## Long description

AWENTA KO125-22 is a round duct connector with an integrated backdraft damper designed for Ø125 mm ventilation ducts. Finished in white, it connects circular duct sections while preventing reverse airflow. The unit is intended for use in residential and light commercial ventilation systems where maintaining correct airflow direction and reducing drafts in ductwork are required.
Advantages
The integrated non-return damper prevents backflow and reduces the risk of unwanted drafts, while the circular connector design ensures a smooth transition between Ø125 mm duct sections. The white finish offers a neutral appearance suitable for exposed installations and service spaces. The product is compact and simple to fit into existing duct runs, supporting reliable airflow control without additional components.
Suitable for
 Connecting Ø125 mm circular ventilation ducts
 Preventing reverse airflow in residential ventilation systems
 Use in light commercial ventilation and service spaces
 Retrofit installations where a compact non-return solution is needed
Key specifications
 Connector diameter: 125 mm (suitable for Ø125 mm ducts)
 Integrated backdraft (non-return) damper to control airflow direction
 Finish: white for neutral appearance
 Design: circular connector compatible with round duct sections
How to use
Insert the connector between two Ø125 mm circular duct sections and secure each end according to the ducting system's clamping or fastening method (e.g., clamps, screws, or duct tape). Ensure the damper is oriented so it allows airflow in the intended direction and closes against reverse flow. Verify that ducts are aligned to avoid obstructing damper operation and perform a visual check to confirm the damper moves freely before final sealing.
Usage recommendations
Install the connector in accessible locations to allow inspection and maintenance of the damper. Avoid installing where heavy condensation or excessive dust accumulation may impede damper movement; where such conditions exist, schedule periodic cleaning. Ensure compatibility with other Ø125 mm components and follow local ventilation installation standards for secure fastening and sealing.
