Dospel Kolanko łącznikowe D/KŁZ 104/110x55 007-0223 duct elbow connector 104/110×55

Dospel Kolanko łącznikowe D/KŁZ 104/110x55 (model 007-0223) is a metal duct elbow connector designed for ventilation and HVAC installations. The component connects round ducts with nominal diameters of 104 mm and 110 mm and provides a 55 mm offset to change the airflow direction or adapt mismatched duct sizes. It is intended for use in residential and commercial ventilation systems where a compact, robust connection is required to reroute air or bridge slight diameter differences.

Advantages

The metal construction ensures mechanical strength and durable performance in standard ventilation conditions. The elbow connector's stepped diameters accommodate two common round duct sizes without the need for additional adapters, simplifying installation. Its compact offset design saves space in tight mounting areas and allows for controlled directional change of airflow. The product is compatible with conventional round metal ducts and is suitable for integration into existing HVAC assemblies.

Suitable for

• Connecting round ventilation ducts with diameters close to 104 mm and 110 mm
• Changing airflow direction in residential ventilation systems
• Adaptation or repair of commercial HVAC duct runs with limited space
• Bridging small diameter mismatches without custom fabrication

Key specifications

• Material: metal construction suitable for standard ventilation use
• Nominal diameters: connects ducts around 104 mm and 110 mm
• Offset length: 55 mm to provide directional change or spacing
• Shape: elbow connector allowing a compact angular transition
• Compatibility: intended for round metal ventilation ducts and HVAC systems

How to use

Fit the larger end of the elbow connector onto the corresponding round duct and the smaller end onto the matching duct section, ensuring a snug overlap. Secure connections with appropriate clamps, tape, or rivets depending on the duct material and site requirements. Align the offset to achieve the required directional change and verify that the joined ducts maintain a continuous airflow path without sharp obstructions. After installation, check for air leaks and tighten fastenings as needed.

Usage recommendations

Use corrosion-resistant fasteners in humid or corrosive environments and inspect joints periodically for tightness and integrity. For installations subject to high airflow velocities or pressure differences, ensure connections are reinforced and sealed to prevent leakage. If precise airflow balancing is required, consider measuring performance after installation and adjust sealing or support as necessary.
