Permanent Tube Magnets are used where manual removal of ferrous metals is possible. The housing of these tube magnets provides to the magnet core for cleaning by means of a hermetically sealing door. In the smaller types, the magnet core is fitted to the door, making it easily accessible for cleaning. In the largest types, the magnet is mounted on a sliding carrier so that it can be partially withdrawn from the housing.

Rare Earth Tube Magnets are made from NdFeB Magnets, a high quality RE Permanent Magnetic Power source which develop magnetic fields up to 25 times stronger than conventional Ferrite / Strontium / Alnico units with no increase in size. The additional strengths improves the removal of weakly magnetic or very fine iron contaminants from a wide variety of powders, dry bulk materials as well as from slurries. This extreme high intensity Tube Magnets has applications wherever a high degree of product purity is required. Rare Earth Tube Magnets are effective in removing very fine ferrous particles locked particles and even strongly paramagnetic particles. Magnetic lines of flux are concentrated in each internal pole, creating an extremely high-gradient magnetic field.
