Nowadays, people realize that the air conditioning system itself needs a good filter to protect. What impacts bring to the air conditioning system only with low efficiency filters? The airway is blocked, the fan fouling makes the air volume; the heat transfer component is reduced; the temperature and humidity and other measurement and control components failing dynamic end blowing device failure full heat exchange device failure pipeline internal temperature and humidity is a microbial breeding Ideal places in many central air conditioners, using two years later, the performance has declined significantly, open the air conditioner, and the crux is clear.
In 1963, the United States had a clean room federal standard Fed STD 209. In 209 standards, the clean room is divided into several levels per cubic feet in the environment, such as level 100, 10,000, 100,000. China's past cleansing room standards are also graded in this way. In 1999, the International Standardization ISO issued the ISO14644-1 \"clean room and controlled clean environment, the first part: Air cleanliness.\" In 1999, the International Standardization ISO issued the ISO14644-1 \"clean room and controlled clean environment, the first part: Air cleanliness.\" The ISO specified in the cleanliness level and the specific numerical value of traditional grading are shown in the table below.
Metal mesh filter is also known as a metal hole net filter, the filter element is commonly used in multilayer corrugated aluminum mesh or stainless steel mesh, aluminum mesh or stainless steel network is transferred to a wavy shape, with the correct angle cross-overlay arrangement, air passes filter Multiple changes in the flow direction during the material; and arrange the low resistance of the gas stream by different densities, the aperture is reached, and the low resistance to the airflow is achieved, and its dust-proof ability and efficiency are increased. Metal mesh filter, safety, rugged, high temperature resistance, easy to clean and maintain, long-term use of the cost of use of overall air filters. The metal mesh filter has the following characteristics: 1, low resistance, long service life. 2, multi-hierarchical structure, increasing the filter area. 3. The full metal air filter material is made of multi-hierarchical cross-crossing wave type aluminum network, easy to clean and maintenance, can reach 100% relative humidity moisture resistance. 4, high temperature resistance to 250 ° C. 5, metal mesh filter wave type aluminum mesh hole from outside
When purchasing custom air filters, the requirements of the air filter, the European standard, the Europeani, the US standard, and it is easy to confuse, and the Shandong Xinli Xiaobian is organized, and the national standard grade standards for air filters. . The air filter is different from the filtering efficiency, which is generally divided into: initial (coarse), generic, high-efficiency, sub-efficiency, efficient, super efficiency air filter, the following introduces my country, Europe, the United States three countries Level division criteria for air filters. 1. China is different according to the filtering efficiency, my country's national standards divide the air filter into a coarse air filter, a high-efficiency air filter, a high-efficiency air filter, a high-efficiency air filter, a high-efficiency air filter, super efficiency air filtering . National standard \"air filter\" GB / T 14295-2019 (2020-05-01)
The type of air filter has a lot of filtering characteristics, field of use are not the same, what filters are PTFE efficient? His characteristics and application areas in which? First, PTFE is polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), a tetrafluoroethylene monomer as the polymerization of the polymer. White, waxy, translucent, heat resistance, good cold resistance, long-term use -180 ~ 260ºC. This material has acid alkali, resistance characteristics of various organic solvents, almost insoluble in all solvents. Also, polytetrafluoroethylene having high temperature characteristics, its low coefficient of friction. Efficient and PTFE / ULPA filter is a high efficiency particulate air filter made of PTFE film. He has a high filtration efficiency, low pressure loss, high dust holding capacity, tough paper, good sealing, compact structure, easy installation, resistance
