What it is

The Altecnic Discal Brass Automatic Air Separator 28mm is an automatic air separation device manufactured by Altecnic. It removes entrained air and microbubbles from the system water in heating and boiler installations, with 28mm connections and a brass body.

Signs this part needs replacing

  • Persistent air noise or gurgling through the pipework despite correct system pressure
  • Radiators that repeatedly require venting
  • Cold spots or uneven heating caused by trapped air circulating in the system
  • Pump cavitation or erosion noise linked to air remaining in the water
  • Visible leaks, corrosion or weeping at the separator body or connections

Before you order

  • Confirm the pipework and connections are 28mm before installation
  • Check the existing separator's position and orientation, as the unit must be fitted to allow air to rise and vent
  • Isolate and drain the relevant section of the system before removing the old unit
  • Verify the system is a sealed heating circuit suitable for an automatic air separator
