Key Features
Standard-compliant particle testing
Configured for cabin-filter particle procedures according to DIN 71460-1 and ISO 11155-1.
Fractional-efficiency measurement
Uses controlled aerosol challenge and particle spectrometry for size-resolved separation efficiency.
Dust-loading evaluation
Determines dust-holding behaviour together with differential-pressure development.
Filter media and elements
Modular adapters support both media samples and complete cabin-air filter elements.
Automated operation
Software-guided test routines improve repeatability and operator consistency.
Traceable documentation
Integrated data acquisition supports documented development, benchmarking and quality-control results.
