The 125mm Air Valve Extract or Supply is a versatile and reliable ventilation component designed for use in suspended ceiling applications. Manufactured by Domus, this air valve can be used for both air extraction and air supply, making it ideal for residential and light commercial ventilation systems.
Designed with flexibility in mind, the range includes three variations to suit different installation and aesthetic requirements. The valve is compatible with both stylish architectural grilles and standard air valve configurations, allowing it to integrate seamlessly into modern ceiling designs.
For enhanced performance and ease of installation, the system can be paired with Flow Control Plenums. These enable straightforward connection to Domus architectural grilles and allow accurate airflow commissioning before ceiling boards are fixed—saving time on-site and ensuring optimal system performance.
A practical, efficient, and aesthetically adaptable solution for controlled indoor air movement.
