Ventilation exhaust grille airRoxy 02-306 brown with adjustable louver Ø120 mm

airRoxy 02-306 brown exhaust ventilation grille with adjustable louver and Ø120 mm compatibility is designed for wall or ceiling installation in residential and light commercial interiors. The unit directs airflow from internal spaces into an exhaust duct while helping to reduce backdrafts. Its compact round opening and adjustable blade allow alignment of airflow direction with connected Ø120 mm ventilation ducts, providing a practical solution for bathroom, kitchen and utility room exhaust systems.

Advantages

The grille features an adjustable louver that lets you direct airflow and fine-tune ventilation performance without replacing the unit. Its brown finish integrates with interior surfaces and fixtures where darker tones are preferred. Constructed for easy mounting, the grille fits standard Ø120 mm ducts and reduces unwanted inflow by working as a backdraft barrier. The compact design minimizes visual impact while maintaining sufficient airflow for typical domestic exhaust needs.

Suitable for

• Bathroom exhaust systems connected to Ø120 mm ducts
• Kitchen range hood or general kitchen ventilation
• Utility rooms, laundry areas and small service rooms
• Wall or ceiling installations in residential and small commercial premises

Key specifications

• Design: round grille with adjustable louver
• Compatibility: suitable for Ø120 mm ventilation ducts
• Finish: brown
• Mounting options: wall or ceiling
• Function: exhaust airflow direction and backdraft reduction

How to use

Mount the grille on a prepared wall or ceiling opening aligned with a Ø120 mm ventilation duct. Secure the grille with appropriate fasteners for the substrate and ensure a tight connection to the duct to prevent air leakage. Adjust the louver position to achieve the desired exhaust direction and to limit reverse airflow. Periodically inspect the grille and clean dust or debris from the louver and faceplate to maintain airflow efficiency.

Usage recommendations

For reliable ventilation performance, confirm that the exhaust fan and ducting are matched to the grille diameter and that ducts are free of obstructions. Use corrosion-resistant fasteners in humid environments and clean the grille at regular intervals to prevent airflow reduction. If noise or reduced flow occurs, inspect the louver position and duct connections before considering replacement.
