A filtering and absorbing cartridge contains the cylindrical case, the grating cover with the annular side surface, the sorbent inside the case, the upper and lower meshes holding the sorbent, and the folded filter between the cover and the upper mesh. The lower mesh is designed integral with the case with the aim of unifying the cartridge. The upper mesh is equipped with the fixator designed as the annular surface with the ledges inside and outside connecting with the matching parts at the top of the case and the internal annular side surface of the cover. |
