System & device summary

The simple mechanism provides high-efficiency aeration and agitation. The SPAROTOR unit has a simple structure composed of a motor, hollow shaft, screw, and cover. When the special-shaped screw rotates at high speeds under water, a strong agitation flow is created along with negative pressure, and air is supplied through the hollow shaft. This air is sheared by the rotation of the screw, which turns the air into fine bubbles that go into the agitation flow and are dispersed into the water. This helps the system achieve a high oxygen dissolving rate and flow velocity.
