The Fernox CC1 Magnetic Combi Air & Dirt Separator is a high-efficiency device engineered to automatically remove air, microbubbles and magnetic debris from closed-loop heating and cooling systems. Suitable for commercial applications, the unit ensures improved system performance, reduced energy consumption and long-term protection of plant equipment.
The range is available in two versions:
Standard Flow – suitable for velocities up to 1.5 m/s
High Flow – suitable for velocities up to 3.0 m/s
| 33006242/0065 | Flow Rate m/s: 1.5 m/s (standard-flow), DN Size: 65 | |
| 33006242/0080 | Flow Rate m/s: 1.5 m/s (standard-flow), DN Size: 80 | |
| 33006242/0100 | Flow Rate m/s: 1.5 m/s (standard-flow), DN Size: 100 | |
| 33006242/0125 | DN Size: 125 | |
| 33006242/0150 | DN Size: 150 | |
| 33006242/0050 | Flow Rate m/s: 1.5 m/s (standard-flow), DN Size: 50 |
The Fernox Combined Magnetic Air and Dirt Separator is constructed from carbon steel with a corrosion-resistant internal coating, making it ideal for long-term use in commercial plantrooms. The unit incorporates high-strength neodymium magnet housed in a dry pocket, allowing for the safe capture of both non-magnetic and ferrous debris.
Its vertical body and flanged design are optimised for ease of installation and maintenance access. Engineered to deliver minimal pressure loss while maintaining high collection efficiency, the unit includes a drain valve that allow for quick servicing without isolating the system. The Fernox Combined Magnetic Air and Dirt Separator is constructed to operate efficiently within glycol-water mixtures up to 50% and is compliant with PED 2014/68/EU.
The Fernox Magnetic Combi Air & Dirt Separator improves the system efficiency in sealed heating and chilled water systems in commercial environments such as schools, hospitals, and offices. Installed in-line on the flow or return pipework, it prevents system contamination and protects key components including pumps, boilers and heat exchangers. Compatible with water and inhibited glycol solutions, and ideal for systems using chemical inhibitors such as Fernox Protector F9.
Location (Heating systems): On the flow line, preferably after the boiler
Location (Cooling systems): On the return line, close to the chiller
The system operates independently of flow direction. Automatic air vent must remain accessible. Drain valve allows discharge of debris without requiring a system shutdown.

Maximum Operating Pressure: 10 bar
Test Pressure: >15 bar
Operating Temperature Range: 0 – 110°C
Installation Orientation: Horizontal pipework
Connection Type: Flanged (DN50 to DN150)
Suitable Fluids:
• Water
• Glycol-water mixtures (up to 50%)
Flow Capacities:
• Standard Flow: up to 1.5 m/s
• High Flow: up to 3.0 m/s
Operating Principle
As water flows through the Combi unit, microbubbles coagulate and rise and are expelled via the integrated automatic air vent.
Simultaneously, magnetic debris is retained by the neodymium magnet located in a rotatable dry pocket, while heavier particles settle at the bottom of the chamber. These can be removed through the integrated drain valve.
This ensures continuous cleaning without interrupting system operation.

Each unit is hydrostatically tested at >15 bar and shipped pre-assembled. The air vent and drain valves are factory-fitted. The unit must be installed indoors, in a frost-free, ventilated area. System must be depressurised and cooled prior to servicing. Regular drain cycles are recommended every 6 months under normal dirt load.
