Ventilation grille with louvre AWENTA T78 140x140 mm Ø125 mm white

The AWENTA T78 ventilation grille with louvre is a wall or duct-mounted air outlet designed for Ø125 mm connections and a 140×140 mm faceplate. Finished in white, the grille incorporates an adjustable louvre that lets you direct discharged air where needed. The product is intended for use in residential and light commercial ventilation systems to control air discharge and airflow direction while providing a neat visible finish.

Advantages

The integrated adjustable louvre allows precise redirection of airflow without additional fittings. The compact 140×140 mm faceplate provides a discreet finish for walls or duct terminations while covering the connection to Ø125 mm ducts. A white surface finish offers a neutral appearance that matches most interior décors and is easy to clean. The grille is lightweight and simple to install, suitable for retrofit or new installations where a small, directional outlet is required.

Suitable for

• Residential ventilation systems in bathrooms, kitchens, and utility rooms
• Light commercial premises such as small offices, retail backrooms, and service areas
• Duct terminations and wall outlets for Ø125 mm ventilation ducts
• Retrofit projects where an adjustable airflow direction is needed

When it may not be suitable

This grille is intended for systems using Ø125 mm ducts and may not fit larger or smaller duct sizes without an adapter. It is designed for moderate airflow and typical residential or light commercial use; applications requiring high-volume industrial air handling or heavy particulate loading may require a more robust or specialised grille or filter arrangement.

Key specifications

• Faceplate dimensions: 140 × 140 mm
• Connection size: designed for Ø125 mm duct connection
• Finish: white
• Airflow control: adjustable louvre for directional control
• Mounting: wall or duct-mounted outlet

How to use

Position the grille over the Ø125 mm duct termination or wall opening and secure it according to the mounting method appropriate for the surface (screws or snap-fit where applicable). Adjust the louvre orientation to direct airflow to the desired area; fine adjustments can be made while the ventilation system is operating to observe the effect on airflow distribution. Periodically clean the visible faceplate and louvre with a damp cloth to remove dust; ensure the ventilation system is switched off before performing maintenance.

What to consider before purchase

• Confirm that your duct or outlet is Ø125 mm to ensure proper fit
• Check available wall or duct mounting space for a 140 × 140 mm faceplate
• Consider whether adjustable directional louvre is sufficient for your airflow needs or if additional dampers/controls are required

Usage recommendations

For consistent performance, combine the grille with correctly sized ducting and maintain regular cleaning intervals. When installing in wet areas such as bathrooms, ensure the surrounding installation meets local building and ventilation regulations to prevent moisture-related issues.
