ABSTRACT:
A recyclable, flexible filter element comprising a tubular, outer braided jacket supported by a helical spring. The bottom of the tube of the jacket is turned inside the helical spring and is sealed by a removable fastening device which is inserted into the bottom of the helical spring to engage the spring through the thickness of the braided jacket. The top of the outer braided jacket is fastened and sealed to a flange and washer assembly which also contains the top of the internal support spring.
Additionally, a method of recycling a flexible filter element comprising the steps of disassembling the sealing element and removing the internal support components of the filter element from the external jacket by disengaging a fastening means at the bottom of the tube. The external jacket can then be refurbished and used with modified internal components. Alternatively, a new external jacket can be provided and used with other existing components of the filter element when the items are reassembled. Reassembly includes positioning the internal support spring within the outer jacket tube, turning the bottom of the outer jacket tube inside the internal support spring and then engaging the fastening means with the bottom of the spring to seal the fastening means to the turned up end of the bottom of the external jacket.
