Functioning and purpose
Thanks to the casing, one or more ducting networks can be connected to the filter or the grilles can be installed.
A fan is installed downstream of the filter, thanks to which the intake air enters perpendicular to the drum and exits axially. In this way, the filtering septum stops the impurities which are suspended in the resumed air.
The filter is also equipped with a gearmotor equipped with a rubber wheel. This is necessary for the rotation of the drum, which is managed by a timed command or pressure switch. A special belt transmits the movement also to the trolley of translation of the cleaning nozzles. In this way the nozzles run along the surface of the filter and, thanks to a suction system, clean and regenerate the septum removing the impurities that are deposited there.
