High-efficiency filters are widely used in various industries and applications that require clean air, such as pharmaceutical, electronics, food, and medical fields. However, different types and grades of high-efficiency filters have different initial resistances, which affect their performance and

Filter material: The selection and application of filter bag material is the core technology of bag-type dust collectors, which affects the performance and lifespan of HEPA filters. Different filter materials should be chosen according to the environment, nature, temperature, and technical requireme

Efficiency is an key indicator of air filters, it reflects the air filter's ability to filter contaminants. MPPS efficiency, counting efficiency, gravimetric efficiency, fractional efficiency, particulate matter efficiency, initial efficiency, minimum efficiency, integral efficiency, local efficiency etc. Add up to a dozen efficiencies, which efficiency should we really be concerned about? What is the significance of each efficiency?

Filters for compressed air are used in a wide range of applications and testing is an important step in ensuring filter performance and effectiveness. Through airflow measurements, particulate capture efficiency tests, oil mist removal efficiency measurements and life assessment, we can fully evaluate the quality and capability of a filter. Through the correct selection and use of compressed air filters, the quality of the process can be improved, the life of the equipment can be extended, maintenance costs can be reduced and more efficient production can be achieved.

As one of the items of clean room inspection, leakage testing of high-efficiency filters has received more and more attention since the implementation of the 2010 version of GMP.
