Armstrong Stainless Steel Thermostatic Air Vents

Armstrong offers thermostatic air vents for positive venting of air and other non-condensable gases from steam in chamber-type heat-transfer equipment. Typical applications include jacketed kettles, retorts, vulcanizers, jacketed sterilizers or other contained equipment where air could accumulate in remote areas of the steam chamber and reduce heat-transfer capacity. These vents are balanced-pressure air vents that respond to the pressure-temperature curve of steam. Air is automatically vented at slightly below steam temperature throughout the entire operating pressure range.
