The air filter is a device that collects dust from the gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It sends the air with low dust content into the room after purification to ensure the process requirements of the clean room and the air cleanliness of the general air-conditioned room. so air filter brand: what are the classification of air filter?
air filter brand: what are the classification of air filter?
1. Coarse filter
The filter material of the coarse filter is generally non-woven fabric, metal wire mesh, glass fiber, nylon mesh, etc. Its structural forms are plate type, folding type, belt type and winding type.
2. Medium effect filter
Commonly used in-effect filters are: M-I, II, IV foam filter, YB glass fiber filter, etc. The filter material of the medium-efficiency filter mainly includes glass fiber, mesoporous polyethylene foam and synthetic fiber mat made of polyester, polypropylene and acrylic fibers.
3. High efficiency filter
Commonly used high efficiency filter has national standard and GWB. The filter material is a superfine glass fiber filter paper with very small pores. With a low filtration rate, the screening and diffusion of fine dust particles are enhanced, so the filtration efficiency is high.
Air filter brand: What is the role of air filter?
The design of the filter itself has also made significant progress, the more important of which is to remove the partition, that is, to develop a filter without a partition. The non-clapboard filter not only eliminates the danger of the partition damaging the filter medium, but also effectively increases the filter area, improves the over-vibration efficiency, reduces the airflow resistance, and reduces the energy consumption. In addition, the air filter in high temperature resistance, corrosion resistance, waterproof, antibacterial and other aspects have also made great progress, to meet some special requirements.
Air filter brand: What is the main performance of the air filter?
1. It refers to the maximum diameter of foreign particles allowed. The key factor affecting the filtration accuracy is the filter element. Different filter elements can be selected according to the requirements of the following components to achieve the corresponding filtration accuracy.
2. Flow characteristics refer to the relationship curve between the air flow through the filter and the pressure drop at both ends of the filter under a certain inlet pressure. In actual use, it is recommended to choose within the range of pressure loss less than 0.03MPa. In the air filter, the main factors affecting the flow characteristics are the body and the filter element.
3. It refers to the ratio of separated water to the water contained in the air inlet. Generally, the water diversion efficiency of the air filter is not less than 80%, and the main factor affecting the water diversion efficiency is the deflector.
4. The purpose is to obtain clean air that can meet the standards. General ventilation filters capture and absorb dust particles of different sizes in the air, thereby improving air quality. Chemical filters can mainly absorb odors other than dust, and are usually used in biopharmaceuticals, hospitals, airport terminals, human settlements and other places. General ventilation filters are widely used in microelectronics, coating, food and beverage industries.
All in all, air filters are mainly used to remove mechanical impurities in the air, such as dust and dust.
