Ferroli Air Dirt Separator 39814300

The Ferroli air and dirt separator, part number 39814300, is a hydraulic component fitted to Econcept boilers. It removes entrained air and suspended dirt from the heating circuit before the water is recirculated through the appliance. Keeping both air and particulate matter out of the system protects the heat exchanger and maintains stable circulation.

• Persistent gurgling, whooshing or rushing water noise from the boiler or pipework
• Radiators that need bleeding repeatedly, or cold spots at the top of radiators
• Boiler lockout or overheat faults linked to poor circulation
• Visible sludge, black oxide or debris collecting in the separator body
• Leaks or weeping from the separator housing or its connections

• Check the appliance data plate to confirm the exact Econcept model and variant
• Confirm the part number 39814300 against the manufacturer's parts list for your appliance
• Distinguish between the standard and commercial Econcept variants before ordering
• Inspect the surrounding pipework and system water quality, as dirt loading often indicates a wider system issue
