Ventilation grille DOSPEL BELLA 100 is a compact wall or ceiling outlet designed for connection to 100 mm (Ø100) ventilation ducts. The grille provides a clean finished appearance for air extraction or supply in residential and light-commercial ventilation systems. It is intended for use where a standard 100 mm duct interface is required, offering a simple means of terminating a duct run and directing airflow through bathrooms, kitchens or utility rooms.

The visible faceplate gives a neat aesthetic finish and is easy to clean. Designed for straightforward installation, the grille is compatible with common mounting methods in walls and ceilings and is resistant to the typical moisture and temperature conditions found in wet rooms.

How to use

Prepare the installation opening to match a 100 mm duct diameter and position the grille so the circular inlet aligns with the duct end. Secure the grille to the wall or ceiling using appropriate fasteners for the surface material, ensuring a tight fit to minimise gaps. Connect the duct to the grille inlet and, if required, seal the joint with suitable tape or sealant to prevent air leakage. After installation, check airflow direction and grille alignment and clean the faceplate as needed during routine maintenance.

Usage recommendations

Use the grille with standard 100 mm ventilation ducts and compatible fans or passive ventilation lines. For installations in damp areas, verify compatibility of surrounding materials and seals. Clean the faceplate periodically with a soft cloth and mild detergent; avoid abrasive cleaners. When in doubt about mounting in non-standard constructions, consult a qualified installer to ensure airtight connections and secure fixing.
