VITHY® VAS-I Automatic Self-cleaning Internal Scraper Filter automatically removes particulate impurities on the inner surface of the filter mesh, in an effective way of mechanical scraping. The scrapers are made of PTFE/stainless steel, equipped with high-precision springs, which can accurately expand and stretch. The scrapers are close to the surface of the filter mesh, and can efficiently remove impurities.
When the impurities accumulate to a certain extent, the automatic sewage valve opens and the impurities are discharged from the bottom sewage outlet. The filter is suitable for high impurity content and continuous uninterrupted production conditions, for it 1) can realize continuous in-line filtration and 2) particulate impurities recovery, 3) generates no filter consumables, and 4) does not need frequent manual cleaning.
The raw material enters the filter from the inlet and is filtered through the filter mesh, and impurities are trapped on the inner surface of the filter mesh. As impurities accumulate, the pressure difference between the inlet and outlet gradually rises. When the differential pressure or time reaches the set value, the motor drives the scrapers equipped with a corrector to rotate close to the surface of the filter mesh to scrape off the impurities. Impurities flow down with the stream to the collection chamber. The sewage system is automatically turned on regularly. During the impurities scraping and sewage discharging process, the filter keeps filtering.
● Automatic self-cleaning feature ensures constant cleanliness without the need for disposable filter consumables, saving costs and reducing environmental disposal.
● PTFE wear-resistant scraper effectively removes impurities, extending filter's service life.
● High-strength filter with precise gaps and smooth surface ensures long-lasting performance and easy impurity removal.
● Minimal pressure loss, stable flow rate, and low energy consumption allow for continuous and stable operation.
● Sealed filter system prevents harmful substance leakage, promoting safe production.
● Discharged waste liquid contains high concentration of impurities for valuable material recovery.
● Filter offers multiple module combinations and automatic modes for various filtering needs.
● Equipped with high-quality geared motor or pneumatic components for reliability and long service life.
● Easy operation with auxiliary lifting device on upper cover of the filter.
