Application Notes
The Wärtsilä 31 Fine Filter (MDF), designated 1F05, is part of the MDF fuel system. It is a full-flow duplex-type filter with steel net and must be installed as near the engine as possible. Wärtsilä documentation specifies a fineness of 34 µm (absolute mesh size) (β50 = 75, ISO 16889).
Additional Notes
The Wärtsilä 31 Fine Filter (MDF), designated 1F05, is a full-flow duplex-type filter with steel net. The documented design data specify a design temperature of 50 °C, a design flow larger than the feed/circulation pump capacity, and a design pressure of 1.6 MPa (16 bar). The specified fineness is 34 µm absolute mesh size (β50 = 75, ISO 16889). The maximum permitted pressure drops at 14 cSt are 20 kPa (0.2 bar) for a clean filter and 80 kPa (0.8 bar). The filter must be installed as near the engine as possible, and the pipe diameter between the fine filter and the engine should be the same as the diameter before the filters.
