KOBOLD’s MFR magnetic filters are used extensively in cooling and lubricating circuits. the MFR provides protection from ferritic particles which have either precipitated out of solution or, in the case of machining applications, have been carried away from the milling operation. Use of this filter is the insurance which protects you from expensive repairs caused by mechanical erosion of internal parts, or downtime caused by build-up and clogging of equipment and supply lines.
