SpiroFlex elbow 90° DN 160 pipe fitting by SpiroFlex

SpiroFlex elbow 90° DN 160 pipe fitting by SpiroFlex is a 90-degree circular duct elbow designed for ventilation and air-conditioning systems. It provides a compact right-angle change of airflow direction for round ducts with nominal diameter DN 160. The fitting is intended for use where a clean, consistent transition is required between two sections of DN 160 ducting and where space constraints require a tight 90° bend.

Advantages

The elbow is manufactured to ensure a smooth airflow transition with minimal leakage and reliable mechanical connection to DN 160 round ducts. Its geometry reduces turbulence at the turn and supports efficient airflow in HVAC routing. The fitting is suitable for confined installations and allows straightforward integration into standard round duct systems without the need for complex adapters.

Suitable for

• Changing airflow direction by 90° in ventilation and air-conditioning networks
• Connecting sections of DN 160 round ductwork
• Branch transitions and compact routing in limited-space installations

Key specifications

• Nominal diameter: DN 160 for circular duct connection
• Angle: 90° right-angle elbow
• Application: ventilation and air-conditioning duct systems
• Compatibility: designed for standard DN 160 round ducts and fittings
• Function: provides a sealed mechanical turn with reduced turbulence

How to use

Fit the SpiroFlex 90° elbow between two DN 160 round duct sections, ensuring correct orientation for the desired change of direction. Use appropriate sealing methods and fasteners compatible with the duct material to secure connections and prevent air leakage. Verify alignment and support the duct run to avoid stress on the elbow and adjacent joints.

Usage recommendations

For best performance, inspect mating duct ends for burrs or damage before assembly, apply suitable duct sealing (such as silicone sealant or approved tape) at connections, and provide mechanical support near the elbow to prevent sagging. Consider acoustic lining or gradual transition fittings if noise or pressure loss is a concern in the system.
