The automatic breather produces   possible aerial inclusions and gas inclusions. The pollutions are held back   within the filter cartriges and generate an increasing flow opposition. As soon   as a pressure difference opposed in the difference push button switch reaches   or a preselected time has run out, becomes the automatic one own medium   back rinse released. The back-washing rotor goes without business   interruption successively under everybody filter cartridges, so that with at the   same time open back-washing valve all filter cartridges successively by   current return with filtered own medium back-rinsed become.   After a full rotation of the back-washing rotors is the process finishes and   closes the back-washing valve.   Picture Index   1 Hole plate           5 Automatic venting unit   2 Filter cartridge    6 Differential pressure indicator   3 Washing rotor    7 Back washing-valve   4 Engine                 8 Housing lid  Elasto-Wedge Wire Cartridges   Breathing Elasto wedge wire cartridges have precisely defined   filter column, which to itself with the back-washing flow grows.   Thereby if become also stuck border grain particle as well as   fibrous one suspended matter and solids strictly back-rinsed and   do not lead to blockage to be remained. Back-washing filters   with these to dynamic filter elements are extremely reliable in   service and maintenance-free.   Filter micron rates: 50 µm to 1 mm   Material: Polypropylen  V-Wedge Wire Cartridges   Stiff V gap-filter cartridges are respectable standard elements   with to exact V-shaped filter columns, before which to itself them   to pollutions to be produced deposit. By the back rinsing in   reverse direction becomes in the V columns a high   back-washing flow generates, so that before him filter columns   to mature solids reliably are removed.   Filter micron rates: 50 µm to 3 mm   Material: High-grade steel
