General Ventilation Test Bench
The General Ventilation Test Bench is designed to evaluate the performance of general ventilation air filters. Based on ISO 16890-2016, the system measures filtration efficiency across particle sizes from 0.3 μm to 10 μm, using both oily and saline aerosols. Coarse aerosols (artificial test dust) are employed to determine dust holding capacity and final life efficiency. The test bench ensures accurate classification of air filters according to particulate matter efficiency (ePM).
