Accessories
| Accessory | Description |
|---|---|
| Atomizer Aerosol Generator | Generates fine aerosol for filtration testing |
| Solid Materials Disperser | Produces solid aerosol particles for standardised tests |
| Aerosol Dilution System | Dilutes aerosols to desired concentration |
| Aerosol Spectrometer | Measures particle size distribution and filtration efficiency |
Test Principle
The system draws controlled airflow through filter media while applying standardized aerosol particles (solid or droplet). Differential pressure, fractional efficiency, and dust loading are continuously measured. Data acquisition provides detailed insight into the filtration performance and operational characteristics of the media under laboratory conditions.
