Ventilation grille AWENTA TRU18K for 150 mm duct, model TRU18K, white

AWENTA TRU18K is a white ventilation grille designed for 150 mm duct connections. The grille provides a finished appearance for wall or ceiling-mounted ventilation outlets and inlets in residential and light-commercial settings. It is intended to cover and protect 150 mm circular duct terminations while allowing free airflow; the simple geometry fits common bathroom, kitchen and utility room ventilation runs where fi150 ducting is used.

Advantages

The AWENTA TRU18K grille offers a clean, neutral finish in white that integrates with typical interior surfaces. Its construction provides protection for duct edges and helps prevent direct access to the duct while maintaining airflow. The design supports straightforward installation and removal for inspection or maintenance of the connected ducting. Materials and finish are chosen to resist typical indoor humidity and provide a long service life in domestic ventilation applications.

Suitable for

• Covering and finishing 150 mm circular ventilation duct outlets and inlets
• Bathroom and kitchen exhaust or supply vents in residential properties
• Utility rooms, laundry rooms and light-commercial ventilation points using 150 mm ducts
• Applications requiring a simple, white grille to match interior finishes

When it may not be suitable

This grille is sized specifically for 150 mm (fi150) circular ducts and will not fit ducts of other diameters without adapters. It is a passive finishing component and does not include integrated dampers, filters, or fans; systems that require adjustable airflow control, filtration, or powered ventilation will need additional components. For exterior use or environments with aggressive chemicals or extreme weather exposure, select a grille specified for those conditions.

Key specifications

• Color: white
• Compatible duct diameter: 150 mm (circular)
• Typical mounting: wall or ceiling finish for duct termination
• Function: air inlet/outlet cover and protection
• Suitable environment: indoor residential and light-commercial spaces

How to use

Position the grille over the 150 mm duct termination so the duct aligns with the grille inlet. Secure the grille to the mounting surface using appropriate fasteners for the wall or ceiling material; ensure a tight, stable fit to avoid gaps around the duct edge. The grille can be removed for visual inspection or basic maintenance of the duct connection. If the system requires a filter, damper or fan, install those elements inside the duct run before fitting the grille.

What to consider before purchase

• Confirm the duct diameter is 150 mm to ensure correct fit
• Decide whether a grille-only solution is sufficient or if dampers/filters/fans are required
• Check mounting surface type to select correct fasteners and installation method
• Verify indoor suitability; choose a different product for outdoor or corrosive environments

Usage recommendations

For reliable operation, fit the AWENTA TRU18K after any internal ventilation components (filters, silencers, dampers) and inspect the duct connection periodically. Clean the grille surface with a damp cloth; avoid aggressive solvents. If airflow adjustment is needed, integrate an internal damper or control device within the duct system rather than modifying the grille.
