904l ss filter mesh

Types of 904L filter meshes

The stainless steel mesh is a woven filter that provides high flow rates and excellent filtration. 904L ss filter meshes are used to separate solid particles from gas or liquid. They can be used as a preseparator to avoid clogging the next filter element. They can be used to separate bacteria in the food and beverage industry or to filter air in a cleanroom environment. Here are some types of 904L filter meshes.

• Textile filters: The textile filter mesh is made of high-strength polyester, polypropylene, and other synthetic fibers. These filter meshes are not easily deformed and have long service lives. Filter bags made of these filter meshes can capture more harmful dust particles, such as cement dust, carbon black dust, etc. However, textile filters cannot separate toxins or bacteria.
• Paper filters: Paper filter meshes are often mixed with other dry filters, prefilters, and line filters. They are used as air filter elements in extracting equipment and modules. The replacement filter is usually made of FDA-compliant paper to meet food-grade requirements. Paper filters can separate bacteria, so they are often used in the oil and beverage industries.
• Woven wire filters: Woven wire 904L ss filter meshes have uniform holes. Woven wire filters can provide consistent filtration. Woven wire meshes can withstand harsh chemical environments and high temperatures. The large openings make them ideal for filtering large particles. They are often used as strainer elements, disc filters, basket filters, and inline pipe filters. To achieve desired filtration, suppliers can change the weave style, diameter of the wire, and opening size.
• Sintered filters: These filters are made from welding stainless steel powders together. They are commonly used in the oil and chemical industries because they offer more excellent chemical resistance and higher porosity. The porosity of a sintered filter mesh is much higher than that of a woven filter mesh, making it more efficient at filtering small particles. In addition, woven wire 904L ss filter meshes can be cleaned and reused. However, sintered filters are usually disposable.

Specification and maintenance of 904L ss filter mesh

The wire used for 904L mesh filters has a diameter of around 0.20 mm but may vary according to the specific application. The opening size is the size between the wires. It is often called the 'aperture'. An aperture size of 0.45 mm is very common. Other sizes vary between 0.1 mm and 1.0 mm. The usual roll width is around 0.91 mm, but filter mesh can also be made in widths between 0.45 mm and 1.2 mm. The length of 904L mesh filter rolls can be as much as 150 m. Standard specification for mesh filters is as follows:

• Product: 904L Filter Mesh
• Gauge (mm): 0.2
• Aperture (mm): 0.45
• Roll Width (m): 0.91
• Length (m): 50

Moreover, various other specifications are also possible. 904L stainless steel filters are usually manufactured using a continuous weaving process, which results in wire mesh with finer openings and is exclusively made for filtering.

Maintenance:

The mesh filter can be cleaned easily by rubbing it with bar soap that is neutral when doing ordinary cleaning. But when the mesh filter is regularly exposed to petroleum products, hard water, or chemicals, the filters must be cleaned thoroughly and occasionally, which should also be done in normal use.

• Clean chemical: A mild organic solvent, such as isopropyl alcohol or acetone, may assist in the removal of impurities or contaminants. Additionally, before filtering, highly recommended solvents include toluene, THF, and acetonitrile. It is important to utilize a significant amount of suggested cleaning agents to ensure that the mesh is being soaked completely.
• Method: The cleaning process can be carried out via submersion or spraying. It is necessary to ensure that the surface of the filter is adequately cleaned when spraying the substance onto the filter. Utilizing a non-solvent cleaning method can improve the filter's life.
• Non-solvent cleaning: The 904 stainless steel filter can be cleaned with pressurized water whenever feasible. If the mesh filter is not extensively dirty and only water is available for cleaning, this approach should be utilized. Applying high pressure from water pipes or wash guns can remove particulate matter from filters.
• Regular cleaning: The 904 stainless steel mesh filter should be cleaned before its replacement to prevent the accumulation of contaminants and impurities. Preventing the build-up of dirt on the filter will help to prolong its life span.
