What it is

The Discal Automatic Air Separator 1/2F is an Altecnic air separation device for heating and boiler installations. It continuously removes entrained air and microbubbles from system water, helping to maintain flow and reduce noise and corrosion within the circuit. The body is fitted with a 1/2-inch female connection.

Signs this part needs replacing

  • Persistent gurgling, hissing or air noise at radiators and pipework despite repeated venting
  • Cold spots or uneven heat distribution caused by trapped air in the system
  • Water weeping from the separator body, cap or connection
  • Corrosion and sludging accelerated by ongoing air ingress

Before you order

  • Confirm the pipework connection size and thread type match the 1/2 inch female fitting
  • Check the installation position provides access for the separator body and any venting
  • Verify the system is fully drained and isolated before removal of the existing unit
  • Check that the appliance and system type are suitable for an automatic air separator
