Test system for testing particle separation of air filters for passenger compartments

The Test System for particle separation of air filters for passenger compartments is designed to evaluate the particle filtration performance of cabin air filters according to DIN 71460-1 and ISO/TS 11155-1. The system provides precise measurement of differential pressure drop, gravimetric and fractional filtration efficiency, and dust holding capacity. It allows standardized and reproducible testing for R&D, quality assurance, and production control of air filters for automotive passenger compartments. The system can be combined with adsorption test systems (PAF 112) for comprehensive filter evaluation including gas adsorption.
