The Spiroflow CABLEflow tubular cable drag conveyor is designed for gentle product handling and installations requiring conveying in multiple planes; DYNAflow tubular chain drag conveyors operate within the confines of a pipe with discs within the pipe connected by articulated metal links and are suited for a range of stringent applications. The Spiroflow Aero-Mechanical conveyor requires no air filtration equipment; it has a patented automatic rope tensioning, monitoring adjustment system that automatically measures and adjusts rope tension and indicates when the rope has to be replaced.
