Air is supplied to the air filter via the air suction pipe. Air received in the filter
due flowing through the swirler obtains rotary motion in the annular gap between
the housing and filter element. Under centrifugal force dust particles are thrown
to the housing wall and collected in the dust bin through a slit in the baffle.
Then, the preliminary cleaned air flows through the filter element, where it is
cleaned finally. From the turbocharger the air flows via pipes to the charging air
cooler, where it is cooled, and then enters the engine cylinders.
The air filter is provided with a precleaner on purpose to obtain better air
cleaning and extend the filter element’s service life.
The first stage of the air filter is to be maintained occasionally depending on
operation conditions of the truck. The necessity of filter element maintenance
should be determined by the readings of the air filter clogging indicator located on
the dashboard. Every time the indicator lights up the air filter is to be maintained.
