Features
24/7 Operation: Automated safety features for continuous production.
Short Test Cycle: Complete aerosol supply, analysis, and sample removal within ~30 seconds.
Flexible Quality Standards: Adjustable separation efficiency and pressure drop thresholds.
Minimal Sample Load: Reduces stress on test samples, extending product life.
High Automation and Efficiency: Minimizes operator intervention, improves throughput.
Full Traceability: Barcode/QR code integration ensures complete production tracking.
Principle
A defined volumetric flow rate is sucked by a controlled blower from the environment through a HEPA inlet filter, the test duct and a safety filter. The test duct is composed of three functional sections, i.e., sections for i) the generation and characterisation of the test aerosol (upstream aerosol), ii) the incorporation of the test specimen (specimen adapter) and iii) the characterisation of the downstream aerosol.
Benefits
test system designed for 24/7 operation with automated safety functions
short test cycles (supply, analysis, removal) for separation efficiency and pressure drop
quality criteria for separation efficiency and pressure drop are freely configurable
minimal loading of test specimen (higher lifetime of products)
