Spiroflow Systems flexible screw conveyors provide dust-free, low-energy, low-maintenance and low-cost conveying solutions. The motor-driven spiral, which is the only moving part, rotates within a sealed tube, moving materials along by its Archimedean screw action. This design simplicity eliminates the need for any additional operating equipment such as filters or bearings, all adding up to a system that’s hygienic, easy to clean, low on installation and maintenance costs, and high on efficiency and performance. 877/294-9595; www.spiroflowsystems.com.
