According to the ISO16890-2016 standard, the test bench is mainly used for the testing of general ventilation air filters. Based on the performance results determined in the test procedures, the filters are classified (particulate matter ePM). In the air filter test, two types of artificial aerosols, oily and saline aerosols, are used to measure the comprehensive efficiency within the particle size range of 0.3μm to 10um. Coarse aerosol (artificial test dust) is used to obtain the test dust holding capacity and weighing efficiency.
ISO16890-2016
All key instruments are of imported brands, ensuring accurate data during testing.
2. The installation fixture adopts pneumatic sealing, which is convenient and fast.
3. The test pipeline adopts a rotating structure, making the installation of the filter more convenient.
4. The pipeline design uses fluid analysis for airflow simulation, and the designed structure is more in line with the testing standards.
