat up the filter in a kiln. If the filter is not heated, some soot and ash may remain in the filter causing shorter cleaning intervals. The heating must be carried out gradually and well-controlled to avoid an uncontrolled regeneration causing the filter substrate to go exothermic (burn through of filter channels) or the filter canning to split. If the cleaning intervals of the filter are very short, check the opacity of the engine and if necessary clean injection nozzles etc. Diesel Particulate Filters require more maintenance than catalytic converters. Ash, a byproduct of oil consumption from normal engine operation, builds up in the filter as it cannot be converted into a gas and pass through the walls of the filter. This increases the pressure before the filter. Warnings are given to the driver before filter restriction causes an issue with drive-ability or damage to the engine or filter develop. Regular filter maintenance is a necessity.
