What it is

The Altecnic Discal Automatic Air Separator is a flanged inline air separation device for heating and boiler systems. It removes entrained air and microbubbles from circulating water before they reach the boiler and emitters. This version is DN50 with a PN16 flange connection and is supplied with insulation.

Signs this part needs replacing

  • Air noise or gurgling that persists in the pipework despite the separator being in place
  • Radiators, cylinders or high points needing repeated bleeding
  • Reduced heat output or uneven heating across the system
  • Corrosion or sludge build-up in the system consistent with ongoing air ingress
  • Water weeping from the separator body, flange joint or vent assembly

Before you order

  • Confirm the pipework size matches the DN50 flanged connection
  • Check the system pressure rating is compatible with PN16
  • Verify the flange drilling pattern matches the existing pipework
  • Confirm the installation position and clearance allow the insulated unit to be fitted
