Rare Earth Magnetic Filtration
Flow Pro Products’ high strength rare earth magnetic filters deliver high performance filtration levels for minimally ferrous materials such as high speed steels, tool steels and carbides, and final metalworking processes for close tolerance component manufacturing. These filters are capable of maintaining machine tool coolants to 10 micron nominal clarity, without the need for consumable filtration media. Processes like super-finishing, honing, micro-sizing, lapping and burnishing generate extremely small particulate and make filtration operations very challenging, expensive and maintenance intensive.
The system is capable of removing all solid particulate (magnetic and non-magnetic) down to a nominal clarity of 10 microns, yielding an average particle loading of 50 PPM or less. These Rare Earth Magnetic Filtration Systems eliminate the operational expenses of purchased filter media and filter-aid powders. They also eliminate the maintenance intensive chores involved in operating complicated filtration processes. What distinguishes Flow Pro Products’ line of Rare Earth Magnetic Filters is the extended pole design, high power Neodymium Iron Boron drum construction, and the logic employed to index the drum, automatically on demand. Compared to smooth cylindrical drums that rotate continuously, the raised pole design employs 40% more magnetic surface area per linear foot.
The drum is designed to index on demand and does not rotate continuously, so the captured contaminants that are discharged are drier, and that in turn reduces coolant loss. Our automatic indexing control logic will only rotate the drum when the fluidic probe generates a signal, as the captured contaminants continue to build up in the intense magnetic field. The purpose behind this circuitry is to maintain the optimum porosity of the filter matrix, which is dictated by the application, flow rate and the sizing selection. This results in the most reliable and efficient filtration and removal of magnetic and non-magnetic contaminants from metal working coolants. These units can achieve 10 micron nominal coolant clarity and the removal of 99% of all grinding fines over 10 micron.
