MOISTURE ABSORPTION RESPIRATOR

PROBLEM TO BE SOLVED: To provide a moisture absorption respirator in which cassette type moisture absorption containers are formed to make the replacement work of a moisture absorption agent easy, the volume of the moisture absorption agent is adjusted simply and the respirator is divided into a filter and an indicator to improve the replacement workability. SOLUTION: A moisture absorption respirator is constituted of moisture absorption units 15 in which connecting fitments are installed on the side faces of plane plate-shaped blocks 20, moisture aborbent storage containers 21 are connected on one faces of the blocks 20, ventilation pipes 28 communicated with the containers are protruded from the blocks 20 and socket sections 31 are formed, an indicator 18 in which a connecting fitment is installed on the side face of the plane plate-shaped block 20 and a hollow cylindrical section 34 is formed inside the fitment in which a flapper 36 varying its position in compliance with the air flows is installed, and a filter unit 17 storing a filter material 41 in a container 39 with an air vent 38 opened downwardly, and above-referred respective units are fitted removably and connected one another in a manner of cassette type.
