What it is

The Discal Automatic Air Separator 2F is an Altecnic component that removes entrained air and microbubbles from heating system water. Continuously venting air that would otherwise circulate through radiators and emitters helps keep the system running efficiently and quietly. It is supplied as the Discal 2F model under SKU 551009.

Signs this part needs replacing

  • Radiators need bleeding repeatedly, indicating air is still circulating in the system.
  • Gurgling, whooshing or trickling noises from pipework or the boiler.
  • Pump cavitation noise or vibration caused by air reaching the circulator.
  • Cold spots at the top of radiators despite the system being up to temperature.

Before you order

  • Confirm the existing unit carries the Discal 2F model reference.
  • Check the pipework connection size and orientation of the existing separator against the manufacturer's installation instructions.
  • Verify the system type and operating conditions are suitable for this separator.
  • Have the Altecnic installation literature to hand before fitting.
