An automatic flanged air vent is a device commonly used in plumbing and HVAC systems to automatically remove trapped air or gas within closed piping systems or equipment. Its automatic operation ensures that it opens and releases trapped air without manual intervention, maintaining system efficiency. The term "flanged" indicates the presence of flat, projecting rims with bolt holes, allowing easy installation and secure connection in the system. By eliminating trapped air, these vents prevent issues such as airlocks, ensuring smooth and efficient operation of the system.
