AE14 Automatic Air Vent – Spirax Sarco
The AE14 from Spirax Sarco is an automatic air vent for liquid systems. It is a robust and serviceable solution that automatically removes air and gases from fluid-filled pipes and equipment without losing any liquid.
Working Principle
The AE14 operates on a sealed float mechanism. When air accumulates, the liquid level inside drops, opening the valve to vent the air. Once liquid returns, the float rises and closes the valve. The process is fully automatic and requires no manual intervention.
