Functional principle of an automatic filter
1
The suspension flows tangentially downwards into the filter
housing.
The cyclone effect cause coarse solids to be sedimented
into the collection cone prior to the actual filtration process.
2
The suspension flows through the segmented element.
The particles contained in the suspension settle on the
outside of the element.
3
The filtered fluid enters the clean side and exits the filter.
4
A cleaning process is started when the maximum differential
pressure is reached (if an optional differential gauge / switch
is installed) or after a preset time.
