Hydraulic Suction Scanning Screen Filter

Rain Bird’ IMI+ Series Hydraulic Suction Scanning Screen Filter provides worry free high-flow filtration. IMI+ Series self-cleaning water filters have a parallel flange configured to accommodate simple installation. Models are available as a filter unit only, or as a filter assembly including bypass plumbing and valves for fast and easy installation on site.
IMI+ Series water filters utilize a two-stage screening process. The initial stage consist of a screen for removal of oversized contaminants, while the second stage removes remaining particles, achieving filtration at your specified level. The filter’s backwashing system produces a concentrated high velocity flow to systematically clean the fine sintered screen of any entrapped particulate. The IMI+ Series automatic water filters are used in a wide variety of industrial, irrigation, and municipal applications.
