Odor trap for collection shafts and pumping wells of sewerage systems, comprises chamber with activated carbon outlet filter, through which waste gases pass

摘要

The casing (12) has an inlet opening (17) for entry of waste gases. Its stilling chamber (18) has a second outlet opening (19) for waste gases to leave and enter the surroundings. The cross sectional area of the second opening exceeds that of the first. A filter unit (21) covers the second opening. The gases pass through this, and their odors are absorbed, since it contains an activated carbon filter (24).
