Flamco Flexvent Super Automatic Air Vent 1/2"

With a compact and proven design the flexvent super has high efficiency rating and guaranteed operation for heating and air conditioning and is easy to fit in any installation due to its very small dimensions.

The water within the system contains air which can cause corrosion and reduce the thermal transfer. A Flexvent is fitted at places in the system where the air collects and it operated by a float, when air is collected in the Flexvent it causes the float to drop and open the air release valve, when the air is eliminated the float rises and closes the valve.

Flexvent float vents are made of brass and most types are equipped with shut-off valves for easy fitting and dismantling. The relatively large air cushion at the top of each type of Flexvent float vent protects the valve seat sufficiently against contamination, so that the Flexvent will not Leak.

To guarantee top quality, all Flexvents are tested before they leave the factory.


The cap of the Flexvent Super is conical in shape. The advantage of this construction is that the clearance between the water level and venting valve is maximized. 
The air escape duct can be opened or closed with an adjusting screw. 
The venting valve forms an integral part of the cap, so that it is impossible to damage the floatvent mechanism from outside.
The relatively large air cushion at the top of each type of Flexvent float vent protects the valve seat sufficiently against contamination, so that the Flexvent will not leak. 
To guarantee top quality, we test all Flexvents before they leave our facility!
