H. Principle ofoperation Automatic Metal Edge Filter with radial cleaning device Pi casted version G for liquids, pastes and similar media Connection size G, flange DN and DN The MAHLE metal edge filter system is used for filtering and homogenising a wide range of liquids, wastes and such like. This compact in-line filter requires no maintenance, nor is there any need to dispose of the auxiliaryfilter media. It can be cleaned fully or semi-automaticallywithout having to interrupt operations. The liquid flows from the outside inwards through the MAHLE filter cartridge.the filtrate is discharged at the top, opposite the in-flow connection point. Solid matter, etc. is separated on the triangular profiled winding on the filter support tube. The MAHLE filter cartridge is cleaned by rotating against a scraper blade. The special shape of the edge gaps serves to facilitate a very effective cleaning process. The patented AKF system prevents high axial forces, ensuring that the cleaning process runs easily. The residue deposited in the collection cone can then be emptied through the drain valve while the system is switched off or while it is in operation.. In-flow connection point. In-flow chamber.

We recommend thatcleaning take place atabout four times the initial p. The motor can also run permanently at short filtration phases (rotating the drive shaftclockwise). Cleaning time/engine running time s(=^ approx. rpm). Depending on the residue concentration, the drainvalvev can be opened fordrainage purposes synchronouslywith the startofthe cleaning process or bymeans oftime orcycle control.
