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.
