Abstract

A method of cleaning a filter in a separator device for separating particles contained in an air stream is disclosed, the separator device comprising a vacuum source arranged to normally draw air through the filter, the method comprising simultaneously putting output air from the vacuum source in communication with a clean side of the filter and with the surrounding environment. Also disclosed is a separator device for separating particles contained in an air stream, an electromagnetic valve for use in a separator device, as well as a method of controlling a valve arranged to provide a reverse airflow through a filter in a separator device for separating dust/debris from an air stream.
