The Unite U-ZC-G1 series cylinder scraper self-cleaning filterautomatically removes particulate impurities from the inner surface ofthe filter element through mechanical scraping, enabling continuousonline filtration. The U-ZC-G1 filter is primarily designed forhigh-viscosity filtration, suitable for viscosities up to 800,000 mPa.s, witha precision range of 25-100 microns. It provides precise filtration andquickly scrapes impurities from the filter element surface, thus efficientlyremoving more impurities. It is suitable for filtering water and variousviscous liquids.
Traditional filters frequently clog when filtering viscous materials andsoft impurities, requiring the use of large filters or frequent manualcleaning, resulting in high investment, heavy workload, and significantmaterial waste. The U-ZC-G1 filter easily solves these problems with itsadvanced self-cleaning method, consistently maintaining a clean filterelement and discharging waste liquid containing high concentrations ofimpurities, reducing material waste. It offers significant advantages andhigher efficiency when filtering poor-quality water and viscous materialssuch as adhesives, resins, polymers, and oils.
The Unite twin-cylinder self-cleaning filter system is shown in thediagram. The incoming fluid
(1) is filtered from the inside out throughthe filter screen
(2) and exits through the outlet
(3). The cleaning disc
(4)moves up and down inside the filter screen, repeatedly cleaning thescreen. Impurities are discharged from the bottom.
A Pneumatic Cylinder Scraper Filter is an automatic self-cleaning filtration system that uses a pneumatic cylinder to drive a scraper mechanism, removing accumulated solids from the filter surface without stopping the process.
During filtration, solids are retained on the filter element. When cleaning is triggered by pressure difference or timer, a pneumatic cylinder activates the scraper, which moves along the filter surface to remove debris. The waste is then discharged through a drain outlet.
Key advantages include stable automatic cleaning, precise control via compressed air, suitability for continuous operation, reduced manual maintenance, and strong performance in handling sticky or high-solid-content fluids.
These systems are widely used in chemical processing, petrochemicals, coatings and resins, oil refining, food and beverage, and wastewater treatment industries where continuous filtration and reliable cleaning are required.
Pneumatic scraper filters use compressed air-driven cylinders for precise and responsive cleaning control, while mechanical scraper filters rely on motors or gear systems. Pneumatic systems are often faster and more adaptable for automated processes.
