What it is

The Discal Automatic Air Separator is an Altecnic component for removing entrained air and microbubbles from the water circulating in a heating system. This version is supplied with DN125 welded socket connections and forms part of the Altecnic air separation range. It sits within the pipework of the system, continuously separating air without needing manual venting.

Signs this part needs replacing

  • Persistent air noise or gurgling in the system that does not clear after venting
  • Repeated airlocks at high points, pumps or heat emitters
  • Cold spots or uneven heat distribution caused by trapped air
  • Rising corrosion or sludge build-up linked to dissolved oxygen in the water
  • Visible leaks or weeping from the separator body or its connections

Before you order

  • Confirm the pipework connection size is DN125 before ordering
  • Check that the welded socket connection matches the method used on the existing installation
  • Verify compatibility with the existing Altecnic air separation arrangement
  • Check the available space and support requirements for a unit of this connection size
