Because they have magnetic cores made with High and Very High Intensity Anisotropic Permanent Magnets, they do not use electrical energy and therefore, there is no risk of burning coils or short circuits and explosions, in addition to heating, common problems in electromagnetic filters, which release impurities when there is a power outage.

Magnetic bars can be built with the following magnets: Ferrite= 1500 Gauss; Neodymium-Iron-Boron (Rare Earths), in magnetic flux densities: Normal= 3000 Gauss, Strong= 4500 Gauss, Extra-Strong= 6000 Gauss, Hyper-Strong= 7500 Gauss and Ultra-Strong=9000 Gauss. Their diameter is 25.4mm in the 1500 to 7500 Gauss models (called ‘‘Series 25’’) and 50.8mm in the 9000 Gauss model (called ‘‘Series 50’’). The temperature range for using magnetic bars is as follows: Ferrite models, up to 150ºC; Neodymium-Iron-Boron models, up to 80ºC (or 150ºC, special, upon request). They can also be built with AINiCo magnets, for temperatures of up to 350ºC.

The “C-1 and C-3” models, intended for forced passages, combine the low cost of Ferrite magnets with a high degree of ferrous separation, thanks to the geometry of the magnetic element, with recesses on the surface, which hide the captured ferrous particles, preventing the liquid flow from dragging them.

When cleaning, the rings (daisies) around the magnetic element are removed and, away from the presence of magnetism, they easily release the swarf trapped in them. They can be supplied in 'buckets' which, as they already have a forced passage, are ready for installation and use.

For cases where it is not possible to create a forced passage (ideal condition for magnetic filters), there is the ‘‘C-2’’ model, which has a long-range magnetic field.

The magnetic filters are made entirely of stainless steel, allowing them to be used with practically any type of liquid, even those with high acidity or abrasion.
