## Long description

AWENTA KO100-27/22 wall ventilation collar with built-in non-return valve is designed for connection to Ø100 mm round ventilation ducts and for closing wall penetrations in residential and light-commercial ventilation systems. The unit is finished in white and provides a compact solution for securing duct ends while preventing unwanted air backflow. It is intended for use on exhaust or supply air openings where a simple, reliable termination and a backdraft prevention function are required.
Advantages
The collar integrates a non-return valve that limits reverse airflow without requiring separate valve installation, reducing installation time and saving wall space. Its white finish ensures a neutral appearance that blends with typical interior and exterior wall surfaces. The product is compatible with standard Ø100 mm round ducts and is made for straightforward mechanical fastening to wall openings, providing a stable and durable termination point for ventilation runs.
Suitable for
Termination of Ø100 mm round ventilation ducts in residential buildings

Light-commercial ventilation where compact wall collars are required
Key specifications

Integrated non-return (backdraft) valve

How to use
Select a compatible Ø100 mm duct and prepare a wall opening sized to fit the collar. Insert the duct into the collar and secure the duct to the collar according to local installation practices, using appropriate clamps or sealants where necessary to ensure airtight connection. Fasten the collar to the wall using suitable screws or anchors for the wall material. Verify that the non-return valve moves freely and that the assembly provides the intended airflow direction and sealing.
Usage recommendations
Inspect the collar and non-return valve periodically for dust, debris, or damage and clean as required to maintain airflow and backflow protection. Ensure the collar is installed with correct orientation for intended exhaust or supply function and use appropriate fixings and sealants compatible with the wall surface and ducting material.
