What it is

The Altecnic Discal Automatic Air Separator is a flanged air separation device for heating system pipework. It removes entrained air and microbubbles from system water, helping to keep circulation stable and reducing air-related noise and corrosion risk. This version has a DN65 flanged connection and a PN16 pressure rating.

Signs this part needs replacing

  • Persistent gurgling or rushing noises in the pipework that continue after venting
  • Radiators that repeatedly need bleeding shortly after being bled
  • Cold spots at the top of radiators or uneven heat distribution across the system
  • Circulation pump noise or cavitation symptoms suggesting air is still present
  • Visible leaks or weeping from the separator body or flange joints

Before you order

  • Confirm the pipework connection is DN65 flanged and matches the existing separator
  • Check the system operating pressure does not exceed the PN16 rating
  • Verify the flange drilling and bolt pattern suit the installation
  • Confirm the existing appliance or system arrangement matches the Altecnic air separation application
