Actifilter DB

Intelligent injection technology for maximum regeneration efficiency.

Unikat® Actifilter DB is a diesel particulate filter system which efficiently removes particulate matter, or soot, from diesel exhaust gas and also functions as a silencer.

The collected soot is burned off using an integrated diesel burner while the vehicle is at idle in 20 minutes. The filter is mounted horizontally in the exhaust system in place of the original silencer. A control unit is installed on the vehicle close to the diesel particulate filter and is connected to the engine's fuel return line and to the engine's battery (24V).

Regeneration takes place in a controlled manner. At a preset backpressure or preset operation time, a dash mounted display indicates to the driver that it is time for regeneration. The vehicle is then driven to a suitable place for regeneration, the engine is left to idle and regeneration is initiated by pressing a button on the display unit.

An optional adapter 12 VDC - 24 VDC for connection to 12 V electrical system is available and the Actifilter DB can also be combined with a CDTi diesel oxidation catalyst to reduce gaseous pollutants such as carbon monoxide (CO) and hydrocarbons (HC).

The filter material in Actifilter DB is the same as is used in the Combifilter® which is tested and approved for use in environmental zones and conforms to the German standard TRGS 554.
