## Long description

AWENTA KO150-22 is a round duct connector with an integrated non-return valve, designed for Ø150 mm ventilation ducts. It provides a compact solution for connecting sections of circular ductwork while preventing reverse airflow. The unit is finished in white and intended for inline installation within HVAC air distribution and exhaust systems in residential and light-commercial settings.
Advantages
The connector combines a mechanical joint and a check valve in a single component, reducing the number of fittings required and simplifying installation. Its integrated non-return valve limits backflow and protects ventilation equipment from unwanted air movement. The white finish supports unobtrusive visual integration with common ductwork and terminal fittings. The product is suitable for use in standard Ø150 mm circular duct systems and is compatible with common installation methods for metal and rigid plastic ducts.
Suitable for
Connecting Ø150 mm round ventilation ducts
Preventing backflow in exhaust and supply lines
Inline installation in residential ventilation systems
Use in light-commercial air distribution and exhaust applications
Key specifications
Connector shape: round
Nominal diameter: 150 mm
Integrated function: non-return (check) valve
Finish: white
Intended installation: inline within duct runs
How to use
Install the AWENTA KO150-22 by inserting it between two matching Ø150 mm duct sections, ensuring secure mechanical connection according to duct material and fastening practice (clamps, screws, or sealants as applicable). Orient the non-return valve in the direction of the intended airflow so the valve opens during normal ventilation and closes to prevent reverse flow. Verify alignment and seal joints to avoid air leaks. Follow applicable local codes and standard HVAC installation procedures during mounting and commissioning.
Usage recommendations
Periodically inspect the valve for obstruction and proper movement, especially after commissioning and during routine maintenance. Ensure the connector is accessible for inspection and that surrounding ductwork maintains the same nominal diameter to preserve airflow characteristics.
