portable dust collectors airflow systemsAirflow Systems’ PCH Series portable dust collection systems provide point-source collection of airborne contaminants and prevent contaminants from migrating throughout the facility. The systems are suitable for food processing dusts and powders, grinding dusts and oil mists. The series includes a dynamically balanced, non-sparking, all-aluminum motor to collect contaminants directly at the source without risk of igniting volatile dusts. They include a PCH-1 model, available with a 0.5, 1.0 or 1.5hp motor capable of airflow rates up to 800 CFM.
