This company recently introduced a magnetic filter (photo) that captures very tiny iron particles (as small as 1µm in diameter) in industrial liquids, such as lubricating oil, solvents and coolants. Removing iron particles from such products reduces damage to machines and tools, cuts machine downtime and extends the life of other filters present in the process and the industrial fluids themselves. The magnetic filter can be placed either before or after a candle filter. Installation before will extend the service life of the candle filter, and installation after will ensure separation of the finest iron particles. The magnet is oriented parallel to the main flow, which means that filtering takes place continuously, without stopping the main flow. Unlike other filters, this magnetic filter requires no flushing fluid, so there is very little loss of the original fluid. The capacity of one filter unit is approximately 0.8 m 3 /h and the maximum pressure is 1.5 bars. Multiple filter units can be placed in parallel, which results in a proportional increase of the capacity. — Goudsmit Magnetics Group, Waalre, the Netherlands
