The Protex Magnetic Filters work by creating a loading zones that collect magnetic iron and steel particles. Magnets are geometrically arranged to form a magnetic field having a non-uniform magnetic strength. Particles are most effectively separated when there is a strong magnetic gradient (rate of change of field strength with distance) from low to high. In other words, the higher the magnetic gradient, the stronger the attracting magnetic force acting on particles drawing them toward the loading zones. The strength of the magnetic gradient is determined by flux density, spacing and alignment of the magnets. Water flows in through the redirector then enters the middle part of the magnetic filter, ferrous particles are then drawn by the magnetic rod, non-ferrous particles will be filtered by Stainless steel mesh. Filtered water will flow along the interior wall and finally flow out of the magnetic filter. The unit can be easily installed on a vertical or horizontal return flow pipework to the boiler.
