What it is

The Altecnic Discal Brass Automatic Air Separator 3/4 is a brass-bodied automatic air separator from Altecnic's Discal air separation range. It is installed in heating system pipework to separate and remove entrained air and microbubbles from the circulating water.

Signs this part needs replacing

  • Air keeps returning to radiators after repeated bleeding
  • Gurgling, rushing or trickling noises from the pipework during circulation
  • Pump cavitation noise or boiler lockouts associated with air in the system
  • System pressure that will not settle at a steady reading

Before you order

  • Confirm the connection size on the existing installation is 3/4 to match this unit
  • Check there is enough clear space around the installation point for servicing
  • Confirm compatibility with the system water quality and any inhibitor in use
  • Refer to the manufacturer's installation instructions for the Discal range before fitting
