A fluid filtration device includes a tubular external shell assembled with first and second end plates. A cartridge plate is secured to the shell between the first and second end plates, such that the first end plate and the cartridge plate define a filtration chamber, and the second end plate and the cartridge plate define an outlet chamber. The cartridge plate includes a plurality of apertures configured to receive a plurality of filter elements assembled thereto. An inlet port intersects the filtration chamber, and an outlet port intersects the outlet chamber. The cartridge plate is secured to the shell by a laterally split, outwardly resilient retaining band received in interlocking engagement with a corresponding inner circumferential groove in the shell, the inner circumferential groove being positioned adjacent to the cartridge plate, such that the installed retaining band prevents longitudinal movement of the cartridge plate toward the second end plate.

Fluid filtration system

A molded plastic vessel is provided with a fitting or other attachment after molding and before winding of the vessel. The fitting is provided with a plastic insert. The insert and a wall of the vessel are heated and welded together to hold the fitting on the vessel. The tank is filament wound for reinforcement, and the filaments capture the fitting to hold the fitting on the wall. The wall is opened to provide a passage through the fitting into the vessel. An apparatus is provided that carries and moves the fitting, insert, and a heater to install the fitting on the vessel.
