The vegetable oils currently on offer, especially the cold-pressed oils, often contain residual substances that can lead to malfunctions in the normal fuel filter and to poor combustion with far-reaching consequences. The excellent properties of the MO filter provide a technical improvement and more safety here.

Fuel oils are also often contaminated due to aging processes and tank cleaning that is not carried out frequently enough, which leads to filter blockages and burner failures. By using the fuel filter, these contaminants are bound and malfunctions can be avoided. However, the main advantage of the MO filter in heating oil operation is the better atomization of the fuel, which leads to longer burner runtimes and a reduction in consumption.

The MO filter is installed in the fuel circuit upstream of the factory filter technology in a vertical position with the connections facing upwards. The fuel filter should be located in a warm place in the engine compartment. Due to the finned structure of the housing, the MO filter acts as an additional heat exchanger to the fuel.

As a depth filter, the MO filter has a high dirt-holding capacity. Nevertheless, the cartridge should be replaced every 30,000 kilometers or during normal service. To do this, unscrew the cover with the connections and pull the cartridge out upwards.
