GAS ADSROBING AIR FILTER

摘要

PURPOSE: To provide a compact air filter efficiently adsorbing gas and collecting dust. CONSTITUTION: This gas adsorbing air filter is constituted by inserting a gas adsorbing member 22 in the space between the adjacent filter materials 11a of an-air filter formed by folding a filter material 11 in a zigzag fashion. An adsorbent 18 in each of capsules 16 and the gas in air is adsorbed by the adsorbent 18 while air is allowed to flow along those capsules from the inlet of the gas adsorbing air filter and the dust in air is collected by the filter materials 11a during the passage through the filter materials 11a and the adsorption of the gas is again performed on the outlet side 25 of the filter during the flow of air along the capsules 16.
