Heating Water Filter Heating Filter Magnetic Sludge Separator Filter FDM-2B

with 3/4" brass thread

The heating water filter removes magnetic and non-magnetic particles, especially corrosion deposits detached in older heating systems.
Impurities from heating, cooling, and solar systems. Iron-containing impurities as well as non-magnetic impurities and sludge are filtered out of the heating water.

A magnetic sludge separator (heating water filter) offers a range of benefits for heating systems – especially for water-based systems with radiators or underfloor heating. Here are the key advantages Advantages and Benefits At a glance:


🔧 Advantages of a magnetic sludge separator:

  1. Removal of magnetic particles (e.g., iron oxides / magnetite):

    • Prevents deposits in radiators, heat exchangers, and valves.

    • Protects sensitive components such as circulation pumps or heating valves.

  2. Protection against corrosion:

    • Iron particles promote corrosion in the heating system. A filter significantly reduces this effect.

  3. Efficiency improvement of the heating system:

    • Less buildup = better heat transfer.

    • Fuel consumption may decrease because the system operates more efficiently.

  4. Extending the lifespan of the heating system:

    • Less wear and tear thanks to clean heating water.

    • Saves on repair and maintenance costs in the long run.

  5. Simple maintenance:

    • Most filters can be cleaned or rinsed without much effort.

    • Magnets can be easily removed for cleaning.

  6. Improvement of water quality:

    • Also protects against non-magnetic suspended particles (with combination filters).

    • Promotes compliance with VDI 2035 (recommendation for water quality in heating systems).

  7. Ideal for renovation or retrofitting:

    • Especially recommended for older systems with steel pipes or cast iron radiators.


Practical use:

  • Fewer disruptions and outages.

  • Reduced maintenance effort for specialist companies.

  • Sustainable operation of the heating system – ecological & economical.

  • A worthwhile investment for new installations or retrofitting.
