Air Vents

Armstrong air vents employ a free-floating lever design to discharge non-condensable gases. This float-operated design allows the vents to instantly and automatically adjust to variations in gas flow and pressure, increasing system efficiency. Armstrong air vents can remove gas from liquids with gravities as low as 0.40 and pressures to 2,700 psi (186 bar). Armstrong air vents are available in a variety of sizes, end connections, and materials. Applications for Armstrong float-type air vents include hydronic heating systems, water service lines, water storage tanks, centrifugal pumps, gas lines, solvent filters, and similar equipment.
