What is the filtration efficiency of Bag Type Primary Filter

Bag Type Primary Filter is a common air filtration equipment, widely used in various air conditioning systems and ventilation systems. Its filtration efficiency mainly depends on the quality of the filter material and the structural design of the filter.
Bag Type Primary Filter can filter out most of the dust, microorganisms and other impurities in the air. For particles greater than or equal to 5 microns, its filtration efficiency is usually between 40% and 60%. Although this filtration efficiency seems not high, it is sufficient for primary filtration, which can effectively reduce the burden of subsequent filters and extend the service life of the entire filtration system.
In addition, bag-type primary filter also has the advantages of large dust holding capacity, small resistance, simple structure, safety and reliability. Its filter material fiber has a large dust holding capacity, which can extend the replacement cycle of the filter and reduce the cost of use. At the same time, the resistance of the airflow passing through the filter is small, which can reduce the energy consumption of the air compressor.
In practical applications, bag-type primary filter is often used for pre-filtration of central air conditioning and centralized ventilation systems, as well as pre-filtration of large air compressors, clean return air systems, and pre-filtration of local high-efficiency filtration devices. In addition, high-temperature resistant bag-type primary filter can also be used in air filtration systems that require high-temperature resistant environments.
In short, Bag Type Primary Filter plays an important role in the field of air filtration with its good filtration efficiency and various advantages.
