Odor trap for a waterless or low-flush urinal

摘要

An odor trap has a basin-shaped housing and a collecting basin, which forms an inlet. Inserted into the housing is a siphon which prevents the passage of gas from an outlet to the inlet. A deodorizing insert is located on a screen below the inlet in an essentially dry area. Air ascending out of the siphon flows over the deodorizing insert and is thereby deodorized. The deodorizing insert is located under a cover and can be replaced along with the siphon.
