What it is

The Discal 3/4F Dirt and Air Separator PN16 is manufactured by Altecnic. It forms part of the Altecnic Dirt And Air Seperation range and is designed for use in heating systems. The unit removes dirt particles and trapped air from system water to help maintain circulation and reduce the risk of corrosion.

Signs this part needs replacing

  • Persistent air in radiators that requires frequent bleeding.
  • Cold spots at the bottom of radiators or uneven heating.
  • Noisy system operation, such as gurgling or whooshing from pipework.
  • Black sludge or dirty water discharged when bleeding radiators.
  • Reduced heating efficiency despite correct boiler settings.

Before you order

  • Confirm the connection size (3/4F) matches the existing pipework or isolation valves.
  • Check that the PN16 pressure rating is suitable for the system's operating pressure.
  • Verify the installation location has sufficient space for the separator body and access for servicing.
  • Refer to the manufacturer's instructions for correct installation orientation and flow direction.
