What it is

The Ferroli 39849790 is an air separator supplied for the flow pipe on selected Ferroli condensing appliances. It removes entrained air from the heating circuit water as it leaves the boiler, helping to protect the pump, heat exchanger and radiators from air-related circulation problems. It is listed for use across the Modena HE and T-ONE 25C HE ranges.

Signs this part needs replacing

  • Persistent air noise or gurgling from the boiler or pipework after repeated venting
  • The system needs bleeding frequently, with air returning shortly afterwards
  • Poor circulation or uneven radiator heating that points to air being carried around the circuit
  • Visible corrosion, scale build-up or physical damage at the separator body or its connections
  • Water weeping from the separator or its joints

Before you order

  • Confirm the appliance model against the fit list above, as the separator is listed for specific Modena HE and T-ONE 25C HE variants
  • Check the GC number on the appliance data badge against the model you are working on
  • Verify the existing part number 39849790 on the component being replaced
  • Inspect the surrounding flow pipe and connections for damage before fitting
