The S-series self-cleaning filter is a fully automatic self-cleaning water filter. A set of brushes is installed in the filter mesh barrel, and the brushes are driven by a motor to rotate. An electric drain valve is installed on the filter end cover. During operation, turbid water enters the filter cartridge through the water inlet and filters the dirt through a stainless steel wedge mesh. Purified water flows out from the water outlet. When too much dirt accumulates on the surface of the filter screen, the filtered water is impeded, and the pressure in the inner chamber of the filter cartridge rises. When the pressure difference between the inlet and outlet water reaches a certain value (preset), the differential pressure switch sends a signal to the controller. The controller starts the reducer motor to drive the brush to rotate to remove dirt and impurities from the surface of the filter screen. At the same time, open the electric drain valve to discharge the dirt, and the cleaning time is 20-120 seconds (can be set locally). During cleaning, there is no need to cut off the flow, the blowdown pressure loss does not exceed 0.5 bar, and the flow loss does not exceed 1%.
Model description Example S T M Y-200/10 S represents brush cleaning, T represents vertical installation, M represents horizontal installation, Y represents online installation, 200 inlet and outlet diameters, and 10 represents nominal pressure.
control system Adopt industrial single chip PLC automatic control, Chinese or English display. The filter can be automatically cleaned according to pressure difference or timing control, and can be manually or forcibly cleaned. Filtration time and cleaning time can be set on site. Operation signal, cleaning signal, fault signal output, and 485 communication interface.

Scope of application 1. Cooling water treatment - water filtration for cooling towers, make-up water systems, air conditioning systems, and once-through systems to reduce the generation of sediment in heat exchangers and maintain their cooling effect. 2. Raw water treatment - It can filter surface river water, lake water, seawater, reservoir water, well water, and groundwater to remove sand, bacteria, algae, organic matter, and so on. 3. Filtration of industrial circulating water - it can be used on equipment with certain requirements for water quality, such as cooling tower, rolling mill, continuous caster, polishing, water pump, solenoid valve, ion exchanger, spray, heat exchanger, etc., or water supply and drainage pipelines to filter out impurities in water and avoid blockage of pipes, nozzles and other parts. 4. Irrigation - Especially suitable for water sources with high flow and high impurity content, agricultural irrigation, sprinkler irrigation, parks, golf courses, turf irrigation, etc. 5. Paper industry - white water filtration. 6. Plastics industry - injection molding cooling circulating water filtration. 7. Membrane pretreatment, resin pretreatment, ultrafiltration pretreatment. 8. Seawater desalination pre-treatment filtration, aquaculture filtration
