## Summary description

SpiroFlex turbo elbow double-walled (n) 90° 80/125 is a ventilation duct component designed for change of direction in round ducts. The product features a concentric 80/125 mm size ratio, double-walled construction for improved thermal and acoustic performance, and a 90-degree bend suitable for HVAC systems, exhaust and supply duct routing in residential or commercial installations.

## Long description

SpiroFlex turbo elbow double-walled (n) 90° 80/125 is a round duct fitting engineered to change airflow direction in ventilation systems. The unit has a concentric 80/125 mm diameter ratio and a double-walled construction that improves thermal insulation and reduces noise transmission through ductwork. Its 90° bend is intended for use in HVAC supply and exhaust lines where a compact directional change is required without compromising airflow efficiency.
Advantages
The double-walled design provides enhanced thermal separation between the inner and outer shells, helping to limit heat transfer and condensation. Acoustic damping from the cavity between walls reduces airborne noise compared with single-wall elbows. The concentric 80/125 configuration ensures a smooth transition between different duct diameters while maintaining laminar flow characteristics. Manufactured for standard round duct systems, the turbo elbow is built to integrate with common duct connections and minimize installation adjustments.
Suitable for
Residential and commercial HVAC supply and exhaust duct routing
Ventilation systems requiring a 90° change of direction in round ducts
Applications where improved thermal insulation and noise reduction are needed
Retrofit projects joining ducts of 80 mm to 125 mm diameters
Key specifications
Shape: 90° elbow for round ducts
Construction: double-walled concentric design
Diameter ratio: inner and outer concentric sizes 80 mm and 125 mm
Material characteristics: corrosion-resistant metal shells with internal cavity for insulation and acoustic damping
Application: compatible with supply and exhaust ventilation in residential and commercial settings
How to use
Position the turbo elbow at the required change of direction and align the concentric ends with the corresponding duct sections. Secure connections using appropriate clamps or sealing methods recommended for round metal ducts to ensure airtight joints. If additional thermal insulation is required for the installation environment, apply external insulation around the outer wall without compressing the cavity between walls. Verify that the elbow orientation does not impede access for maintenance and that clearances meet local ventilation codes.
Usage recommendations
Install in line with the airflow direction indicated by system design, avoid sharp kinks in adjacent duct runs, and inspect seals after initial operation. For noise-sensitive environments, consider combining the double-walled elbow with flexible connectors or additional acoustic lining upstream or downstream. Follow local building and ventilation standards for support spacing and fire-safety requirements.
