## Summary description

Round wall flange AWENTA KO150-27/22 designed for Ø150 mm ventilation ducts. The product integrates a valve mechanism and is intended for mounting at wall penetrations to connect and seal circular ducts. Suitable for residential and light-commercial ventilation systems where controlled airflow and tidy wall finishes are required.

## Long description

The AWENTA Wall flange round KO150-27/22 for Ø150 mm duct with built-in valve is a purpose-made component for connecting circular ventilation ducts to wall penetrations. Designed to provide a tidy finish and an integrated airflow control element, this flange fits Ø150 mm ventilation systems used in residential and light-commercial installations. Its construction ensures a sealed transition between the duct and the wall while allowing the valve to regulate or restrict airflow as required.
Advantages
This round wall flange combines a compact profile with an integrated valve to reduce installation steps and save space at the wall connection point. The built-in valve allows simple adjustment of airflow without adding external dampers, and the flange’s form provides a neat, professional finish to wall-mounted duct terminations. Designed for compatibility with standard Ø150 mm circular ducts, it supports reliable sealing and stable mechanical mounting.
Suitable for
Residential ventilation systems with Ø150 mm circular ducts
Light-commercial ventilation installations requiring wall penetrations
Applications where a tidy wall finish and basic airflow control are needed
Retrofit projects replacing a plain flange or adding a simple damper
Key specifications
Designed for circular ducts with nominal diameter 150 mm
Integrated valve mechanism for basic airflow regulation
Wall-mount flange shape suitable for through-wall installation
Compact dimensions for minimal protrusion from the wall
Material and surface designed for indoor ventilation environments
How to use
Prepare the wall opening to match the flange outer dimensions and ensure the duct end is clean and free of debris. Insert the duct into the flange connection and secure according to standard ductwork fastening methods (e.g., clamps, screws or sealant as appropriate for the installation). Position the flange against the wall and fasten it to the substrate so that the flange provides a tight mechanical connection and sealing surface. Adjust the built-in valve to the required position to regulate airflow during commissioning and subsequent use.
Usage recommendations
For reliable performance, use the flange with Ø150 mm circular ducts only and follow local ventilation installation codes. Check the valve operation during commissioning and re-check seals after final mounting. Where airtightness is critical, apply appropriate sealing materials at the duct-to-flange interface and ensure the mounting substrate is stable and flat.
