Ventilation grille AWENTA TRU2BR 150x150 mm brown, fixed louver TUS

AWENTA TRU2BR 150x150 mm brown fixed louver ventilation grille (TUS) is designed for wall or duct installation to enable air exchange while preventing ingress of debris. The grille fits standard 150x150 mm openings and is intended for use in residential and light commercial ventilation systems where a compact, fixed-louver solution is required. The brown finish provides a discreet appearance that blends with interior or exterior surfaces.

Advantages

The fixed louver configuration offers reliable airflow direction and simple construction with no moving parts, reducing maintenance needs. The compact 150x150 mm size makes the grille suitable for standard duct or wall apertures, and the brown color supports visual integration with a range of finishes. Its straightforward design allows for quick mounting and periodic cleaning to maintain airflow efficiency.

Suitable for

• Residential ventilation in bathrooms, kitchens, utility rooms
• Light commercial spaces such as small offices and service rooms
• Wall or duct terminations with standard 150x150 mm openings
• Applications requiring a fixed-louver grille to limit ingress of debris

When it may not be suitable

This fixed-louver grille does not provide adjustable airflow control and is not intended for applications that require variable dampers or integrated insect screens unless an additional accessory is fitted. It may not be appropriate for high-capacity industrial ventilation where larger sizes, motorized control, or specialized filtration are required.

Key specifications

• Type: fixed louver ventilation grille (TUS)
• Material: durable corrosion-resistant material suitable for ventilation use
• Nominal size: 150 x 150 mm (face dimensions for standard duct or wall openings)
• Finish: brown
• Mounting: designed for wall or duct installation with visible flange for fastening
• Maintenance: removable for cleaning and dust removal

How to use

Measure and prepare a standard 150x150 mm opening in the wall or duct. Position the grille so the flange sits flush against the mounting surface, then secure it with appropriate screws through the pre-drilled holes or mounting points. Ensure the louvres are oriented correctly for intended airflow direction. Periodically remove the grille and clean dust or debris using a soft brush or damp cloth to maintain unobstructed airflow; allow the grille to dry fully before refitting.

What to consider before purchase

• Confirm the duct or wall opening matches the grille's 150 x 150 mm nominal face size.
• Decide whether fixed louvres meet your need for airflow control versus adjustable dampers.
• Check compatibility with local ventilation system layout and mounting depth.
• Consider whether additional insect mesh or filters are needed for your location.

Usage recommendations

For reliable performance, install the grille at the termination point of the duct or wall opening with the louvres oriented away from prevailing outdoor contamination. Regularly inspect and clean the grille to prevent dust buildup; in environments with heavy particulate matter, add a pre-filter or insect screen upstream.
