## Long description

AWENTA KO150-21 is a round duct connector for Ø150 mm ventilation ducts finished in white. Designed to join circular duct sections, this connector maintains airflow continuity in HVAC systems and provides a neat, low-profile junction point. It is suitable for residential and light commercial ventilation where reliable mechanical connection and simple installation are required.
Advantages
The connector delivers a stable, centered connection between matching Ø150 mm round ducts and reduces air leakage at joint points when installed correctly. Its white finish offers a discreet appearance in visible installations and simplifies alignment of duct runs. Manufactured for compatibility with standard Ø150 mm round ducts, the component facilitates quick assembly and repair without the need for specialized tools.
Suitable for
Connecting two sections of Ø150 mm round ventilation duct

Shape: round connector for circular ducts
Finish: white
Compatibility: designed for standard Ø150 mm ventilation ducts

How to use
Ensure both duct ends to be joined are clean, free of burrs and aligned coaxially. Slide each duct end onto the connector until the ducts meet at the connector's center, then secure the joint with appropriate duct clamps, tape or silicone sealant according to local practice and codes. Verify the connection is tightly fitted and check for leaks after system start-up. For installations in visible areas, position the white finish outward to match surrounding components.
Usage recommendations
For best performance, use the connector with matching Ø150 mm round ducts and apply a suitable sealing method (mechanical clamp or HVAC tape and sealant) to minimize air leakage. Avoid excessive bending or stress on joined duct sections and follow local ventilation codes for fastening and support distances.
