- The coolant contaminated with impurities arriving by gravity from the water jet system is loaded on the Demag magnetic filter with self-cleaning drum, made of AISI 304 stainless steel (if magnetic material is processed) or distributed by the trough on the fabric filter (if non-magnetic material is processed).
- The filter fabric, duly chosen for its weight and degree of filtration, retains the polluting particles and allows the liquid to flow into the collecting tank below.
- The tissue progressively accumulates polluting particles, increasing the degree of filtration until it becomes clogged. At this point, the liquid is no longer able to pass through the filter fabric, so it rises to level, lifting the float, which activates the microswitch and controls the advancement of the conveyor and the consequent replacement of the consumed fabric with the new one.
- The consumed fabric is collected in a special tank located at the head of the purifier, while the pre-filtered liquid collected in the tank below is sent by means of the special electric pump, controlled by two electromechanical levels, to the 3μ superfiltration cartridge, which is also inserted in an AISI 304 stainless steel tank and from which the superfiltered liquid is discharged by gravity.
- The 3 micron superfiltration cartridge is fed by a pump whose start and stop is controlled by two independent electromechanical levels. The hydraulic connection unit, equipped with a pressure switch, gives indication of cartridge clogging/ replacement.
