IR LEDs

Air vents, also known as air eliminators, are sections of piping which attach to a main pipe to trap and release air. They are designed for use in heating systems to remove air from industrial and/or commercial hot and chilled water systems. They are vital to ensure correct system pressure and to manage oxygen saturation.

Applications include:
  • Automatic air vents
  • Liquid systems
  • Thermostatic air vents for steam systems
