What it is

The Altecnic Discal Automatic Air Separator is a device fitted into heating and boiler system pipework to separate and remove entrained air from the circulating water. This version has a DN100 welded socket connection and is supplied with insulation. It forms part of the Altecnic Discal air separation range.

Signs this part needs replacing

  • Persistent gurgling or air noise in the pipework that does not clear after venting
  • Radiators requiring frequent bleeding, or recurring cold spots at the top of radiators
  • Reduced heating output despite the system being correctly balanced and pressurised
  • Weeping, corrosion staining or visible damage at the separator body or its welded socket connections

Before you order

  • Confirm the pipework size and connection type match a DN100 welded socket
  • Check the existing separator's markings so the correct Discal unit is ordered
  • Confirm whether the insulation jacket on the existing unit is intact or needs replacing with the separator
