Automatic air vent 1/2 inch, straight Flexvent 89000

Automatic air vent – reliable removal of air from the installation

This Flexvent automatic air vent is a simple yet effective solution for removing air from heating and air conditioning systems. Made of brass, it ensures durability and corrosion resistance. Its compact size makes it easy to install even in hard-to-reach places where air accumulates. This is an ideal solution for both professional installers and end-users who want to maintain optimal performance of their installation.

Construction and application

The Flexvent float air vent operates on the principle of buoyancy. The float inside the device rises with the water level, closing the air supply. When air appears in the installation, the float drops, opening the valve and allowing it to be removed. This ensures that the venting process takes place automatically, without manual intervention. The device is designed for use in installations with a maximum working pressure of 10 bar and a medium temperature of up to 90°C. The brass body provides strength and resistance to external factors.
