Vacuum Filter

The vacuum filter is a conveyorised tank with a vacuum septum under.The floor of the tank, separating these two sections, is made ofperforated plate. A paper media is then placed over the perforatedplate, and held tight to the plate by a flight bar conveyor. The papermedia is supplied on a roll, which is supported at the end of the tank.The dirty coolant is discharged into the top section of the tank. TheSystem pumps draw coolant through the media into the vaccum chamber,and then onto the machine tool. A percentage of clean coolant istransferred to a clean tank mounted above the dirty tank. This tankremains full at all times to support a regeneration when required. Whenthe paper media becomes blocked with debris, the vacuum will rise to aset point.  When reached,  the clean coolant stored in the Clean tankwill discharge into the vacuum chamber releasing the vacuum.Simultaneously the conveyor will index allowing a certain length of newclean media to enter the filtration area. The system resets after thisregeneration period, and the system pumps then begin to build a vacuumagain in the vacuum chamber. The spent media is automatically scrappedclean and then rewound onto a mandrel for disposal. The vacuum Filtercan be used for single or multiple machine tool installations. Thevacuum filter is suitable for a clarity down to 15 micron. However,this figure is only achievable if a cake is built up on the media,which creates a very thick additional filter to the paper media. Thisis usually found only on grinding processes. Filtration clarity can bedown to 8 microns in this instance. Clarity is dependant on thematerial being machined, and the type of cutting fluid filtered. Thepaper media also is of paramount  importance,  and can be varied tosuit the material and fluid.
