  • Product Description

    The automatic backwashing filter is mainly composed of a cartridge, a stainless steel screen, an electric drainage valve and a drainage device. When the water filter is in operation, the backwashing butterfly valve plate is opened and the water enters the filter cartridge from the inlet and flows out of the system after being filtered by the screen, impurities are intercepted inside the cartridge. When the water processor needs to be discharged, the butterfly valve plate is closed and the drain valve is opened. The water flows into the inner side through the outer half of the rear section of the screen and is filtered through the first half of the section, part of the water flows into the system from the outlet and the remaining water flows into the inner side from the outer half of the rear section of the screen and is discharged through the drain outlet, playing the role of reverse automatic flushing of the screen.

    Applications heating systems for heating, hot water circulation systems for heating; cooling and chilling water circulation systems for central air conditioners, chillers and refrigerators; industrial and civil cooling water, industrial cooling water circulation systems; circulation systems for bathing and heating using geothermal water.
    Filtration media Removal of various sticky substances, gum particles, silt and other mechanical impurities from water.
  • Working Principle

    Under normal circumstances, the steering valve is opened and the water is filtered through the filter cartridge and discharged from the outlet, when the drain valve station is opened, the total flow of liquid through the filter increases, the flow rate increases, impurities that stick to the wall of the filter are flushed, impurities are discharged from the drainage outlet, when the steering valve is closed and the drainage valve is opened, the water is forced to enter the outside of the filter cartridge from the inlet section mesh of the filter cartridge, most of it flows out from the outlet, and part of it enters the inside of the filter cartridge from the outside of the filter through the mesh of the impurity collection section, which produces a backwash to the filter cartridge and achieves the effect of flushing the impurities that stick to the mesh from the outside of the filter cartridge, impurities are still discharged through the drainage outlet.
