The Ubbink Haelix Rondo Valve 125mm is a air valve designed for both supply and extract applications within modern ventilation systems. Finished in clean white (RAL 9016), it delivers a smart, contemporary look that sits neatly in any residential or light commercial interior.

Designed to slot seamlessly into Air Excellent valve adaptors, the Haelix Rondo combines ease of installation with precise airflow control. The integrated 9-step airflow restrictor allows quick and accurate adjustment during commissioning, while its low pressure drop and low sound level ensure efficient, quiet operation. A clever flange design helps prevent dust deposits, keeping the valve cleaner for longer and maintaining performance over time.

The valve is also paintable, making it easy to blend into ceilings or walls for a discreet, professional finish—proper craftsmanship, just like it used to be.
