## Summary description

Round duct connector airRoxy 8324 with built-in non-return (check) valve, designed for Ø100 mm ventilation ducts.

## Long description

The airRoxy 8324 round duct connector with built-in non-return valve is designed for Ø100 mm ventilation ducts. This compact connector integrates a one-way check valve to prevent backflow and reduce unwanted drafts in supply or exhaust lines. The unit is suitable for wall or ceiling installations and can be used for new installations or retrofit projects where a compact valve-integrated connector is needed.
Advantages
The integrated non-return valve ensures unidirectional airflow without the need for a separate damper, simplifying installation and reducing the number of components. Its round Ø100 mm form factor provides compatibility with standard ducting and allows a neat fit in confined spaces. The connector’s simple mechanical design offers reliable operation with low maintenance requirements and helps maintain indoor air quality by preventing reverse air infiltration.
Suitable for
Residential supply or exhaust ventilation lines with Ø100 mm ducts
Commercial or light-industrial ventilation where compact one-way control is required
Wall or ceiling installations and retrofit projects in apartments or small offices
Systems requiring prevention of backflow and reduction of drafts
Key specifications
Connector shape: round
Nominal duct diameter: 100 mm
Integrated function: non-return (check) valve for one-way airflow
Typical installation locations: wall or ceiling inline connection
Application: suitable for supply and exhaust ventilation
Design features: compact profile for retrofit and space-limited installations
How to use
Install the round connector inline with Ø100 mm ductwork, ensuring the valve is oriented so the arrow or labeled flow direction corresponds to the intended airflow. Secure the connector to duct ends using appropriate clamps or sealant to maintain an airtight joint. For wall or ceiling penetration, mount the connector in the prepared opening and connect to the internal duct run. After installation, verify that the valve opens under normal airflow and closes when the system is off to prevent backflow.
Usage recommendations
Check for correct orientation before final sealing, and inspect the valve periodically for dust accumulation or obstruction. For installations in areas with heavy particulate load, consider placing a filter or access point for cleaning. Use compatible Ø100 mm duct fittings and fasteners to ensure a secure, low-leak connection.
