The OdisMatics Hydraulic Filter Model 851/851B are an automatic self cleaning screen filter.
The filter uniqueness lies in the automatic suction system for cleaning the screen. This system
is operated by the inline water pressure without interfering to the filtration process.
The screen cleaning process is short, efficient, saves water and leaves the screen clean.

A pressure switch activates the self cleaning process. A timer backup guarantees that the time
passed from the last self cleaning process will not be longer than the pre-set value determined
by the user.
