Abstract

1466713 Gas filter; gas absorber AIR INDUSTRIE 5 June 1974 [6 June 1973] 24844/ 74 Headings B1L and BIT A gas filter element comprises a plurality of cells filled with granular or particulate material, e.g. active carbon, zeolites or soda lime, wherein the cells each have perforated walls 1, connected by bracing members 10 and 11 inside the cells. The cells are arranged in pairs, and the pairs sealed in the filter by adhesive, each pair defining a dihedral angle and having inside each cell elastomeric material 13 to hold the particulate material in position. When the cells are to be filled the plate 14 is pulled downwardly compressing the elastomeric material 13, (Fig. 5 not shown) and after filling plate 14 is released, (Fig. 6 not shown), the material 13 then exerting an upward pressure on the particulate material. Bracing members 10, 11 carrying a baffle 12 prevent walls bulging outwardly under pressure.
