Features
standard compliant testing of filter media and filter elements
combined testing with particles and with gases
very flexible system configuration possible
Principle of Operation
Defined airflow passes through the HEPA inlet filter and the test duct.
The test filter is installed in the adapter, ensuring easy insertion and observation.
Particle aerosols and specific gases are injected upstream of the filter.
Downstream, laser aerosol analyzers and gas analyzers measure particle concentrations and gas composition.
The system calculates fractional efficiency, dust loading, and adsorption/desorption curves.
The exhaust system ensures stable gas conditions and safe operation during filter replacement.
Software allows automated, repeatable testing and data recording/analysis.
