Product Information:

According to ISO 16890 standard, the test bench is mainly used for testing general ventilation air filters. Based on the performance results determined by the test procedure, filters are classified (particulate matter PM). Two types of artificial aerosols are used in the air filter test. The aerosol is used to measure the overall efficiency in the particle size range of 0.3 μm–10 μm. The coarse aerosol (artificial test dust) is used to obtain dust holding capacity and gravimetric efficiency.
