Abstract:
A filter cartridge for filtering particulates from fluid in a fluid system, said filter cartridge comprising:filtration means comprising filtration media for providing a predetermined particle filtration efficiency and conductive media for drawing off static charge in the fluid, conductive end cap means bonded to and supporting at least one end of said filtration means, said end cap means having a central opening for receiving a tubular housing portion in the fluid system,conductive resilient elastomeric O-ring sealing means retained and supported by said end cap means and bounding said central opening, said sealing means projecting radially inward of the central opening for sealing against the tubular housing portion, said sealing means in electrically-conductive relationship with said conductive media for providing a ground path from said conductive media to the housing portion, wherein fluid directed through said cartridge passes initially through the filtration media and then through the conductive media and static charge in the fluid can be dissipated through the ground path, anda conductive adhesive mass bonding the end cap means to the filtration means, the conductive adhesive mass in electrically-conductive relation with said conductive media and the conductive end cap means.
