Abstract: A filter unit (100) includes a rigid filter block (1) that filters out a gas or particles from a gas mixture flowing through the filter unit (100). The filter block (1) has two end faces (Sf.a, Sf.e) and a shell surface (M). A housing including a pot (4) and a cover (2) surrounds the filter block (1). The pot (4) includes a base (4.1) and a tube (4.2). A gap (Sp) occurs between the tube (4.2) of the pot (4) and the shell surface (M) of the filter block (1). Between one end face (Sf.a) of the filter block (1) and the base (4.1) of the pot (4) there is a flat inner area (3.1) of a deformable damping layer (3). An outer area (3.2) of the damping layer (3) surrounds the inner area (3.1) in a circular ring form and is located in the gap (Sp).

Abstract: A device for gas analysis includes a detector tube (2) and can be used in the area of explosive or combustible gases. A filter material, which consists of a granular, porous material and has an impregnation for absorbing toxic gases, is provided between the detector tube (2) and a pump (6).

Abstract: A sorption agent comprising activated carbon and an impregnation of the activated carbon for the sorption of air pollutants, wherein the impregnation contains a zinc compound and a molybdenum compound, as well as a gas-filtering element, such as a respirator canister, containing said sorption agent.
