PROBLEM TO BE SOLVED: To provide a device and method for mounting a new or exchange filter cartridge in a gas filter assembly.SOLUTION: A mounting system for a filter cartridge includes: an upper cap structured so as to be mounted on the filter cartridge; a fitting protrusion part positioned on the upper cap; at least one locking protrusion part protruding radially so as to separate from the fitting protrusion part; and a base part which defines an annular flat surface structured so as to surround the fitting protrusion part on a first side and be mounted on the filter cartridge on a second side. A method of mounting the filter cartridge on the filter assembly includes a step of arranging a locking protrusion part on the upper cap, a step of positioning a spring around the fitting protrusion part, a step of forming an annular groove between the spring and the locking protrusion part, and a step of structuring the upper cap on a part of the filter cartridge.SELECTED DRAWING: Figure 1 |
