Magnetic filtration is widely used in the automotive industry within OEMs and Tier 1 and 2 suppliers for the manufacture of powertrain and engine components. It overcomes the problems associated with traditional filtration systems through its ability to extract sub-micron ferrous contamination without the need for any consumable items. Traditional filter systems such as cartridges, candles, paper filters and hydrocyclones typically only filter out particles >10 microns.
Utilising high intensity magnetics removes the reliance on these consumable items and this can reduce the cost of filtration and downtime. Magnetic filtration systems ensure that fluids run cleaner and retain their qualities for longer. In some applications, fluid life can be extended by up to 10 times.
Purity of the grinding fluid is critical to producing a high quality finish within a precision components operation, and here we can take a look at the results of fitting magnetic filters at a number of leading manufacturers.
