Ventilation exhaust grille AWENTA KO150-30BR for 150 mm round duct, brown

AWENTA KO150-30BR is a brown exhaust ventilation grille designed for 150 mm (Ø150) round duct systems. It serves as an outlet cover that completes the ventilation run, allowing exhaust air to leave the duct while preventing large debris from entering the ventilation network. The grille is intended for residential and light-commercial installations where a compact, round terminal is required and where brown finish is preferred for aesthetic matching.

Advantages

The grille offers a compact, low-profile design that fits standard 150 mm circular ducts and delivers a finished appearance at the duct terminus. Its construction facilitates unobstructed airflow and provides basic protection against insects and larger particles. The brown color provides a discreet visual integration with interiors or façades that require darker trim. Installation is straightforward and compatible with common round ductwork.

Suitable for

• Exhaust terminals for bathrooms and kitchens
• Ventilation outlets in residential apartments and houses
• Light-commercial premises such as small offices or retail spaces
• Replacement of existing 150 mm round grille terminals

Key specifications

• Designed for 150 mm (Ø150) round duct connection
• Exhaust airflow application
• Brown finish for visual integration
• Compact, low-profile terminal design
• Protects duct opening from debris and larger particles

How to use

Align the grille with the end of the 150 mm circular duct and insert or secure it according to the duct system and mounting method in use. Ensure the grille sits flush and is fastened so that the airflow path remains unobstructed. Verify that the surrounding sealing and any used fasteners do not restrict the grille opening. After installation, run the ventilation system and check for proper exhaust flow and any unwanted vibrations or rattling; tighten fasteners if required.

Usage recommendations

For reliable performance, periodically inspect the grille and clean away accumulated dust or debris. In environments with high particulate load, consider more frequent checks. When replacing an existing terminal, confirm the duct diameter is 150 mm to ensure compatibility. Use suitable fasteners and avoid over-tightening to prevent deformation of the grille.
