It efficiently removes trapped air to prevent corrosion and improve heat transfer, operating reliably up to 120°C and 10 bar pressure. Featuring a contamination-protected valve seat and an integrated shut-off valve, it ensures leak-free performance and easy maintenance, making it a trusted choice for millennial professionals seeking durable, high-quality HVAC solutions. ## Description The compact, proven design ensures highly efficient and reliable operation. The water inside a system contains air pockets, which can lead to corrosion damage and a reduction in heat transfer. The installation of a Flexvent float bleeder is ideally done at the highest point in the system system. If air accumulates in the float vent, this causes the float to sink in the housing and opening of the air release valve. Most Flexvent types are equipped with a shut-off valve for easy installation and removal. The Flexvent float bleeder can be easily installed in any system due to its small dimensions. The air cushion in the upper housing part protects the valve seat sufficiently against dirt, so that the Flexvent does not leak. To ensure excellent quality, we check all Flexvents before delivery. In pressed brass finish with gunmetal effect, complete with pre-sealed shut-off device (except Flexvent ½" white) and plastic cover cap with integrated source rings to prevent leaks caused by possible contamination. Suitable for glycol-based antifreeze additive up to 50%. Maximum operating pressure: 10 bar. Peak temperature resistance: 120 °C.
