## Long description

AWENTA round duct connector with non-return valve KO100-22 is a 100 mm white ventilation fitting designed to join circular ducts while preventing reverse airflow. The integrated check valve maintains unidirectional airflow, limiting backdrafts and reducing infiltration from adjacent spaces. The connector is suitable for residential and light commercial systems and is intended for use in exhaust, supply and recirculation ductwork for bathrooms, kitchens and utility rooms.
Advantages
The product combines a standard circular duct connection with a built-in non-return valve to ensure air moves in the intended direction. Its 100 mm diameter matches common ventilation duct sizes, enabling quick installation and compatibility with rigid and flexible ducts. The white finish provides a neutral appearance for visible installations and helps resist corrosion in typical indoor environments. The check valve reduces the risk of odour transfer and unintended draughts without adding complex components to the system.
Suitable for
Bathroom exhaust ducts
Kitchen ventilation and extractor systems
Supply and recirculation ducts in utility rooms
Small residential and light commercial ventilation installations
Key specifications
Connector shape: round
Integrated non-return (check) valve
Nominal diameter: 100 mm
Colour: white
Material: durable indoor-grade plastic
Suitable for rigid and flexible circular ducts
How to use
Position the round connector between two duct sections so that the airflow direction aligns with the orientation of the built-in non-return valve. Secure each duct end to the connector using appropriate clamps or sealing tape to ensure an airtight joint. Verify the valve moves freely and is not obstructed by installation debris. After installation, run the ventilation system and check for correct airflow direction and any leaks around joints.
Usage recommendations
Install the connector in an accessible location for inspection and maintenance. Use suitable clamps or duct sealant to achieve airtight connections, and avoid placing the valve where condensate or heavy debris may accumulate. Periodically inspect the check valve for smooth operation and clear any dust or lint that could impede movement.
