I. Description
The filter screen is a mesh-structured component with filtering function.
It is generally made of fiber materials (such as polyester fiber), metal wire mesh (such as stainless steel wire mesh), or a combination of both. The mesh size and shape of the filter screen vary. The mesh size can range from micron level to millimeter level, and the shapes include various forms such as square and round. Its size also has multiple choices depending on different application scenarios and can be installed in ventilation openings, air inlets, or pipelines of various devices.
The edges of the filter screen are usually reinforced, such as using rubber frames or metal frames to facilitate installation and ensure that the filter screen will not be easily deformed during use. Some filter screens will also undergo special coating treatments, such as anti-static coatings and anti-corrosion coatings, to enhance their performance.
II. Advantages
1. Filter impurities:
- It can effectively intercept particles such as dust, pollen, and hair in the air and prevent them from entering the equipment. For devices like air conditioners and air purifiers, the filter screen can ensure that the incoming air is cleaner, thereby improving the operating efficiency of the equipment and prolonging the service life of the equipment.
- In some places with high environmental requirements, such as laboratories and electronic production workshops, the filter screen can prevent tiny impurities from affecting experimental results or damaging precision electronic components.
2. Protect equipment:
- By filtering harmful impurities, the filter screen can reduce wear and corrosion of internal parts of the equipment caused by dust accumulation. For example, in computer server cabinets, the filter screen can prevent dust from entering the server and avoid server failures due to overheating.
- It can also prevent insects, foreign objects, etc. from entering the equipment to avoid physical damage or electrical short circuits.
3. Improve air quality:
- In ventilation systems, the filter screen can remove odors and harmful gases in the air (some filter screens have this function) and provide a healthier and more comfortable indoor environment.
- For some people with allergies, ventilation equipment equipped with high-efficiency filter screens can reduce the spread of allergens and reduce the occurrence probability of allergic reactions.
4. Easy to maintain and replace:
- The installation and removal of the filter screen are usually relatively simple. After the filter screen has been used for a period of time and accumulated a lot of impurities, users can easily remove it for cleaning or replace it with a new filter screen to restore the filtering function of the equipment in time.
- Moreover, the cost of the filter screen is relatively low, and regular replacement of the filter screen will not bring excessive economic burden. The cabinet 804 filter is usually a square thin sheet structure. Its size is designed according to the vent specification of cabinet 804 and can cover the vent well. The color is generally black or white, which is relatively coordinated with the overall color of the cabinet.
- The material is mainly fiber material or metal wire mesh. The fiber filter has a relatively soft texture and can effectively filter tiny particles such as dust and hair; the metal wire mesh filter is more sturdy and durable, and is more suitable in some environments with higher protection strength requirements.
- The size and shape of the mesh of the filter are carefully designed. The meshes are usually small holes evenly distributed. The size is generally between several tens of microns and several hundred microns. Such a size can block most dust, debris and other impurities from entering the cabinet, and at the same time will not cause too much obstruction to the ventilation effect of the cabinet.
