Air filter is a kind of air filtration device, the main function of this device is to be able to make the indoor environment to maintain in the range of always wanted. There are five main types of air filters on the market, and different types of air filters have different standards and methods of use. Air filters can be used in a variety of occasions. The following Xiao Xiao will give you an introduction to the price of air filters on the market, as well as air filters have what kind of role, as well as the classification of air filters.
Price of air filters
The price of air filters is 34 dollars to 410 dollars. (Prices are from the internet and are for reference only.)
The role of the air filter
The compressed air coming out of the air source contains excessive water vapor and oil droplets, as well as solid impurities, such as rust, sand, pipeline sealant, etc. These will damage the piston sealing ring, blocking the small vent holes on the components, shortening the service life of the components or making them fail. The role of the air filter is to separate the liquid water and liquid oil droplets in the compressed air, and filter out the dust and solid impurities in the air, but can not remove the gaseous water and oil.
Classification of air filters
Air filters
Air filters
are often made of man-made fiber filter material, and the outer frame is made of strong, moisture-proof hard paper frame. It will not be deformed, cracked or twisted under normal operating conditions. This? The filter media is fixed diagonally before and after the outer frame. The filter media and the outer frame are tightly bonded to the outer frame to prevent air leakage.
Medium Efficiency Air Filter
Made of a combination of synthetic fibers and galvanized iron. Various efficiencies are available, including ?40-45%? ,?60-65%? , ?80-85%? ,?90-95%. The flange consists of 26 gauge galvanized iron. This series of products can be used in industrial, commercial, hospitals, schools, buildings and other factories air conditioning equipment (the primary filtration of the air conditioning system to protect the next level of filters in the system and the system itself, in the air purification and cleanliness requirements are not strict, the air can be sent directly to the user after the treatment of intermediate filters), but also can be installed in the gas turbine air inlet equipment or computer room, in order to prolong the equipment The service life of the equipment can be extended.
Primary filters
Mainly applicable to primary filtration of air conditioning and ventilation systems, clean room return air filtration, pre-filtration of local high-efficiency filtration devices, mainly used for filtering dust particles with particle sizes of 5 μm and above, using the gravimetric method of testing. It is also used for the primary protection of multi-stage filtration system. Filter materials include non-woven fabrics, nylon mesh, aluminum wave mesh, stainless steel mesh, etc. The non-woven filter media outlet surface is lightened to prevent the non-woven fibers from breaking and flying apart and causing secondary pollution.
DC, DZ-type coarse and medium-effect bag filter
Adopting primary and medium-effect nonwoven fabric as filter material and cold plate spraying as frame, it is used as the first and second stage filtration, which has the advantages of large dust holding capacity, small resistance and washable, etc. According to the use of different environments and materials, the efficiency level of its filters is classified into F5, F6, F7 and F8.
High-efficiency air filter
Applicable to air filtration at room temperature and humidity, allowing the presence of trace acids, alkalis and organic solvents, the product has high efficiency, but high resistance and small dust holding capacity, and is widely used in aerospace, aviation, electronics, pharmaceuticals, biological engineering and other precision fields.
Used to filter out dust impurities in the air inhaled by the compressor, the cleaner the air inhaled, the oil filter element, oil and gas separation core and the oil service life of the more secure; to prevent other foreign objects into the host, the host caused damage to the host, resulting in the host "hold" or even scrapped. The life expectancy is usually about 2000 hours.
High-efficiency air filter product classification: high efficiency filter with partition, high efficiency filter without partition, V-BED high efficiency filter, high temperature resistant high efficiency filter.

How much is the price of the air filter, and what are the recommended manufacturers of air filters, as well as what kind of air filters, air filters, air filters, what are the main classifications, which have been in the above article to give a detailed introduction to you. Air filter is a very good air filtration device, in many places have to use, not only in the hospital have to use some of the environmental requirements of the processing plant, but also the installation of air filters.
