SpiroFlex elbow DN 200 45° — SpiroFlex Kolano DN 200, 45°

SpiroFlex elbow DN 200 45° is a round duct fitting designed to change airflow direction by 45 degrees in ventilation and air distribution systems. Manufactured for compatibility with DN 200 circular ducts, this elbow provides a compact solution for rerouting air in HVAC installations, air handling units and industrial ventilation runs. The component is intended for use where a smooth directional transition is required without significant additional space.

Advantages

The elbow offers a compact 45° turn that minimizes footprint while maintaining consistent airflow through the duct system. Its round profile preserves cross-sectional area to reduce turbulence and pressure loss compared with abrupt or rectangular transitions. The fitting is compatible with standard DN 200 circular ducts, enabling straightforward integration into existing round duct networks. The design supports efficient installation and alignment in constrained or compact layouts.

Suitable for

• HVAC installations in commercial and residential buildings
• Connections to air handling units and fans
• Industrial ventilation runs and process extraction systems
• Retrofit projects where space is limited

Key specifications

• Nominal diameter: DN 200
• Bend angle: 45°
• Shape: round/elbow
• Application: ventilation and air distribution
• Compatibility: connects to standard DN 200 circular ducts

How to use

Position the elbow between two sections of DN 200 circular duct so the flange or joint faces align. Secure connections with appropriate clamps, seals or fastening methods for your duct system to ensure airtight joints. Ensure the elbow orientation provides the required 45° change in direction and check clearances to avoid interference with other components. After installation, inspect joints for leaks and perform any necessary sealing or insulation according to system requirements.

Usage recommendations

For optimal airflow and reduced pressure losses, maintain smooth internal surfaces and avoid sharp bends immediately upstream or downstream of the elbow. Use compatible sealing materials rated for the operating temperature and environment, and follow local ventilation standards when integrating the elbow into HVAC systems.
