A cartridge (30) for a catalytic ozone converter (21), useful in purifying cabin air in aircraft (1), the cartridge (30) being in the form of an aluminum honeycomb core (37), a tubular metal shell (34) surrounding the core and affixed thereto, metal rib support members (40) fastened to the shell and to the honeycomb core, and a catalytic coating deposited upon the cell walls of the honeycomb core, the resulting assembly having low bulk density and high deozonification efficiency. The metal rib support members reduce mechanical disintegration and/or delamination of the honeycomb core under conditions of high airflow, vibration, or impact from foreign objects. |
