The VAC-U-MAX Aero-Flex flexible screw conveyors are engineered to transport dry bulk materials at a reduced cost. They convey powders and granular material without separation of product. Also know as a shaftless screw conveyor the VAC-U-MAX Aero-Flex conveyor uses a heavier duty spiral then all its competitors which means less downtime. VAC-U-MAX guarantees the spiral for 2 years.
