3. What are Sintered Filters Used For ? 

Sintered filters have been designed and applied as a new fine filtration material for the food, beverage,

water treatment, dust removal, pharmaceutical, and polymer industries because of the excellent

performance of sintered filters, including the high mechanical strength of sintered filters and the wide

range of filtration grades.


4. How does Sinered Filter Disc Work ? 

   In brief, the production process of sintered filters consists of 2 steps
   1. Shaping
   2. Sintering

   However, before shaping and sintering, we must confirm with the customer the design, size, porosity,

    sintering melt filter process picture


5. What Kind of Stainless Steel is main used for Filter Disc ?  

The key grades of stainless steel powder appropriate for the production of stainless steel type of

 sintered filter disc comprise:

1.) Stainless steel 316, comprised of manganese, silicon, carbon,nickel and chromium elements.

    food grades for many applications included Food and Food and medical filtration etc

3.) Stainless steel 304, Constitutes nickel and chromium metals that are non-ferrous elements.

4.) Stainless steel 304L, Has a higher quantity of carbon content in comparison to stainless steel 304.

    sure the price will be lower than 316L, 316, etc


6. How do you Clean Stainless Steel Wire Mesh Filter Disc? 

   There are several methods of cleaning stainless steel filter discs, with the choice of each method

   depending on your type and level of operation.

   Let’s look at some of the common methods of how to clean metal filter discs.

    1) Blowback and Backwash Flushing

    It is one of the simplest methods of cleaning filter discs.

    For backwash flushing to work successfully, it depends on the reverse flow of fluid to dislodge

    and carry particles away from the media structure.

    The fluid used is normally filtrated or another process-compatible fluid.

     The blowback and backwashing technique relies on loose attachment of the particles on or

     within the holes of the filter mesh.

     Using gas as the pressure source instead of liquid generates much turbulence as the generated

      pressure forces the gas/liquid mixture through the filter disc mesh.

 how to clean sintered filter disc

     2) Soak and Flush

    Cleaning stainless steel filter discs refer to using a detergent solution.

     In this technique, you allow the filter disc to soak adequately for the action of the detergent to

     loosen particles and flush them out of the filter media.

     In a laboratory, you can carry out this procedure in processing stainless steel filter discs or with small



     3) Circulation Flows

    In this method of cleaning the wire mesh filter disc, you need a cleaning system to help pump and

    circulate a cleaning solution across the filter mesh until it is clean.

    The circulation is usually in the opposite direction from which the filter disc mesh was soiled.

    You must filter the cleaning solution before returning it to the filter media.


    4) Ultrasonic Baths

    This technique requires special equipment that employs ultrasonic sound waves to trigger off

     particles and remove them from the filter mesh.

    You can use laboratory models of this equipment to easily clean small stainless steel filter discs,

    whereas bigger ones need big tank equipment with high power inputs.

    Ultrasonic cleaning, in conjunction with the right detergent solution, is the most efficient method of

    cleaning filter discs, particularly in the case of deeply embedded particles.


     5) Furnace Cleaning

    It is also a simple technique of cleaning metallic filter discs by volatilizing or burning biological or

    organic compounds. It is most effective for removing polymer materials.

    Furnace stainless steel filter disc cleaning is suitable for substances that leave no residual ash.

    Otherwise, you will need an additional cleaning method to remove the ash residue.


     6) Hydro Blasting

    Hydro blasting cleaning techniques usually supersede other cleaning techniques when the particles

     have grossly obstructed the holes of the filter mesh.

     You can employ this method to clean, for example, filter discs in cross-flow tubes.

     The high-pressure water jet removes the trapped particles through high-energy impaction.

     It does not go very deeply into the filter mesh; however, in most instances, the obstruction may be only

      at the filter media surface.

     It is commonly applied in plants, and usually used to clean heat exchanger tubes.


7. Which Factors should you Consider when Choosing Stainless Steel Filter Disc?

     When Selecting the right sintered metal filter disc to ensure the efficiency of your filtration system,

     therefore, you should consider the following factors when choosing a stainless steel filter disc:

  • Type of Filter Media

         There are different filter media types, such as random metal fiber, photo-etched, and sintered

         filtration media, each with its advantages and disadvantages.

          Therefore, you must choose a stainless filter disc with the right filtration media for your applications.


  • Type of Stainless-Steel Used

         Stainless steel comes in various kinds, with each type having advantages that are fit for different purposes.

         Before buying one, it is crucial to ascertain the individual characteristics of the material used to make a filter disc.

         Such characteristics include pressure, temperature limits, and reactions to other compounds and conditions.


  • Mesh Number

        It is the number of holes per inch of a stainless steel filter mesh.

        If the mesh number is big, it indicates numerous holes per inch of the filter disc mesh.

        It also signifies that the individual holes are small and vice versa.


  • Mesh Size

        The mesh size designates the size of individual holes on the stainless steel filter disc mesh.

        It is always measured in millimeters, microns, or fractional inches.


  • Strand Diameter

         It is a crucial consideration when selecting a stainless steel filter disc.

         When a wire has a broad strand diameter, it signifies that it has tiny mesh holes.


In short, the larger the strand's diameter, the greater the mesh number of the sintered filter disc.

The diameter of the strand is a percentage of the overall surface area of the stainless steel filter mesh, i.e.,

 the percentage of open area. Therefore, having a greater percentage of the open area indicates

that the filter disc has a high flow.

  • Filament Diameter

This parameter affects the mesh openings and the percentage of the open area of the filter mesh.

  • Fluid Compatibility

You should ensure that the stainless steel filter disc is well-matched with the fluid you want to filter.

It helps avoid any reaction between the filter disc and the fluid involved since any reaction will

negatively impact the quality of the filtration process.


8. ls there Shape Limitation for Stainless Steel Wire Mesh Filter Disc?

     No, you can design as your project requires.  share your size, pore size, flow control etc and 

contact us for details.


9. What Are the Advantages of Sintered Filter Discs?

Four Main Advantages Include: 

     1.) Durability
