Filter Gate

Product overview
Product specifications
Size200A ~ 1,000A
  • Adjustable filter mesh specifications to suit on-site needs
  • Separate consultation required for 1,100A or more
Product Use Various water and sewage facilities requiring filtration
Product Features
  • This is a specialized device designed to improve the social issue of finding living larvae or undead bodies of various flying insects in ordinary households in 2020. It blocks larvae and various foreign substances generated during the tap water production process, enabling the supply of clean water to households.
  • It is installed in the pipeline of a water purification plant or reservoir in connection with an existing water treatment facility without separate auxiliary equipment, and is an easy-to-maintain product that can be easily attached and detached by mounting a filter with a pore size of 100㎛ or less made of STS material on the disk.

Stud Bolt & Nut
  • Role in enabling strong compression of gland packing
Gate
  • Structure that enables easy removal of the filter module
Filter module
  • Available in two types of structures: pleated and flat, it can be manufactured to meet various requirements depending on the installation environment.
Nozzle Gear & Moter Ass'y
  • Filter wash by spraying high-pressure washing water of 5 bar or more from a spray nozzle
Rotary Nozzle
  • Filter cleaning by rotating and spraying at a constant speed using a rotary nozzle
Drain Pipe
  • Discharge of foreign substances and washing water
Shaft
  • The main body has a screw structure and transmits the power of the motor to the gate, helping the gate move up and down.
Bonnet
  • The role of supporting the fixation of the motor and the up and down operation of the gate
Actuator
  • Generates the power to move the gate up and down
Filter Module

    Rib
     
      Role in preventing mesh damage caused
      by sludge in the fluid.
    Main
    Mesh
      Made of stainless steel with excellent corrosion resistance, it is capable of precision filtration, and mesh specifications can be custom-made according to on-site conditions.
      Assistance
      Mesh
        The role is to protect the main mesh by preferentially filtering out large particles of foreign matter.
      Packing
        A sealing function to prevent larvae and foreign substances from passing through the gaps of the assembly using rubber material for water supply.
      Pleated filter features
      • WIRE filters inevitably suffer from flow loss due to wire diameter, so expansion work is required depending on the site.
      • It is a seamless, one-piece material, and can compensate for 100% of the flow loss due to the cross-sectional area being expanded by approximately 2.4 times compared to a flat filter.
      • Installation space, cost, and period can be reduced as expansion work is not required.
      Filter Cleaning technology
        ① ​Multiple fan-shaped nozzles with excellent spray concentration spray close to the filter to improve cleaning efficiency, and the nozzles can be rotated to clean the entire filter area.  
        ② ​A structure that detects the degree of blockage of the filter through pressure difference or water level difference, and automatically cleans by spraying high-pressure washing water of 5 bar or more from the spray nozzle when the gate is deployed.
        ③ ​Before the gate, a structure that blocks leakage of some fluids ejected from inside during the closing operation through a water-tight member-containing water barrier plate and discharges washing water and washing foreign substances into a drain.
      An example of the filter gate installation process
        ① ​The distance between the sides of the product is shorter, ensuring less restriction in the installation space.
        ② ​When replacing the filter, there is a limit in the height for raising the gate, but the height limit can be supplemented by installing an optional inner screw.
        ③ ​When replacing the filter, the filter must be replaced after closing the valves at the front and rear of the filter gate to completely block foreign matters.
