Sentinel filter bags

Sentinel filter bags meet the requirements of liquid filtration applications that have a zero tolerance for filtration bypass. Manufactured using a unique fabric-welding technology, as opposed to sewing, these filters have no needle holes that allow unwanted particulate matter to bypass the filter bag. This process also enables the manufacturer to shape the bags to conform to the internal shape of the filter basket, preventing bag failure. The bags come standard with a patented plastic ring that makes a secure, bypass free seal between the filter bag and the filter housing. The design of this seal creates a constant, radially directed pressure to prevent the ring from collapsing into the filter basket. Sentinel filter bags are available with either polypropylene or polyester construction in both double-length, 7-in.× 32-in. number 2 size, and single-length 7-in. × 16-in., number 1 size, to fit filter housings from most manufacturers.
