The Ubbink Haelix Clean Zone Valve Insert is a simple but highly effective accessory designed to fine-tune airflow direction from Haelix ventilation valves. By blocking one third of the valve outlet, it creates a defined “clean zone” where no direct airflow is discharged.

This makes it ideal for situations where Haelix valves are positioned close to walls, corners, or occupied areas. The insert helps prevent uncomfortable draughts in habitable spaces while also reducing the risk of dirt deposits and marking on nearby walls—small detail, big difference, just as the old hands would insist.

Easy to fit and discreet once installed, the Clean Zone Valve Insert improves comfort, cleanliness, and long-term appearance without affecting overall system performance.
