Magnetic Filter Immergas MG1 – scale and debris separator for central heating systems

Immergas MG1 is a magnetic filter for central heating systems that separates ferrous particles, magnetic contaminants and debris from circulating water. Designed for inline installation in heating circuits, the device captures metallic sludge and scale that can damage boilers, radiators and pumps. The compact housing and strong magnetic core provide continuous protection to reduce the frequency of mechanical failures and support stable heat transfer in sealed heating systems.

Advantages

The Immergas MG1 combines magnetic separation with a removable collection chamber to retain metal particles and coarse debris without interrupting system operation. Its compact dimensions and standard connection format allow straightforward integration into most residential and light-commercial heating circuits. Routine cleaning is simple: the trapped material is retained in the filter body and can be discharged during scheduled maintenance, protecting circulating pumps, heat exchangers and control valves from abrasive wear and blockage.

Suitable for

• Domestic and small commercial central heating systems
• Systems with boilers and circulating pumps requiring magnetic separation
• Retrofit applications in existing heating circuits
• Installation on return lines where magnetic contaminants concentrate

Key specifications

• Function: magnetic separation of ferrous particles and retention of coarse debris
• Installation type: inline filter for central heating circuits
• Material: corrosion-resistant housing with magnetic core (factory-specified materials)
• Maintenance access: removable collection chamber for periodic flushing
• Connection: standard threaded connections suitable for typical heating pipe sizes (verify local piping compatibility)

How to use

Install the Immergas MG1 in the return line of the heating circuit where magnetic particles tend to collect, following the system layout and flow direction markings. Ensure the unit is compatible with pipe size and mounting orientation and is accessible for maintenance. During operation the magnetic core attracts and retains ferrous contaminants; periodic inspection and flushing of the collection chamber remove accumulated particles. Always isolate the unit and relieve pressure in the circuit before opening the drain or removing parts for cleaning.

Usage recommendations

Check compatibility with your boiler and loop piping before installation. Schedule regular inspections as part of routine system maintenance—frequency depends on system age and water quality. When cleaning, wear appropriate protective gloves and follow safety procedures for working on pressurized heating systems. If unsure about installation or maintenance, consult a qualified heating technician.
