Official FilterMAG Distributor
We are now the official Australian Distributor of FilterMAG products. In order for FilterMAG to remove minute steel particles from the oil system, its magnets must have enough energy to hold incredibly fine particles against the velocity of the oil flow.

FilterMag products

FilterMAG's patented design employs a focused magnetic force field, that amplifies its incredibly powerful Neodymium magnets, to generate the immense force needed to forcibly remove tiny particles below 20 micron from the oil flow; and retain increasingly smaller particles - as small as 2 microns - against the pressure of oil flow velocity.
