The FlexMAX^® family of flexible screw conveyors manufactured by Erie Technical Systems Inc. is a rugged and reliable way to feed a variety of bulk materials. Our flexible screw conveyors come standard with an inlet hopper, screw casing, helical screw, discharge head, and a motor with a gear reducer. The bulk material is transferred up or along with the casing by the rotating flexible screw. Our flexible screw conveyors are commonly used with our UltiMAX^TM bulk bag unloaders, bag break stations, or large storage hoppers.
