Bottle Type Automatic Air Vents

More Views


Bottle type automatic air vents are used to remove air within heating systems, the air floats up to the top of the system and triggers the float contained in the automatic air vent to drop causing the valve to open and release the free air. 

To enable the bottle type automatic air vent to work to its maximum potential, the air vent must be fitted at the hottest part of the water system, when fitted and used correctly you will find that the bottle type automatic air vent should:

  • Provide longer system life
  • Ensure low pressure drops
  • Reduce commissioning times
  • Create bi-directional flow
  • Help air to collect before being released from the system
  • Allow you to remove air from the system during its initial fill
