8.3.4 Star ting air filter (3F02)
Condense formation after the water separator (between starting air compressor and starting air vessels)
create and loosen abrasive rust from the piping, fittings and receivers. Therefore it is recommended to install
a filter before the starting air inlet on the engine to prevent particles to enter the starting air equipment.
An Y-type strainer can be used with a stainless steel screen and mesh size 400 µm. The pressure drop
should not exceed 20 kPa (0.2 bar) for the engine specific starting air consumption under a time span of 4
seconds.
