Functions

Duct connection – designed for direct connection with D100 diameter ventilation ducts
Backdraft protection – the integrated non-return valve helps protect the room from reverse airflow
Airflow direction control – the damper allows air to move in one direction and reduces unwanted air circulation
Protection against unpleasant odours – helps reduce the entry of odours from the ventilation duct, shaft or other connected rooms
Reduction of cold air entry – when the fan is not operating, the valve can reduce cold air entering the room from the duct
Reduction of dust and insect entry – the closing damper helps reduce the entry of foreign particles or small insects through the ventilation channel

Use

For household users: Suitable for ventilation in bathrooms, toilets, kitchens, storage rooms or garages when it is necessary to reduce the return of air, odours or cold air through the duct.
For electricians / installers: A convenient solution for quick D100 duct connection and installation of backdraft protection in a ventilation system.
For engineers / designers: Can be specified as a simple ventilation system component when airflow direction control and protection against reverse draft are required.
For construction / renovation specialists: Useful when installing or renewing ventilation systems in household and auxiliary rooms.
For commercial premises users: Suitable for small technical, auxiliary, office or storage premises where a simple D100 ventilation duct connection is required.

Advantages

With integrated non-return valve – protects against reverse airflow
Simple installation – connects directly to a duct of the corresponding diameter
Lightweight plastic construction – convenient to transport and install
Corrosion-resistant – plastic does not rust, making it suitable for more humid household premises

Disadvantages

Designed for D100 diameter – not suitable for ducts of other diameters without additional adapters
The non-return valve is not adjustable – airflow control depends on the system draft and valve construction

FAQ

Where is this connector with a non-return valve most commonly used?
It is most commonly used in bathrooms, toilets, kitchens, storage rooms, garages, technical and auxiliary rooms where a duct needs to be connected and reverse airflow reduced.

What is the non-return valve used for?
The non-return valve helps protect the room from backdraft – the return of air, odours, dust or cold air through the ventilation channel.

Is this connector suitable for all ducts?
It is designed for D100 diameter ducts. For ducts of other diameters, additional adapters or a connector of another size may be required.

Is this connector resistant to moisture?
The plastic construction is suitable for standard household ventilation conditions, but during installation it is important to ensure a tight connection with the duct.
