The Fernox CF1 Magnetic Dirt Separator is a high-efficiency magnetic filtration unit designed for closed-loop commercial heating and cooling systems. Available in Standard and High Flow variants, it removes both magnetic and non-magnetic particles from circulating fluid, helping protect system components such as boilers, pumps, and heat exchangers.
Its low pressure drop design supports stable flow and energy-efficient operation, while tool-free maintenance allows fast, safe dirt removal without the need for system shutdown, helping to extend system lifespan and protect key components.

The CF1 Magnetic 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 CF1 Magnetic Dirt Separator is constructed to operate efficiently within glycol-water mixtures up to 50% and is compliant with PED 2014/68/EU.
The CF1 Magnetic 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. 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%)
Operating Principle
As the system fluid enters the CF1, the internal geometry slows down the flow to create a separation zone.
Ferrous particles are captured by the dry-pocket housed neodymium magnet, while heavier non-magnetic particles settle to the bottom of the chamber.
Collected contaminants are removed through the integrated drain valve during maintenance, without requiring system shutdown.
The design enables effective removal of circulating debris while maintaining system operation.
Flow Capacities:
• Standard Flow: up to 1.5 m/s
• High Flow: up to 3.0 m/s
• Body Material: Carbon steel
• Internal Coating: Corrosion-resistant
• Magnet: Neodymium, housed in dry pocket
• Drain Valve: Brass
