Introduction to products
    The conventional differential pressure type filtering machine (self-cleaning filter )can only be used in the coarse filtration industry, the main reason of which attributed to that when the high-precision filter screen is adopted, the filter screen is blocked by the dirt which can not be cleaned thoroughly as the main body of the filtering machine is not provided with the reliable high-pressure back flushing function, thereby the flux of the filter screen can not be recovered, and the filtering machine can not perform the normal operation.
    The Century Source double-grade intelligence controlling differential pressure filtering machine makes a beginning of the high-precision filters as provided with the unique high-pressure back flushing function, which is the only micro-filtration product in which the filtering element is not required to be replaced and the flux of which can be recovered quickly under the state of uninterrupted water. The particular patent technique can ensure the reliable quality and the most valuable competition advantage of the market. Actually, the transient high precision can be achieved easily only through adopting the more precise filtering element; however, we not only intend to meet the requirements for precision, but also desire to discuss and solve the fouling problem, since if the perfect cleaning function is not provided, the precision can not be achieved.
    What the users care about is how to realize the stable operation on the premise that the quality of the water used by them is satisfied. We realize the retention of the system performance and on-line recovery, which is a qualitative breakthrough on the micro-filtration products that take metal material as the filtering element; thereby the gap of the filed is filled.

Functions 
    The filter is mainly applied to purify water, especially in micro-filtration field where stricter requirements are made for the water quality. The main function of the filter is to remove such impurities as silt, clay, rust, suspended substances, algae, bioloam, corrosion products, macromolecule bacteria, epiphyte, organic matters, protozoan and other small particles in water so as to purify water.
