Description
The Resideo FV180A is a precision-engineered automatic air vent built to deliver reliable air elimination in hydronic heating and cooling systems. By continuously purging trapped air, it maintains optimal fluid circulation, protects system components from corrosion, and reduces operational noise — keeping your system running at peak efficiency. Its rugged brass construction and compact footprint make it an ideal choice for both residential and light commercial installations, including tight mechanical spaces where larger vents won’t fit.
