What it is

The Discal Automatic Air Separator is an Altecnic air separation device for heating and boiler installations. It removes entrained air and microbubbles from the system water automatically, with a DN100 flanged connection and a PN16 pressure rating. It is installed on the system pipework where continuous air removal is required.

Signs this part needs replacing

  • Persistent air noise or gurgling in the system despite venting
  • Radiators or emitters that repeatedly need bleeding
  • System pressure that will not hold steady or keeps dropping
  • Cold spots at the top of radiators indicating trapped air
  • Visible leaks or weeping from the separator body or its connections

Before you order

  • Confirm the pipework size and flange arrangement match DN100
  • Check the system operating pressure does not exceed PN16
  • Verify the installation position allows access for servicing
  • Check the existing separator's connection standard against the flanged fitting
