Automatic air vents and bleeding valves cannot remove microbubbles or circulating air. Venting devices on boilers and other devices will not remove air that is present elsewhere in the system. By removing the presence of all air, SpiroVent also prevents dirt formation and related negative effects on energy efficiency, failure sensitivity and wear and tear.

The positioning of a SpiroVent air deaerator in the system

SpiroVent Air deaerators are preferably positioned at the hottest point of the installation, the point where the water leaves the heater or where the water enters the cooler.
