Bell & Gossett 97 Air Vent

The Bell & Gossett 97 Air Vent is an automatic, float-type air vent designed for hydronic heating systems. Its forged brass body ensures durability in demanding heating loops, while the 1/8 inch male-thread inlet simplifies installation in standard piping.

The float-type mechanism releases trapped air efficiently, improving system efficiency and eliminating air lock, with a robust temperature rating of 240°F and a pressure rating of 150 PSIG, making it suitable for high-temperature, high-pressure applications. Its compact profile also helps it fit into tight spaces without compromising performance.

Designed for easy integration in residential or commercial hydronic circuits, the Bell & Gossett 97 Air Vent handles air media and mounts neatly in tight spaces. Its compact profile suits tight boiler rooms and mechanical closets, while the corrosion-resistant forged brass construction delivers long service life with minimal maintenance. Ideal for upgrading existing hydronic loops or new radiant heating installations.
