Automatic Air VentsAir vents to remove air from pipelines carrying liquids. Super Compact Automatic Air VentsSuper compact air vents for equipment. Air Vents for SteamAir vents to remove air from steam piping and equipment. Benefits and Features The product line-up includes both air vents for use on pipelines for liquids and those for use on pipelines for steam. The air vents for piping carrying liquids make use of Free Float® steam trap technology for a tight seal and excellent durability. There are two types of air vent series for piping carrying liquids. One features a specialized rapid initial air vent to discharge initial air when the supply of liquid begins, and the other features an automatic air vent to discharge air regularly during operation. The air vents for steam piping make use of thermostatic steam trap technology to discharge not only cold initial air, but also hot air. Application Areas Air Vent for Liquid Rapid initial air venting: Water lifting pumps, water transport lines, water storage tanks. Automatic air venting: Air conditioning facilities, solar systems, water transport lines, water storage tanks. Air Vent for Steam Steam heating equipment such as jacketed kettles. Steam main line pipe-ends, etc.
