Stainless steel filters are widely used in metallurgy, chemical, petroleum, paper, pharmaceutical, food, mining, electricity, urban water supply area. Such as industrial wastewater, recycled water filtration, emulsion regeneration, oil filtering, the metallurgical industry of casting water systems, blast furnace water systems, hot-rolled high-pressure water descaling system. Is an advanced, efficient and easy to use automatic filter. The filter is simplified, stainless steel strainer, sewage parts, transmission and electrical control components. 
 Filter work, to be filtered into the water from the outlet when, through the filter, the user must enter through the export pipeline to process cycle, the water particles are trapped in the filter inside acrobatics. This continuous cycle is retained down more and more particles, the filtration rate became slower, while imports remained steady flow of sewage entering the filter holes will become increasingly smaller, resulting in the inlet and outlet pressure between poor, when the difference reaches the set value of generosity, the differential pressure transmitter to send signals to the controller, start the drive motor control crying driven by a drive shaft rotating components, while open sewage outfall from the sewage outfall discharge, when After filter cleaning, pressure dropped to the minimum, the system returns to the initial filter state, the system running.
