The semi-automatic mixed filters of dozhdevalny cars of ORSIS (Aut).

A series of the filters cleared in the course of a running cycle of ORSIS (Aut) M106S, M128S.

Water passes through the entrance punched filter then through the mesh filter of thin cleaning. Both filters are divided by the rough polymeric screen. Particles of dirt remain in a trap in the screen.

For cleaning of the filter the drainage valve opens. Then via the pipeline of withdrawal of dirty drains in special capacity the discharge of a filtrate from system is made.

Cleaning of the filter is made by turn of the special handle clockwise. Return of the working cleaning elements to an initial state is made counterclockwise. Thus, the soaking-up nozzles of the working cleaning elements move on a spiral along the screen. The taken particles are washed away via the discharge crane. This process repeats until pressure on an entrance and an exit are not balanced as at start of system.

Cleaning of the filtering element is made during process of a filtration without interruption of water flow via the filter
