Claims

The air filter body 5 can be inserted or replaced. These Air filter bodies are at their end with a close-meshed wire mesh ο the like. provided to prevent the spread of flames. In the Altluftabsaugrolir 6 is a by means of manual drive 7 to "Actuating fan 8 installed, in front of which again a shut-off valve 9 is arranged. Both tubes 2.6 are at their outer outlet put out of the wall appropriate with a grating protection 10 or the like. Mistake. The pipes 2,6 are still inside the basement room connect by a pipe 12 provided with a shut-off valve 11, dae in the pipe 2 in front of the shut-off valve 1 and in the Pipe 6 opens behind the shut-off valve 9. This connecting pipe has the purpose that after the end of the gas attack β possibly still in the outer ends of the pipes 2, 6 located poisonous gases by actuating the fan 8 in the direction acussen to be able to.
