●Armstrong Free Lever Float Air Vents are designed to automatically and continuously remove entrained and trapped air from pressurized fluid systems during operation. Featuring a durable stainless steel body and a precision free lever float mechanism, these air vents provide reliable performance, excellent corrosion resistance, and long service life in demanding industrial environments.

●By eliminating air from steam, hot water, glycol, HVAC, and industrial cooling systems, Armstrong Air Vents improve heat transfer efficiency, reduce pump cavitation, minimize corrosion, and increase overall system reliability. They are widely used in industrial plants, HVAC systems, district heating, glycol circulation systems, data center liquid cooling, and petrochemical facilities.
