Industrial Sewn End Filters

About Industrial Sewn End Filters

Industrial sewn end filters are an industry standard used in the most difficult applications, where chemical compatibility and temperature concerns dictate the style of filter. Sewn end filters are typically constructed of carbon steel. Galvanized perforated steel sheet metal is rolled to form the rugged inner core, and is then welded to a steel frame or skeleton. The skeleton is made from pleated woven wire which supports the sewn pockets or pleats of the textile media. The textile media covers the skeleton and gaskets. A second layer of wire mesh can be pleated to, or placed around the outside of the media, for more rigorous applications and backwashing environments. Stainless steel parts and high-temperature medias are also available for use in aggressive environments. Backwash screen is one of the most common options for sewn end filters. Backwashing screen may be needed if the application has a reverse fluid flow; where the flow direction is from the inside-out. Backwash screen is designed to extend the life of the filter element by preventing the textile media from being pushed away from the inner core. Sewn end filters may be Sanobonded, stitched, or glued with adhesive depending on the media and intensity of application. Sewn end filters extend the life of vacuums, pneumatic controls, meters, and other pipeline equipment by trapping particulate, absorbing moisture, and preventing contaminants from progressing downstream.

Sidco’s sewn end filters are effective in removing up to 98% of particulate and contaminants from air, gas, and liquids.
