Amtrol 700-30 Float Type Air Vent with a 1/8 in NPT connection is a compact device designed to remove trapped air from closed-loop systems and help maintain steady flow. Its float-type mechanism responds to changes in liquid level, allowing air to vent as air accumulates and automatically resealing as liquid returns. The 1/8 in NPT port accepts standard fittings for installation into compatible piping, valves, or manifolds, enabling flexible placement in tight spaces. This vent is suitable for small-to-medium hydronic or other closed systems where air buildup can impede circulation or lead to noise and reduced efficiency.
