Sidco Replacement Elements  Sewn End Filter CONSTRUCTION Supportive inner cores are regularly fabricated of galvanized perforated sheet metal. Galvanized wire mesh is pleated to support the textile media. For more rigorous applications, a second layer of wire mesh is placed on the outside of the pleated textile media for back washing environments. Textile medias are available in a variety of micron ratings and efficiencies. Some commonly used are polyester felts, nomex, and fiberglass. UNIQUE FEATURES The textile media is cleanable at the job site. Sewn end style filters are used in applications where chemical compatibility and temperature concerns dictate the style of filter. For more aggressive environments, this style can be constructed with stainless steel parts and high temperature medias.
