What are the types of primary filters? What is the difference between primary filter and precision filter maintenance? Primary filter is a very common filtration equipment, usually as an air conditioning system or purification system of the primary filtration equipment, able to filter the dust particles in the air with a particle size of more than 5 microns. Primary filters in the market are mainly non-woven fabric, synthetic fiber and glass fiber and other types. Synthetic fiber primary filter Synthetic fiber primary filter used in the filter material, is an emerging product, but also the main direction of the future development of filtration materials, this filter material and other materials of the same level, compared with the air resistance is small, light weight, dust capacity, etc., and is very environmentally friendly, can not be used after the incineration of the treatment. There are many synthetic fiber primary filters in the market, but the quality of the products of different manufacturers also vary, which use the filter material has a large chemical fiber and small chemical fiber points, large chemical fiber is...

What is the working principle of the primary effect filter? What are the performance indicators of the central air conditioning primary filter?

2022-07-06

What is the working principle of the primary effect filter? What are the performance indicators of the central air conditioning primary filter? First, the working principle of the primary filter The main working principle of the primary filter is that in the normal operation of the equipment, there is an air inlet at its forefront, it will be all the surrounding air inhalation, and then into the filter inside the first gate, the air filtration cylinder, it will initially remove all the large particles of solids in the air after clean. Then it will enter into its internal second gate - air filter filtration, after the exclusion of some large particles of solids, the air is once again purified, many of the fine particles, dust and bacteria, etc., all removed and filtered clean, in this way, you can ensure that the air into the cylinder is completely clean. Second, the internal maintenance of the preliminary filter 1, pre-filter maintenance (generally for the chassis back cover). Pre-filter to clean up 1-2 times a month...

What is the role and classification of the primary air filter? What are the points of attention for the installation of primary effect filter?

2022-07-04

What is the role and classification of the primary air filter? What are the points of attention for the installation of primary filter? As the primary filtration of air conditioning system, it mainly filters dust particles above 5μm. In the atmospheric dust counting method, the counting efficiency (%) is 20≤E＜80, and the plate type, folding type and bag type become three typical styles. It is used in the pre-filtration of air-conditioning and ventilation system to avoid the accumulation of dust and pollution inside the system; the role of the filter is important in the purification project air-conditioning system, while the primary filter is used in the pre-filtration of large-scale air compressors, the centralized ventilation and air-conditioning system of the clean room and the return air filtration to prolong the service life of the back-end high X filters; in fact, the primary filter is also used in the ventilation system of the common industrial plants to achieve the general cleanliness of air. The primary effect filter is also used in the ventilation system of general industrial factories to achieve the general clean air demand. Plate-type primary filters are widely used in office areas, shopping malls and buildings, scientific research institutions to play a huge role, but also in the pharmaceutical, food, precision electronics industry as a centralized ventilation...

What is the difference between primary, intermediate and high efficiency filters? What is the replacement cycle of air filters?

2022-06-27

What is the difference between primary, intermediate and high efficiency filters? How long is the replacement cycle of air filters? The main difference between the primary filter, medium and high efficiency filters lies in the filtration efficiency and the different uses, functions, materials, speed, different filters, the function may be a little different, in the multi-stage filtration system using both the primary and secondary filters and high efficiency filters, the primary filter is designed to alleviate the filtration pressure of the medium efficiency filter, while the primary filter, the medium efficiency filter is designed to alleviate the pressure of high efficiency filters and improve the service life of high efficiency filters, because, the price of the high efficiency filter is far more expensive. Improve the service life of high-efficiency filters and set up, because the price of high-efficiency filters is much higher than the primary and intermediate filters. Here we take a look at the primary filter, intermediate filter, high-efficiency filter features and replacement cycle: Primary filter: the primary filter of the air conditioning system, mainly used for filtration of dust particles more than 5 μ m, the primary filter has a plate, folding type, bag type three.
