Resideo FV180 Automatic Air Vent | 1/8 Inch NPT | 150 PSI Max

Description

The Resideo FV180 Automatic Air Vent delivers reliable, hands-free air elimination for hydronic heating and cooling systems — keeping circulation optimized and system performance at its peak. Trapped air is one of the leading causes of reduced efficiency, noisy pipes, and accelerated corrosion in closed-loop systems. The FV180 addresses this directly with automatic venting that requires no manual intervention, making it an ideal solution for both residential and light commercial installations.

Featuring a 1/8 inch NPT connection, the FV180 integrates seamlessly with standard hydronic fittings and components. Its compact footprint makes it well-suited for tight mechanical spaces where larger vents simply won’t fit, while its durable construction ensures long-term, dependable service life.
