Structural Water Filters

Founded in 1954 as “Structural Fibers”, the company originally produced aircraft and defense components. However, that quickly changed when Structural developed a patented process that revolutionized the water treatment market by introducing small composite pressure vessels. Structural quickly became the recognized world leader in pressure vessel technology, later expanding its product line to include larger tanks for industrial applications. In 1999, Structural was acquired by Pentair, the world’s leading manufacturer and marketer of composite pressure vessels, as part of its Water Treatment business unit.
