A vacuum filter is a key equipment that achieves solid-liquid and gas-solid separation through vacuum negative pressure. Its core working mechanism can be summarized as three steps: negative pressure adsorption medium interception automatic waste discharge. With the help of a vacuum pump, a stable negative pressure (usually -0.05 to -0.09 MPa) is formed in the filtration chamber, driving the material to pass through filter media such as filter cloth and membrane at high speed. Impurities are intercepted to form a filter cake, and the purified fluid is discharged through a vacuum tube. The new generation of equipment achieves a leap from "extensive separation" to "precise purification" through multi-stage filtration unit series connection and intelligent pressure regulation technology, with a filtration accuracy of up to 0.1 microns, suitable for industrial wastewater treatment to semiconductor cleaningNet equivalent diverse scenarios.
