AWENTA duct elbow 90° connector KP120-23 for rectangular 60×120 mm to round Ø100 mm

AWENTA KP120-23 is a 90° duct elbow connector engineered to link a rectangular duct section 60×120 mm with a round duct of Ø100 mm. Intended for ventilation and air extraction systems, this right-angle transition piece enables conversion between rectangular and circular profiles while maintaining airflow direction and allowing installation in constrained spaces. The connector is compatible with common HVAC ducts and is used where a compact change of cross-section is required.

Advantages

The 90° design provides a reliable angular transition without the need for multiple fittings, reducing potential leakage points and simplifying installation. Constructed to fit standard rectangular 60×120 mm and round Ø100 mm ducts, the connector ensures a snug mechanical junction and consistent airflow. Its compact form factor helps utilize limited installation space and makes it suitable for retrofits and new ductwork where profile conversion is necessary.

Suitable for

• Ventilation systems in residential and commercial buildings
• Kitchen and bathroom extraction ducts
• HVAC installations requiring a transition from rectangular 60×120 mm to round Ø100 mm
• Retrofit projects where space constraints prevent using longer transition sections

Key specifications

• Transition type: 90° elbow from rectangular to round
• Rectangular connection dimensions: 60 × 120 mm
• Round connection diameter: Ø100 mm
• Application: ventilation and air extraction ducting
• Mounting orientation: right-angle installation

How to use

Position the rectangular end of the elbow onto the 60×120 mm duct section, ensuring alignment and a flush fit. Attach the round end to the Ø100 mm round duct, verifying that both connections are secure and properly seated. Use appropriate HVAC sealant, tape, or clamps where required to ensure airtight joints according to local installation standards. Check that the elbow does not obstruct internal airflow and that surrounding supports prevent undue stress on the connections.

Usage recommendations

For best results, inspect mating duct ends for burrs or uneven edges before installation, and apply sealing material to prevent air leakage. Avoid sharp bends in adjacent ducting that could increase resistance; where possible maintain smooth transitions upstream and downstream of the elbow.
