Duct Elbow AWENTA KO150-23 for round ventilation ducts Ø150 mm, 90°

AWENTA KO150-23 is a 90° duct elbow for round ventilation ducts with a nominal diameter of 150 mm. The component is designed to connect two sections of circular ducting and redirect airflow without reducing the cross-sectional area. It is intended for use in HVAC and ventilation systems where a compact right-angle turn is required and fits standard Ø150 mm round ducts.

Advantages

The elbow provides a smooth change of direction while maintaining duct diameter, which preserves airflow capacity and minimizes pressure loss compared with abrupt or improvised turns. Its circular cross-section ensures compatibility with standard Ø150 mm round ducts and simplifies assembly. The component is suitable for confined spaces where a compact 90° turn is necessary and is designed for reliable, long-term operation in residential and commercial ventilation installations.

Suitable for

• Redirecting airflow in residential ventilation systems
• Connections in commercial HVAC ductwork with Ø150 mm circular ducts
• Installing compact right-angle turns in utility rooms, attics, or shafts
• Retrofit and repair work on existing round duct installations

Key specifications

• Nominal diameter: 150 mm
• Angle: 90° elbow
• Shape: circular / round duct fitting
• Function: airflow redirection without reducing cross-sectional area
• Compatible with standard Ø150 mm round duct systems

How to use

Position the AWENTA KO150-23 elbow between two sections of Ø150 mm round duct so that the ends align concentrically. Secure the connections according to the duct system’s assembly method (clamps, sheet-metal screws, or rivets) and ensure the joint is sealed where required with appropriate duct sealant or tape to prevent leakage. Check that the elbow is oriented for the required airflow direction and that adjacent duct supports prevent undue stress on the joint.

Usage recommendations

For optimal performance, avoid sharp kinks or additional bends immediately upstream or downstream of the 90° elbow. Where noise or pressure loss is critical, consider using gradual bends or sound-damping measures in combination with this elbow. Regularly inspect joints and seals for leakage and service access to clean or remove accumulated debris.
