What it is

The automatic air vent bottle is a Vokera component fitted to the Compact 28 SE gas boiler. It continuously vents trapped air from the heating circuit, preventing airlocks and circulation noise. The bottle-shaped body houses the float and valve assembly that opens automatically as air collects.

Signs this part needs replacing

  • Water weeping or dripping from the vent body
  • Boiler losing pressure repeatedly with no visible leak elsewhere
  • Gurgling, bubbling or rushing noises from the boiler or pipework
  • Radiators needing frequent bleeding despite no other fault
  • Corrosion or scale build-up around the vent cap

Before you order

  • Confirm the boiler model is the Vokera Compact 28 SE
  • Check the part number 20035019 against the appliance's parts list
  • Inspect the vent area for the source of the leak before ordering
  • Isolate the boiler and drain down as required before fitting
