Bunting’s pneumatic metal detectors and separators are designed to detect and remove metal contaminants from materials conveyed through vacuum or pressure pneumatic lines. Engineered for precision in both food-grade and industrial environments, these systems ensure product purity and protect downstream equipment in applications ranging from flour and spices to plastic pellets and regrind.

Featuring high-sensitivity detection, advanced self-monitoring, and fast-acting reject systems, Bunting’s pneumatic units integrate easily into new or existing pipelines. Optional configurations are available for hygienic washdown, ATEX-rated environments, and Clean-in-Place (CIP) systems, delivering reliable performance in even the most demanding production settings.

By catching metal contamination early—before it damages equipment, compromises quality, or reaches customers—Bunting pneumatic detectors help manufacturers reduce downtime, avoid costly recalls, and maintain compliance with strict safety and quality standards. The result is greater operational efficiency, improved product integrity, and long-term protection of both brand and equipment.
