摘要： A filtering method and a filter device (10) for removing impurities from the breathing air (24) in a room, an air raid shelter or a vehicle. According to the filtering method, the air to be filtered is driven through a carbon dioxide filter (13) by a fan (15), with the result that at least a portion of the carbon dioxide and/or mold spores and other impurities in the air are trapped in the carbon dioxide filter. After the filtering, the filter is regenerated and the carbon dioxide and/or mold spores trapped in it are removed by a technique whereby air heated by a thermal resistor (20) is passed through the filter, this air preferably consisting of the same air to be filtered.

摘要： This device is for balancing air flow and the dispersion of air around duct throats, and is particularly adapted for already manufactured filter modules and ceiling air conditioning diffusers, where concern for spreading fire through the openings is involved. Primarily, it consists of a core assembly for the filter module hood. The assembly includes a mounted bolt and a pair of perforate discs, which will serve as a flame barrier automatically, when fire is present, and the assembly further includes a low melting point solder for its automatic operation.

In a supporting screen for granular filter material, saddle-shaped screen elements borne by the collecting pipe or box are connected thereto or mounted therein in readily releasable manner. In Fig. 1 the collecting pipe 4 is provided with slots 9 which are engaged by hook-like projections 12 on the ends of the saddle-shaped screen elements 11 whereby the latter are held in position. The free ends of the screen elements are closed and may be provided with bearing elements. In Fig. 3, the screen elements 23 extend through the collecting box 21 which has corresponding apertures 22 on opposite sides thereof.

摘要： An NBC filtration system whose main components are a filter unit, a blower, a manual air exchange backup unit and a changeover valve. The filter unit is elongated horizontally positioned along a top portion of a wall of the protected space. Inlet and outlet ports of the filter unit are located close to each other near a first extremity of the filter unit. The blower is driven by the electric motor through a second speed increasing transmission enabling rotation of an impeller of the blower. The blower is positioned along the filter unit near a second extremity distal from the inlet and outlet ports; The changeover valve has a tubular housing extending along the filter unit near the first extremity, and an internal displaceable tubular valve member. Each of the components may be replaced with a component of different capacity without effecting the other components.
