VITHY® VAS-O Automatic Self-cleaning External Scraper Filter automatically removes particulate impurities on the outer surface of the filter mesh, in an effective way of mechanical scraping. The scrapers are made of stainless steel, which is close to the filter mesh and removes the impurities on the outer surface of the filter mesh.
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 filter receives the raw material through the inlet and passes it through the mesh, the impurities are captured on the outer surface. As impurities accumulate, the pressure difference between the inlet and outlet increases. Once the pressure difference is reached or the predetermined time is reached, the motor will start the scraper equipped with a corrector to scrape off the impurities on the mesh. These impurities are then carried to the collection chamber with the water flow. The sewage system starts automatically at regular intervals. Despite the scraping of impurities and the discharge of sewage, the filter remains operational and continues to perform its filtering function.
● The filter runs automatically and cleans itself according to a pre-set schedule or in the presence of a pressure differential, ensuring the filter is always clean.
● The filter does not require disposable filter consumables, which is beneficial to save costs and reduce the need for environmental disposal.
● The scraper made of PTFE wear-resistant material can effectively remove impurities on the filter and prolong the service life of the filter.
● High-strength filter with precise clearance and smooth surface, easy to scrape off impurities and ensure long-lasting performance.
● The pressure loss in the filtration process is extremely small, the flow rate is stable, and the energy consumption is small, which is conducive to continuous and stable operation.
● The filter system is sealed to prevent leakage of harmful substances and promote safe production.
● The discharged waste liquid contains a high concentration of impurities, which can recover valuable materials and avoid their loss.
● The filter provides a variety of module combinations and automatic modes to meet different filtering requirements.
● Equipped with high-quality geared motor or pneumatic components to ensure reliability and long service life.
● The upper cover of the filter is equipped with an auxiliary lifting device, which is easy to operate.
