Claims

[Scope of Claim for Utility Model Registration] (1) A cylindrical filter material made by folding a tetrafluoroethylene resin filter membrane into a pleated shape and forming it into a cylindrical shape; In a cartridge filter comprising inner and outer porous cores made of fluororesin that support a filtration material, and end plates made of fluororesin that are liquid-tightly welded to the upper and lower ends of the filtration material, the inner part made of fluororesin is Fins are formed radially on either the outer peripheral surface of the porous core or the inner peripheral surface of the outer fluororesin porous core in correspondence with the pleats of the filter material, and the fins are inserted between the pleats. A fully fluororesin cartridge filter characterized by: (2) The all-fluorocarbon resin cartridge filter according to claim 1, wherein the cylindrical filter material is formed by folding a tetrafluoroethylene resin filter membrane alone into a cylindrical shape. (3) The cylindrical filter material is made by laminating a fluororesin reinforcing material on a tetrafluoroethylene resin filter membrane.
The all-fluororesin cartridge filter according to claim 1, which is formed by folding this into a pleat shape and forming it into a cylindrical shape. (4) A claim in which the cylindrical filter material is made by superimposing a fluororesin porous net support on one side of a tetrafluoroethylene resin filter membrane, folding it into pleats, and forming it into a cylindrical shape. 1. The all-fluorine resin cartridge filter according to 1.
