AERATION MEMBER, AERATION MEMBER KIT, VENTILATION BASKET USING THESE, AND VENTILATION TANK

摘要

PROBLEM TO BE SOLVED: To provide an aeration member which elongates the time until the haze is caused in the inside of a basket and shortens their time until the generated haze disappears even if the haze is generated in the basket, to provide an aeration member kit and to provide a ventilation basket and a ventilation tank using these.

SOLUTION: The aeration member is provided with a first aeration membrane through which the gas passing an opening permeates under conditions of the membrane being fixed to the opening of the basket or tank, a second aeration membrane and an absorbing layer, a supporter which supports the first aeration membrane and the absorbing layer, and a one-way directional valve arranged so as to cover the first aeration membrane wherein the first membrane and the second membrane are arranged so that the gas permeates independently through each aeration membrane, and the second aeration membrane and the absorbing layer are arranged so that the gas permeates continuously through the second aeration membrane and absorbing layer and the absorbing layer comprises a moisture absorbing agent.
