Ventilation wall collar AWENTA KO150-27 round Ø150 mm white

AWENTA KO150-27 round Ø150 mm white is a wall-mounted ventilation collar designed to connect circular ducting to exterior or interior walls. It provides a sealed, low-profile transition between the duct and the wall opening, suitable for residential and light-commercial ventilation systems. The unit is intended for use with rangehood exhausts, bathroom fans, and general air extraction where a neat wall termination and reliable connection are required.

Advantages

The collar offers a secure, circular connection for 150 mm ductwork, made to maintain airtightness at the wall penetration and reduce air leakage. Its white finish enables a discreet appearance on most wall surfaces. The simple, compact design supports straightforward installation and reduces the need for additional adapters when connecting standard Ø150 mm ducts. Materials are chosen for indoor and sheltered exterior use where corrosion resistance and dimensional stability are important.

Suitable for

• Connecting rangehood exhaust ducts to an external wall
• Bathroom and kitchen extractor fan wall terminations
• Residential and light-commercial ventilation systems with Ø150 mm ducting

Key specifications

• Nominal diameter: 150 mm
• Shape: round
• Mounting type: wall-mounted collar
• Finish: white
• Application: interior and sheltered exterior wall penetrations

How to use

Position the collar over the prepared wall opening that matches the nominal diameter and secure it to the wall using appropriate fasteners for the wall material. Insert the Ø150 mm duct into the collar and ensure a firm fit; seal joints with suitable duct sealant or tape to achieve airtight connection. For external terminations, verify that the collar is installed in a sheltered location or combined with an appropriate external grille or hood as required by the installation conditions. Follow local building and ventilation codes when integrating the collar into a ventilation system.

Usage recommendations

Use corrosion-resistant fasteners and a quality duct sealant for long-term airtightness. Inspect the connection periodically and clear any obstruction to maintain airflow. For external exposure use a compatible external grille or hood to protect the collar from direct weathering.
