Patent attributes
A peller device with a flap is an apparatus used to enhance the capabilities and efficiency of water circulation and aeration systems. The apparatus is configured to act as both a propeller and an impeller as necessary for a particular water circulation requirement. A flap is an addition to the blade tip which propels a fluid by pushing against the fluid, thus enabling the peller to function as a propeller. In addition, the flap facilitates the generation of a sucking force so the peller can also function efficiently as an impeller. The peller assembly can be encased in circular housings having a vertical axis in which the peller assembly is mounted for rotation on the central axis of the housing. The peller assembly is formed with a hub and a plurality of blades symmetrically positioned around the hub. The flap of the apparatus is attached to the base of the peller assembly.
