Lean phase vacuum conveying system for powder handling
Efficiently transport and separate powders and granules with precision using lean phase vacuum conveying, optimizing your production line by maintaining product integrity over medium distances while ensuring constant flow and minimal material degradation.

Conveys and Separates Powders and Granules
The Lean Phase Vacuum Conveying System from GEA Powder Handling is designed to efficiently transport powders and granules across medium distances. Employing positive displacement exhausters, this system operates under low to moderate vacuum pressures, ideal for conveying materials like pharmaceutical powders, powdered milk, and cosmetic powders. It operates continuously with a capacity of less than 10 tonnes per hour, ensuring smooth integration into existing production lines.
The system’s versatility makes it suitable for diverse industries, including pharmaceutical, food, and chemical sectors, conveying materials from multiple sources to a single destination. The lean phase design allows for cost-effective pipeline installation, thanks to lower operating pressures. Constructed with durable materials, it provides options like stainless steel for environments requiring chemical resistance.
GEA’s lean phase system supports seamless integration with remote monitoring and control capabilities, enhancing operational efficiency. It complies with industry standards, ensuring safe and effective handling of sensitive materials. The system is also engineered for easy cleaning, with features like a rotary valve feeder that simplifies maintenance and reduces downtime.
