Introduction As a part of the continuous improvement concept, Wärtsilä can offer an F7 dry filter with better filtration properties and a larger filter area. The F7 filter has a higher particle removal capacity than the standard F5 filter. The F7 filter can be used as an alternative when optimizing air intake filtering plant wise. The F7 filter is of standard size (595 x 595 x 150) and is interchangeable with the F5 filter.

Instructions NOTE: Always stop the engine before performing filter maintenance to ensure no foreign particles or dirt gets sucked into the engine. · Filters needs to be replaced at latest when the ΔP exceeds the alarm limit. · Replace the gaskets when replacing the filters to ensure that there are no air leakages. · The filter housing needs to be thoroughly cleaned and left in good condition to ensure that no foreign particles (sand, rust or similar) enter the turbocharger. · When replacing filters, thoroughly inspect the inside of the ducts and remove any loose parts or corrosion that might enter the turbocharger if left uncorrected. NOTE: Washing the filter bags is not recommended. Cleaning and re-using of filters deforms the structure of the fragile filter material, reducing the filtration rates.
