Liquids and powders in pressure lines up to DN300
This very robust magnetic filter is suitable for many industrial applications where liquid mixtures and powders are transported in pressurized pipelines up to 10 bar.
For example removing steel wire from paper pulp. Read more about this application in the news article on magnetic filter for paper pulp.

Filtering & discharging of ferrous contaminants
How does the magnetic filtering work?
The magnetic unit with very strong neodymium magnetic bars is positioned in the middle of the product flow. The product with ferrous impurities passes several magnetic bars while flowing through the filter.
The magnets attract passing ferromagnetic contaminants. The captured particles stick to the magnets, while the purified product flows further.
How does the cleaning / iron discharging work?
Cleaning of the magnetic rods is partly manually (over guide rods) and partly automatically (pneumatically controlled).
Once the product stream is stopped, you pull the complete magnet unit out of the product channel over the guide rods. Then the magnetic rods are pneumatically 'blown' to the OUT position, at which point the Fe particles fall off of the tubes.
Cleaning / iron discharging sequence
- Stop the product flow.
- Loosen the srew connections of the magnet unit.
- Slide the complete magnet unit out of the housing.
- Slide the magnet unit out of the extractor unit.
Catch the ferrous particles that now will fall off the tubes and dispose them.
- Wipe clean all parts with a soft cloth and - if necessary - a suitable cleaning fluid.
- Slide the magnet unit back into the extractor unit.
- Slide the complete magnet unit assembly back into the housing.
- Re-tighten the screw connections.
- Restart the product flow.
