01 / Application
Workflow and key features
The KLW-01A challenges a clamped specimen at the required airflow and compares particle concentration across the material to calculate filtration efficiency. It supports development and quality control of protective masks and filter media.
- Wide efficiency range covers routine and high-efficiency mask materials
- Controlled airflow is matched to the selected test method
- Compact integrated structure reduces laboratory footprint
- Fixture design stabilizes the specimen during the particle challenge
- Challenge aerosol, flow and reporting method are confirmed for the application
