## Summary description

Vaillant 90° elbow with 80 mm diameter (model 300818) is a pipe fitting designed for flue and ventilation systems. This right-angle connector provides a compact directional change in ducts with an 80 mm bore. Suitable for use in installations requiring a 90-degree turn of exhaust or ventilation airflow; compatible with systems using 80 mm components.

## Long description

The Vaillant 90° Elbow with 80 mm diameter is a right-angle duct fitting designed for flue and ventilation systems. Engineered to provide a compact directional change, this 90-degree connector adapts airflow paths in installations that use 80 mm components. The fitting is suitable for exhaust and ventilation ducts where space constraints or routing needs require a neat, reliable bend without changing internal diameter.
Advantages
This 90° elbow maintains a consistent 80 mm internal bore to reduce turbulence and preserve airflow performance in short directional transitions. Its compact footprint allows installation in confined spaces and simplifies routing of duct runs. The component is manufactured to fit standard 80 mm ventilation and flue systems, ensuring compatibility and ease of assembly. The design minimizes the need for additional adapters when integrating into existing ductwork.
Suitable for
Redirecting exhaust gases in flue systems with an 80 mm bore
Changing direction of ventilation ducts in residential and light-commercial installations
Routing ducts in confined or low-clearance spaces
Connecting components within an 80 mm ventilation/flue system
Key specifications
Inner diameter: 80 mm
Angle: 90 degrees (right angle)
Function: duct elbow for flue and ventilation airflows
Compatibility: designed for systems using 80 mm components
Form factor: compact right-angle connector to change airflow direction
How to use
Position the elbow to align with the incoming and outgoing duct segments, ensuring a continuous 80 mm bore throughout the junction. Secure the connections according to the installation requirements of the ventilation or flue system, using appropriate clamps, seals or fastening methods compatible with the duct material. Confirm the elbow orientation provides the intended airflow direction and check for any obstructions. After assembly, perform a visual inspection and pressure or flow test if required by local installation standards to verify airtightness and correct operation.
Usage recommendations
Use this elbow in systems designed for 80 mm components and follow applicable regulations for flue and ventilation installations. Avoid sharp additional bends immediately adjacent to the elbow to limit airflow losses, and ensure regular inspection and maintenance access. If flue gases are present, verify material compatibility and clearances as required by local codes and the appliance manufacturer.
