Ventilation grille airRoxy 02-325 round closable universal, Ø (unspecified) model 02-325

The airRoxy round closable universal ventilation grille model 02-325 is a mechanical air outlet/inlet cover designed to provide adjustable airflow control in ducted ventilation systems. Intended for wall or ceiling installation, this round grille features a closable shutter mechanism that enables regulation of ventilation and helps prevent backdrafts when the ventilation system is not running. The product is suitable for domestic and commercial interiors where a round universal fitting is required.

Advantages

The closable shutter allows precise manual regulation of airflow and effective prevention of unwanted air infiltration. Its universal round form factor simplifies installation in standard round ducts or openings, while the mechanical design ensures long-term reliability without electrical supply. The grille is compatible with common wall and ceiling mounting situations and is suitable for use in both residential and commercial environments where simple, robust ventilation control is needed.

Suitable for

• Residential rooms requiring adjustable ventilation (bathrooms, kitchens, utility rooms)
• Commercial interiors with ducted ventilation systems (offices, shops, service premises)
• Wall or ceiling installations where a round, closable grille is required
• Applications where a manual, maintenance-free shutter is preferred to prevent backdrafts

Key specifications

• Design: round ventilation grille with closable shutter
• Function: manual airflow regulation and backdraft prevention
• Installation: suitable for wall or ceiling mounting in ducted ventilation systems
• Application: compatible with standard round openings and ducts (universal fitting)
• Use cases: designed for both domestic and commercial ventilation needs

How to use

Install the grille into a matching round opening or duct using appropriate fasteners and sealants for the wall or ceiling material. Adjust the shutter manually to increase or reduce airflow as required; fully close the shutter to prevent backdrafts when ventilation is not needed. Periodically inspect the grille and shutter for dust buildup or obstructions and clean with a soft brush or damp cloth to maintain free movement and airflow efficiency.

Usage recommendations

For reliable performance, ensure the grille diameter matches the existing round duct or opening and that mounting is airtight to avoid unintended leaks. Regular visual inspection and light cleaning will keep the shutter operating smoothly; avoid using aggressive chemicals or abrasive tools when cleaning. If used in wet or high-humidity environments, verify compatibility with local building standards and consider additional protective measures if corrosion resistance is required.
