Armstrong is committed to sustaining the needs of future generations by conserving and saving energy and implements this throughout its product line.
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.
Drain Separators
Steam Traps

Armstrong offers a full range of steam traps, including bucket steam traps, float and thermostatic (F&T) traps, and their repair parts. These traps efficiently move condensate, air, and CO2 out of steam systems. This operating efficiency means less fuel is burned, in turn reducing emissions and saving money. Armstrong steam traps provide minimal steam loss, long life and dependable service, corrosion resistance, operation against back pressure, and little to no dirt problems.
