ISM Series Sand Media Filters

Removal of Solids Down to 20 Microns

Rain Bird ISM Series Sand Media filters are designed for the most challenging dirty water conditions, and are a high-performance solution for water filtration down to 20 microns. These durable carbon steel filters utilize a 24” vertical side shell depth for removal of organic and inorganic suspended solids for filtering large volumes of water with very little pressure drop and are a long-term value. All Rain Bird industrial media filters utilize our simple backwash system for ease of operation and consistent water quality. The automatically controlled filter system operates for an extended period of time prior to a short backwash cycle.
