## Summary description

ALNOR TWIN BEND ANGLE 45 model YSVL-45-160-160 is a ventilation duct fitting featuring a 45° twin bend design for redirecting airflow in ductwork. Intended for use with Ø160 mm ducts, this metal fitting provides a compact change of direction for HVAC systems, exhausts and air distribution networks, helping route ducts around obstacles and optimize airflow paths.

## Long description

ALNOR TWIN BEND ANGLE 45 YSVL-45-160-160 is a metal ventilation fitting designed to create a compact 45° twin bend in round duct systems with a nominal diameter of 160 mm. The fitting redirects airflow smoothly while occupying minimal space, making it suitable for HVAC systems, exhaust lines and air distribution networks where a controlled change of direction is required. Constructed for installation in metal ductwork, the component helps route ducts around obstacles and maintain efficient air movement.
Advantages
The 45° twin bend geometry reduces flow separation and minimizes pressure loss compared with abrupt directional changes, supporting better system efficiency. Its metal construction offers durability and dimensional stability under typical ventilation conditions. The compact profile allows installation in confined spaces and simplifies duct routing without extensive additional components. The fitting is compatible with standard Ø160 mm round ducts and can be integrated into new installations or retrofit projects.
Suitable for
 HVAC ventilation branches in residential and commercial buildings
 Exhaust and supply air ducts requiring a 45° change of direction
 Projects with limited installation space where a compact bend is needed
 Retrofit work to re-route ductwork around structural obstacles
Key specifications
 Nominal duct diameter: 160 mm
 Bend angle: 45° twin bend configuration
 Material: metal (suitable for standard ventilation ductwork)
 Connection type: for round ducts with matching Ø160 mm ends
 Application: air distribution, supply or exhaust ventilation
How to use
Install the twin bend fitting into the ventilation run by inserting the matching Ø160 mm duct ends into the fitting connections and secure with appropriate clamps, seals or rivets according to national installation standards. Ensure alignment to achieve the intended 45° directional change and check that joint sealing prevents air leakage. Support the ductwork as required to avoid strain on the fitting and verify that airflow direction and clearance are correct before commissioning the system.
Usage recommendations
Ensure sealing at all joints and provide mechanical support to reduce vibration and stress. When combining with other fittings, allow for smooth transitions and maintain consistent internal diameter to minimize pressure losses. Follow local HVAC codes and manufacturer guidance for fastening and corrosion protection.
