Application Notes

The safety filter (2F05) must be installed before the engine unless integrated in the automatic filter (2F02), as described in Section 7.3.11 of the Wärtsilä 50DF Product Guide. Wärtsilä specifies a duplex filter with steelnet filter elements, a maximum absolute fineness of 60 µm, and a design pressure of 1.0 MPa (10 bar). The maximum pressure drop at 50 cSt is 30 kPa for a clean filter and 80 kPa at alarm.

Additional Notes

The safety filter (2F05) is listed alongside the automatic filter (2F02) and suction strainers (2F01, 2F04) in Fig. 7-3 of the Wärtsilä 50DF Product Guide. Wärtsilä specifies an oil viscosity of 50 cSt (SAE 40, VI 95, approx. 63°C) and a design temperature of 100°C for the safety filter. No OEM part number is specified for the safety filter in the reviewed documentation.
