Viratop Automatic Air Vents automatically purges air, micro bubles and other gases from the system into the atmosphere quickly and reliably. Air can be collected at high points or specifically designated collection points.
There is a float-controlled vent valve in air collection chamber of the Viratop. If the float loses buoyancy due to the air that has accumulated in the collection chamber, it sinks and the vent valve opens. Automatically air is purged. The float has enough space to move freely even if there are dirt deposits in the air collection chamber. This ensures to protect the valve mechanism from dirt.
