Our products are designed and manufactured according to standards, including respirator standards such as EN 149、EN 143、NIOSH 42 CFR Part 84、EN 14683、ASTM F3502、GB 2626、GB/T 32610、GB 19083、YY 0469、YY/T 0969, etc. Filter standards such as ISO 16890、EN 1822、ISO 29463、ISO 11155、IEST-RP CC001.5、GB/T 14295、GB/T 6165、GB/T 13554, etc.
From the perspective of users, our products have good practicability and high accuracy. Our customers are distributed in filter media, masks, filters (element), clean rooms and other industries, as well as environmental protection industries with monitoring requirements for air quality. Customers include relevant production enterprises, testing institutions and research institutes at home and abroad.
ISO 29463 originates from EN1822, which defines EPA, HEPA and ULPA filters commonly used in industry. While ISO 29463 maintains the classification of EPA, HEPA and ULPA.But replace E10-E12, H13-H14 and U15-U17 with the following 13 filter levels. The ISO 29463 can't replace EN 1822, EN 1822 will continue to be valid.
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.
