Wärtsilä 32 Air Assist Filter

Application Notes

Filtration of air within the air-assist inlet arrangement of the Wärtsilä 32 marine engine. The air-assist filter is identified as 3F03 – Air filter (air assist inlet) in Wärtsilä documentation. Condensate formation after the water separator can create and loosen abrasive rust from the piping, fittings and receivers. Wärtsilä therefore recommends installing a filter before the starting air inlet on the engine to prevent particles from entering the starting air equipment. An Y-type strainer can be used with a stainless steel screen and a mesh size of 400 µm. The pressure drop should not exceed 20 kPa (0.2 bar) for the engine-specific air-assist consumption.
