Spirax Sarco AV13 Thermostatic Air Vent for Steam Systems

The Spirax Sarco AV13 is a maintainable balanced pressure thermostatic air vent designed specifically for steam systems. It features angled connections and a robust brass body construction suitable for industrial steam applications.

This air vent operates on the thermostatic principle, using a stainless steel capsule that responds to temperature differences between air and steam. When air or other non-condensable gases accumulate in the steam system, the AV13 automatically vents them to atmosphere, ensuring efficient heat transfer and preventing corrosion caused by trapped air.

The AV13 is designed for installation at high points in steam mains and equipment where air naturally collects. It complies fully with the European Pressure Equipment Directive 97/23/EC and is available with manufacturer's Typical Test Reports for documentation requirements.

The Spirax Sarco AV13 air vent is used across various industrial steam applications:

- Steam mains and distribution headers — Installed at high points to vent accumulated air during system startup and operation - Heat exchangers and process equipment — Removes air pockets that reduce heat transfer efficiency - Steam tracing systems — Ensures complete steam filling of tracing lines - Sterilizers and autoclaves — Critical for removing air to achieve proper sterilization temperatures - Jacketed vessels — Maintains efficient heating by eliminating air locks

Industries served include pharmaceuticals, food processing, textiles, refineries, chemical plants, and any facility operating steam-based heating or process systems.
