Application Notes
Used in the fuel oil system of Wärtsilä 50DF engines and identified as Safety filter (1F03) in Wärtsilä documentation. The filter is a full-flow duplex type with steel net, specified with a fineness of 37 µm (absolute mesh size) and a design pressure of 1.6 MPa (16 bar). Wärtsilä documentation states that the filter should be equipped with a heating jacket and installed as close as possible to the engine
Additional Notes
Wärtsilä documentation specifies the following design data for the Safety filter (1F03): design temperature 150 °C, design flow equal to circulation pump capacity, design pressure 1.6 MPa (16 bar), and a filter fineness of 37 µm (absolute mesh size). Maximum permitted pressure drops at 14 cSt are specified as 20 kPa (0.2 bar) for a clean filter and 80 kPa (0.8 bar) at alarm. Exact dimensions and OEM part numbers should be confirmed against the applicable Wärtsilä documentation and the installed component before ordering or replacement.
