## Summary description

airRoxy ventilation reducer (model 7709) is a duct connector that adapts a rectangular section 110x55 mm to a round duct with 100 mm diameter. Designed for air distribution and extraction systems, it enables transition between differing duct cross-sections, ensuring airflow continuity in residential or light-commercial ventilation installations.

## Long description

airRoxy ventilation reducer 110x55 to Ø100 air duct connector model 7709 is a metal transition piece that converts a rectangular duct section of 110 x 55 mm into a round duct with 100 mm internal diameter. It is intended for installation in ventilation and air extraction systems where a change of cross-section is required to connect rectangular spigots, grilles or plenums to circular ducts. The component provides a continuous airflow path while maintaining a compact footprint suitable for residential and light-commercial ventilation layouts.
Advantages
This ventilation reducer offers a simple and reliable mechanical transition between rectangular and circular ducting, limiting turbulence at the change of section. The compact geometry reduces the amount of space required for the connection and facilitates installation in tight service voids. Constructed to match standard duct dimensions, it supports compatibility with common 100 mm circular ductwork and 110 x 55 mm rectangular profiles used in domestic ventilation. The stable connection helps preserve airflow performance and reduces the need for custom fabrication.
Suitable for
 Connecting rectangular 110 x 55 mm spigots or ventilation outlets to Ø100 mm circular ducts
 Air distribution and extraction points in bathrooms, kitchens and utility rooms
 Retrofitting or modifying existing ventilation runs where section change is needed
Key specifications
 Rectangular inlet size: 110 x 55 mm
 Round outlet diameter: 100 mm (internal)
 Type: duct reducer / transition connector
 Intended use: ventilation air distribution and extraction
 Application environment: residential and light-commercial installations
How to use
Fit the rectangular end to the corresponding 110 x 55 mm duct or spigot ensuring a snug mechanical engagement, then connect the Ø100 mm circular end to the round duct section. Secure both ends with appropriate clamps, screws or sealing tape as required by the installation practice to prevent air leakage. Ensure the reducer is oriented to preserve the intended airflow direction and check that adjoining ducts are supported to avoid strain on the connection.
Usage recommendations
Verify compatibility with the existing duct profile and measure internal diameters before installation. Use corrosion-resistant clamps or suitable sealing materials in wet or humid environments, and perform a visual check for air leaks after the system is commissioned.
