Ventilation grille AWENTA T86BR for duct Ø125 mm, brown

AWENTA T86BR is a brown ventilation grille designed for circular duct systems with a nominal diameter of 125 mm. Intended for use as an inlet or outlet on round ventilation ducts, the grille provides a finished appearance to the duct opening, protects the interior of the duct from large debris and helps direct airflow. Its compact design makes it suitable for installations where a discreet, color-matched terminal is required for extraction or supply air.

Advantages

The grille offers a simple and compact solution for terminating Ø125 mm circular ducts while maintaining a uniform look in brown finishes. It provides physical protection for the duct opening and helps guide air smoothly into or out of the system. Constructed for straightforward mounting, the model is suitable for both residential and light commercial ventilation applications where space and appearance matter.

Suitable for

• Terminating round ventilation ducts with a nominal diameter of 125 mm
• Bathroom or kitchen extraction terminals in residential properties
• Supply or exhaust points in small commercial or utility rooms
• Situations where a brown-coloured grille is preferred to match interior finishes

When it may not be suitable

This grille is designed specifically for circular ducts of approximately 125 mm diameter and may not fit rectangular ducts or ducts of substantially different diameters. It is a terminal grille intended for air guidance and protection; it does not include sound attenuation, filtration media, or motorized components. For systems requiring integrated backdraft dampers or specialized filtration, a different product should be selected.

Key specifications

• Intended duct type: circular/round
• Nominal duct diameter: 125 mm (Ø125)
• Colour: brown
• Function: air inlet/outlet terminal and opening protection
• Typical mounting: end-of-duct surface or recessed mounting for round duct terminals

How to use

Install the grille at the end of a Ø125 mm round ventilation duct ensuring a secure fit and alignment with the duct axis. If necessary, trim or adapt the duct end so the grille seats evenly. Fix the grille using appropriate screws or clips for the mounting surface and material, ensuring a stable attachment and an even seal around the duct to minimise air leakage. Use the grille for either supply or exhaust airflow as part of a balanced ventilation system, and inspect periodically for dust accumulation or damage.

What to consider before purchase

• Verify that the duct is circular and has a nominal diameter of 125 mm.
• Confirm that the brown colour is appropriate for the installation location and visual requirements.
• Check whether additional components such as dampers, filters or silencers are needed for your ventilation design.
• Ensure the chosen mounting method and fixing hardware match the surface material (plasterboard, masonry, metal, etc.).

Usage recommendations

For optimal performance, keep the grille free of accumulated dust and debris by inspecting and cleaning it periodically. If the ventilation system requires humidity or odour control, consider pairing the grille with appropriate in-line filtration or a damper installed within the ductwork rather than relying on the terminal alone.
