What is a Wire Mesh Filter?

A wire mesh filter is a device made of interwoven wire strands that is used to separate, sieve, or filter a variety of materials. The wire mesh can be made from various materials, such as stainless steel, brass, or other metals, and the size of the mesh can be tailored to suit the specific filtering application.

Wire mesh filters are commonly used in a variety of industries and applications, including air and fluid filtration, chemical processing, food and beverage processing, and oil and gas production. They are often used to remove contaminants or impurities from liquids or gases, or to separate larger particles from smaller ones.

Wire mesh filters are known for their durability and reliability, and they can be used in a wide range of operating conditions. They are also easy to clean and maintain, and can be used repeatedly without requiring replacement.

We work in conjunction with the customer to meet their needs. Whether the customer needs a simple standard mesh filter or a complex custom mesh filter, we help design and manufacture their optimal filter.

We’re here to make your custom wire mesh filter.

The Roles of Wire Mesh Filters

Wire Mesh Filters For Fluid Rectification

Liquids flowing through pipes are often turbulent. A wire mesh filter can rectify this turbulent flow and ensure that the flow of the fluid steadily and efficiently reaches its destination. Wire mesh filters may also silence noise associated with this flow.

Wire Mesh Filter Clogging Counter Measures

Often times unwanted particles and objects can flow through pipes and without any sort of wire mesh filter this can lead to the pipe becoming clogged. To combat this, a wire mesh filter is press-fitted in the direction opposite of the flow. Our wire mesh filters are designed with large filtration areas and reinforced wire mesh to ensure that the filter does not get damaged under the pressure of being against the flow.

Collection of Foreign Substances

Wire mesh filters can be fitted in the direction of flow inside the pipe. This leads to foreign substances being both stopped and collected by the filter, protecting the pipe’s destination from being exposed to unwanted materials.                        

Wire Mesh Filters for Gas and Liquid Separation

The gas and liquid in refrigerants can be separated during the mist state using a special filter, such as an accumulator filter. Droplets of water collect on the wire mesh, eventually falling down. Only the gas is able to pass through the filter. The liquid refrigerant, which has been accumulating at the bottom, eventually evaporates and becomes gas, starting the next cycle of separation.

The Main Roles of Wire Mesh Filters

1. Foreign Material Removal Collects foreign matter such as dust, sand, dirt, and other various scraps flowing through the pipes.
Increases machine performance, improves efficiency, and extends the machine’s lifespan.
2. Flow Turbulence CorrectionRectifies turbulent flow of liquid within the pipe
Controls the flow rate, mitigates sudden changes in pressure, and reduces noise.
3. Gas Liquid SeparationAs the name implies it separates gas from liquid.
Liquid particles are removed, and only gas is able to pass through the filter.

Creation and Features of Wire Mesh Filters

Mesh Weaving Process

Mesh is woven employing the same methods as traditional textiles. Metal wires are woven together to create a metallic mesh screen. For metal mesh molding (especially the blank and draw process) this is suitable for mass production. Woven mesh also has a cheaper unit price than etched mesh, leading to a cheaper overall filter.
In addition, the strength and size of the mesh can be adjusted according to how the mesh is folded. Therefore woven mesh can accommodate a wide arrange of needs. Iron wires are welded together to create sintered mesh, which prevents frayed wires and misalignment from occurring. Multiple mesh screens are stacked to achieve high filtration performance and excellent pressure resistance levels.

Etching Process

Etching is a method of making holes in a thin metal plate, such as stainless steel, by corroding it with an etching solution (i.e ferric chloride). The original plate cost is low, and it is fine for a small order quantity. However, the manufacturing unit price is higher than that of woven mesh processing, make it less optimal for a large order. Since the filter has been etched instead of woven, it does not have issues with fraying, burrs, or misalignment.

Perforated Metal

Perforated metal is created via metal punching. Metal punching is the process of punching holes out of a plate shaped object. A relatively large hole can be punched out, with a hole diameter of 0.5 mm or more and a pitch of 1.0 mm or more. Since a general-purpose mold is used, it can be manufactured for a relatively low cost. However, this method is not ideal for manufacturing filters with small wire diameters.

Applications of Wire Mesh Filters

Our mesh filters are used in over 60% of Japanese air conditioners. In addition to this, our filters are used in automobile engines, car air conditioners, refrigerators, washing machines, gas stoves, gas burners, water heaters, EcoCute systems, vending machines, elevators, water faucets, purification devices, and countless other machines.
The demand for mesh filters for use in next-generation vehicles such as fuel cell vehicles and electric vehicles, hydrogen station dispensers, and aerospace is expanding infinitely. 
Vantech is making use of its abundance of experience and technical know-how to break into emerging industries. Vantech will contribute to the development of next generation products to keep up with the changing times.
