Description
The Watts 0590719 1/8″ Duovent High Capacity Air Vent with manual vent feature is a hydraulic system component used to automatically remove trapped air from hot or cold water loops in HVAC systems. It works using an internal float mechanism that opens and closes the vent outlet based on air accumulation, while the manual cap allows quick system bleeding when needed. It is used in boilers, radiant heating, and chilled water systems, and it improves circulation efficiency, prevents airlock issues, and supports stable pressure balance. It enhances heat transfer, reduces noise and ensures reliable performance in systems.
