Resideo FV180 GoldTop Universal Automatic Air Vent 1/8" NPT

The Resideo by Honeywell FV180 GoldTop Universal Air Vent is a revolutionary automatic air vent designed for both heating and cooling hydronic systems. This float-type air vent features a patented fulcrum design that delivers superior venting performance across a wide pressure range from 1 to 150 PSI, making it a true universal solution that replaces multiple specialized vents including the older EA67A1009 model.

Key Features:

• 1/8" NPT male pipe thread connection for easy installation
• Patented fulcrum design provides 3-4 times the venting rate of conventional air vents
• Maximum operating pressure of 150 PSI
• Maximum operating temperature of 240°F
• Built-in vacuum breaker prevents backflow
• Removable float/valve assembly for easy maintenance
• Brass construction for durability and corrosion resistance
• Distinctive gold-colored top for easy identification

Unlike traditional air vents that stop functioning at higher system pressures, the FV180's innovative design maintains consistent venting performance throughout the entire pressure range. This automatic air vent is designed to be installed vertically at the highest points in hydronic systems to efficiently purge air from hot or cold water applications. The one-size-fits-all design simplifies inventory management while ensuring reliable air elimination in residential and light commercial heating and cooling systems.
