Introducing the External Automatic Self-cleaning Filter-your ultimate solution for seamless liquid filtration! Expertly crafted for exceptional efficiency, these filters are specifically tailored to handle a wide range of liquids, even those with high viscosity levels, reaching up to an impressive 800,000 cps. Embrace continuous, uninterrupted filtration without the hassle of stopping the flow during the cleaning process. With no need for operator contact, safety is paramount. Built with superior stainless steel elements, these filters excel at eliminating contaminant particles as minute as 25 microns (μm). The TSW filter is your answer to eliminating frequent manual cleaning woes, significant investment demands, labor-intensive operations, and substantial material waste. Benefit from advanced self-cleaning technology that consistently maintains the filter element's cleanliness, efficiently expels waste liquids rich in impurities, and significantly curtails material wastage. Moreover, our filters effortlessly handle poor water quality and viscous substances like adhesives, resins, polymers, and fats. Experience unparalleled filtration efficiency and discover the advantages of a system designed to optimize your operational productivity!
Experience the advanced mechanism of our Self Cleaning Filter, meticulously crafted for handling both water and viscous liquids. This innovative filter system welcomes liquid through its inlet, allowing it to flow inwardly from the exterior of the filter element. Here, the liquid embarks on a seamless journey from the lower end of the element, smoothly exiting via the outlet. As impurities begin to accumulate on the surface, our sophisticated cleaning procedure is activated, either at pre-set intervals or triggered by a specific pressure differential. A reduction motor ingeniously powers a scraper gliding along the filter's surface, effectively detaching impurities and allowing them to cascade downwards into the filter's basin. Our dynamic sweeping plate then gently guides heavier particles into a designated sewage collection chamber. At predetermined times, an automated drain valve releases the impurity-laden liquid, clearing the system of high-concentration residues. For sustainability-conscious operations, the expelled liquid can be conveniently reintroduced into the process, making our filter not only efficient but eco-friendly.
