Abstract

See full text

The adsorption filter has a highly air-permeable, three-dimensional carrier framework essentially stable in shape, to which a layer of granular adsorber particles with a diameter of 0.1 to 1 mm is affixed. The carrier framework can be composed of wires, monofilaments or stays, the distance between them being at least twice as great as the diameter of the adsorber particles. The carrier framework can also be a large-pore reticulated polyurethane foam which has a weight of 20 to 60 g/l and pores with a diameter of 1.5 to 3 mm. In spite of a very slight pressure drop, the filter performance is excellent.
