Stainless Steel Mesh Filter

Saifilter offers stainless steel mesh filters in 304 or 316L stainless steel. Stainless steel wire mesh filters are available in a variety of configurations, including Stainless Steel Filter Cartridges. Because the material properties of stainless steel mesh are more flexible, we can customize it in any shape according to the customer's specific application needs. For high-purity industrial filtration applications for special water treatment, Saifilter offers a wide range of apertures from 1-5 micron stainless steel mesh filters or 100 mesh filter screens.

Saifilter‘s wire mesh filter screens are suitable for various applications that require different aperture sizes. These stainless steel mesh filter cartridges can be combined with perforated metal or porous metal woven mesh for versatile configurations. Even in corrosive operating environments, the wire mesh filter screen can maintain its integrity and interception efficiency.

We offer single-layer or multi-layer combinations of stainless steel filter screens, aiming to meet various customer needs for filtration applications of different sizes. Standard weave options include plain, twill, and Dutch weave patterns.

Different customers have different requirements for manufacturing processes. These woven wire mesh filters can be manufactured by stamping, sintering, resistance welding, CNC, TIG welding, and micro-welding processes to meet customer needs. Whether it's a fine chemical process or a heavy industrial fluid application, our stainless steel mesh filters prevent chips, burrs, and wear particles from damaging your fluid system with long-lasting durability and particulate interception efficiency.

In the environment of various pumps, in order to prevent the pump from blocking or damaging the impeller, we specially designed the mesh filter screen for pump and the mesh filter screen for pipe. They can effectively intercept and remove impurities from liquid systems.

Woven Steel Wire Mesh

Woven steel wire mesh is a low-cost and highly efficient filtration medium, with a micrometer-level range between 1 and 2000 micrometers. Because parameters such as wire diameter, mesh count, and weaving pattern of woven wire mesh are fully customizable, it comes in PW (plain) and TW (twill) square weaves, as well as PDW (plain Dutch) and TDW (twilled Dutch) Dutch weaves.

Sintered Mesh

The sintered mesh made of woven wire mesh with different meshes by vacuum high-temperature firing has high mechanical strength and uniform pore size, and the micron scale ranges from 1 to 100 microns. Sintered wire mesh filter media provide absolute retention ratings across a wide range of degrees of filtration for liquids and gases.

Photo Etching Metal Filter

The filter medium of the photo etching metal filter has a smooth surface and a larger open area. The smooth surface reduces the flow resistance and pressure difference of the liquid, thus allowing the liquid to be filtered at a lower pressure difference. Easier cleaning and maintenance for the photo etching metal filter to intercept burrs and wear particles in the system.

Laminated Perforated Sheet Metal

Laminated perforated sheet metal filter media are sintered together with perforated sheet metal and multiple layers of woven steel wire mesh, which forms a very strong and easy-to-handle porous sheet. It has high-pressure resistance and high mechanical strength. Suitable for environments requiring fine filtration and high-pressure operation.

A stainless steel mesh filter is a filtration device made from tightly woven stainless steel wires. It is used to separate solids from liquids or gases by allowing the fluid to pass through while trapping particles on the surface of the mesh.

Stainless steel mesh filters find applications in various industries such as automotive, pharmaceuticals, food and beverage, oil and gas, and more. They are used in air and water purification, oil filtration, particle separation, and even in coffee machines.

Stainless steel mesh filters are highly durable due to the corrosion-resistant nature of stainless steel. They can withstand high temperatures, exposure to chemicals, and physical wear, making them suitable for demanding environments and prolonged use.

Yes, many stainless steel mesh filters can be cleaned and reused. They can be washed, soaked in cleaning solutions to remove trapped particles, and then rinsed for future use. Regular maintenance ensures optimal performance and longevity.

Stainless steel mesh filters offer several advantages, including high mechanical strength, resistance to corrosion and rust, ability to withstand extreme temperatures, fine particle filtration, and reusability. They provide a cost-effective, reliable, and environmentally friendly filtration solution.
