The D.I. Filter Testing Machine is designed and manufactured for comprehensive evaluation of filtration performance across a wide range of industrial and automotive filter products. Engineered to deliver highly accurate and repeatable results, the system measures filtration efficiency, aerosol penetration, pressure drop, and overall filter quality using internationally accepted aerosol-based testing methods. Compatible with both poly-dispersed and mono-dispersed oil or sodium chloride aerosols, the machine is suitable for testing air filters, HEPA filters, cabin filters, respirators, filter cartridges, industrial filtration media, and protective filtration products. Equipped with precision sensors, automated data acquisition, and intelligent reporting software, the system enables manufacturers, quality control laboratories, and research facilities to validate filter performance while maintaining compliance with customer and international testing standards. The D.I. Filter Testing Machine can be customized with different aerosol generation systems, airflow capacities, software modules, automation levels, and fixture configurations to meet specific testing applications and production requirements.
