The CleanFlo™ Vertical Spiral Screen is a small flow screen specifically designed in a vertical orientation for installation in pump wetwells or short channels.  The screen is composed of a cylindrical perforated or wedgewire basket with an integral shaftless spiral and conveyor tube.  The unit provides screening and conveyance of solids out of the well or channel and can provide additional dewatering of material.  Brushes attached to the spiral in the basket zone provide cleaning of the screen basket during operation.  The submitted CleanFlo Vertical Spiral screen will meet the intent of the specifications and provide the desired functionality within the same overall footprint.
