  • Product Description

    Double filter is also called double switch filter. It is composed of two stainless steel filters in parallel. It has many advantages such as novel and reasonable structure, good sealing performance, strong flow capacity, easy operation, etc. It can accurately ensure the filtration accuracy, and can quickly replace the filter bag, and filter basically no material. consumption, which reduces operating costs.

    INQUIRY
    Applications filter hydraulic oil, lubricating oil, etc.; industrial quenching oil cooling system; RO security filtration, seawater desalination pretreatment, etc.
    Filtration media water suspended solids, particulate matter, water fouling, bacteria and algae, rust, etc.
  • Working Principle

    The Duplex filter is composed of two single cartridge filters and a full diameter three-way ball valve, with a simple structure and easy to use, in order to ensure the safety of the system. In the working process, when the single cartridge filter element is blocked to a certain extent and needs to be cleaned or replaced, the work of the main machine has to be stopped to replace the cartridge, which not only wastes time but also cannot meet the needs of continuous work of the main machine. His work is characterised by the fact that when a filter element is blocked and needs to be replaced, it is not necessary to stop the work of the main machine, as long as the three-way ball valve is switched to another filter, the other filter can participate in the work, and then the blocked element is replaced, and the filter cartridge on the side of the element needs to be replaced, allowing a small amount of leakage.

  • Product Advantages

    • Two three-way ball valves are used to assemble two single cartridge filters on a single seat, so that cleaning the filters does not have to be stopped.

      Operation

      Easy to install:

      Novel structure, easy and flexible operation, energy saving, high efficiency, airtight operation, smooth operation.

    • The double cartridge switching filter is composed of two single cartridge filters and full diameter three-way ball valve, simple structure, easy to use, in order to ensure the safety of the system.

      Structure

      Simple structure:

      Inside the filter is a metal mesh basket supporting the cartridge/filter bag, the liquid flows in through the inlet and out through the outlet after being filtered by the cartridge, impurities are intercepted in the cartridge and can continue to be used after replacing the cartridge.

    • Selection of excellent materials.

      Materials

      Made of excellent materials:

      The double cartridge switching filter is made up of two single cartridge filters and a full diameter three-way ball valve. It is simple in structure and easy to use in order to ensure the safety of the system.

    • The equipment is easy to use.

      Convenience

      The equipment is easy to use:

      When a filter element is blocked and needs to be replaced, just switch the three-way ball valve to another filter, the other filter can participate in the work, and then replace the blocked element, the filter cartridge on the side of the element needs to be replaced, allowing a small amount of leakage.
