Abstract
The invention relates to a ventilation device for ventilating shower streams that is configured as an insert, and that may be utilized in a connection of a sanitary fitting, particularly in the connection of a shower head housing. The insert contains at least one water throughput channel connected to a ventilation channel such that air is suctioned in through the ventilation channel when a flow passes through the water throughput channel, ventilating the water stream. The insert may have a receptacle for a flow restrictor. A backflow preventer may be provided in order to prevent water leakage from the exterior end of the ventilation channel.
