Hydro-Clear® Sand Filters

Ultimate reliability in gravity filtration
​The Hydro-Clear® pulsed-bed sand filtration system is an excellent solution when gravity filtration is needed. It features a unique underdrain system and a shallow bed of mono-media, fine-grained sand, a design which permits the filter media to be “pulsed” periodically as solids build up. Filter runs are extended and the filter is automatically kept on-line, despite varying loads, and changing water characteristics.
