Automatic self-cleaning disc filtration equipment Rain Bird disc filter is a type of irrigation filter, similar to a screen filter, except that the filter cartridge is made up of a number of discs stacked on top of each other like a pile of poker chips. The filtration element consists of grooved discs, mounted on a spine, forming a cylindrical filter element. The water passes through the small grooves in between the discs which are compressed together by a spring located at the bottom of the filter cover and the impurities are trapped behind. Disc filters can be backflushed in such a way that the discs are able to separate and spin during the cleaning cycle.
