Permanent spout magnets have been specially developed for through removal of ferrous metals from materials in granular and powder from during transport through pipeline systems. These magnet system are built into a housing which is fitted with flat flanges that, after mounting, they from a single unit with the pipeline systems. Guide strips are fitted on the inside of the housing to ensure that the material to be purified is well distributed and comes into good contact with the magnet core.

Permanent spout magnets are used where manual removal of ferrous metals is possible. The housing of these tube magnets provides access to the magnet core for cleaning by means of hermetically sealing door. In the smaller types, the magnet core is fitted to the door, making it easily accessible for cleaning.
