They are for new or retrofit installations that don't allow for impeller assembly inside a tank. Models install through mixture mounting nozzle. They feature hydrofoil-style, four-blade design. It folds for easy installation and opens via centrifugal force - locking in place when fully opened. This eliminate the need for workers to enter a tank. The blade locking mechanism can be accessed from outside a tank to remove the mixer if necessary.
