Magnetic filtration – are you using it?

Magnetic filters are commonly used during the manufacturing stage in the automotive industry. By producing a magnetic field or loading zones that collect magnetic iron and steel particles, magnetic filters can often outperform traditional, mechanical filters. In many machines as much as 90% of all particles suspended in the oil can be iron or steel […]
