SAG 420 Solid Aerosol / Dust Disperser
High-mass-flow belt-dosing dust disperser for reproducible powder aerosol generation in engine-intake filter testing, dust loading and large-scale filtration studies.
Model Overview
| Model | Group | Positioning | Core fit |
|---|---|---|---|
| SAG 420 | High-mass-flow belt-dosing dust disperser | Precision belt feeder with compressed-air dispersion for controlled high-rate powder aerosol generation | Engine-intake filter testing, high-capacity dust loading and large filter-system development |
Key Features
Very wide mass-flow range
Provides approximately 6–6,000 g/h for both development studies and heavy dust-loading tests.
Precision belt dosing
Separates powder feed from dispersion airflow for controlled and reproducible mass delivery.
High carrier flow
Supports 3,000–18,000 L/h aerosol flow for large ducts and intake-filter test systems.
Standard test-dust compatibility
Designed for compatible free-flowing, non-abrasive and non-cohesive powders below 200 µm.
