Operating principle
The Filtration Group (ex Mahle) AF 113 G backflush filter belongs to the Vario series. The compact Filtration Group automatic filter system is used for fine and micro-filtration of a variety of low-viscosity liquids.
This inline pressure filter consumes no filter material, which means there is also no need for subsequent disposal. The filter is cleaned without interrupting operation. The concentrated solids are drained off simply by opening the system for a short time.
The medium to be cleaned is guided into the filter housing under pressure and flows inward through the Filtration Group segmented element. Particles settle on the surface of the filter medium. The filtered fluid exits the filter housing at the top opposite the inlet connection.
The integrated preseparator relieves the load on the segmented element, particularly from coarse and heavy particles. This is achieved by a tangential flow around the preseparator tube and the deflection edges.
The filter is cleaned when a preset differential pressure limit, a set interval or a defined filtered fluid quantity is reached. The segmented element is turned as the cleaning valve is opened. The segments are then guided one at a time past the flushing channel on the outer circumference, causing them to open and close alternately. The internal pressure is built up at a throttling point downstream of the filter, so that when one segment opens, an outward surge cleans the separated particles from the filter material. As a result of this pulse cleaning principle, the particles are catapulted out, collected in the flushing channel and discharged with a small amount of internal medium. One turn is sufficient to clean all segments. The residue that has settled in the collection cone can be emptied via the drain valve either when the machine is at a standstill or during filtration.
All filters of the Filtration Group Vario series are protected by various patents.

The curves represent the volumetric flow through the entire filter system (filter housing including one filter element as an example) and refer to a differential pressure of 0.3 bar. Specific information about process data is essential for reliable operation of automatic filters.
