The specially designed star-shaped closed impeller generates negative pressure in water and aspirates air from above the water surface through an air-pipe. Water is sucked from the large inflow port on top of the impeller housing and mixed with air. This structure prevents troubles that the inflow port is clogged up with sediments on bottom of a tank.
