What it is

The Discal Automatic Air Separator is an Altecnic product for air separation in heating and boiler systems. It removes entrained air and microbubbles from circulating water, helping to maintain flow and protect system components. This version has a DN50 flanged connection and a PN16 pressure rating.

Signs this part needs replacing

  • Persistent air noise or gurgling in the system despite the separator being fitted
  • Repeated air locking at radiators or high points that does not clear
  • Water weeping or dripping from the separator body or flange joints
  • Corrosion, scale build-up or blockage visible around the unit
  • System pressure that will not hold steady due to air ingress

Before you order

  • Confirm the connection size and type required, as this unit is DN50 flanged
  • Check the system pressure rating is compatible with PN16
  • Verify the installation position and clearance available for the separator
  • Check the system volume and flow rate against the separator's duty
