What are the advantages of the design of the material used for primary air filters?

The core equipment of the air conditioning purification system is the air filter What exactly is the role of the primary filter? Few people know that there are certain specifications on the filter, other impurities are filtered out when passing through this filter, thus enabling people to breathe healthy air. primary air filter is a common one in daily use, what are the characteristics in operation and what role can it play?

Primary air filter design and production characteristics:

1. Filtration of dust particles of 5um and above particle size;

2. Frame: aluminum alloy, galvanized sheet, paper frame, stainless steel, thickness: 17mm, 21mm, 25mm, 46mm, and other models;

3. Filter media: high-quality chemical fiber non-woven filter media, with high air volume, low resistance, and high dust capacity;

4. The use of surface rust-proof treatment wire mesh, which can be well fixed to protect the filter material in use is not easy to damage;

Plate primary filter is the alias of the primary filter, general application: air conditioning and ventilation system pre-filtration/clean room return air filtration/pre-filtration of local high-efficiency filtration device.

The primary air filter forms a resistance to the air. As the dust accumulation in the filter increases, the filter resistance will increase. When the filter accumulates too much dust and the resistance is too high, the filter will pass through a lower air volume, or the filter will be partially penetrated, so when the air filter resistance increases to a certain specified value, the filter will be scrapped. Therefore, to use the filter, it is important to master the appropriate use cycle. In case of no damage to the filter, the service life is generally determined by the resistance.


The service life of the primary air filter depends not only on its own merits, such as filter material, filter area, structural design, initial resistance, etc. but also on the dust concentration in the air, the actual air volume used, the setting of the final resistance and other factors.
