Claim:
1. A separation removal and circulation system of air bubbles in fluid comprising: (1) a main tank which stores fluid containing air bubbles to be removed therefrom; (2) a first air bubble separation apparatus operatively connected to the main tank such that the fluid stored in the main tank and containing air bubbles to be removed therefrom can be introduced into said first air bubble separation apparatus for separation into a first fluid with air bubbles removed therefrom and a second fluid containing air bubbles, so that air bubbles is separated and removed from the fluid containing air bubbles to be removed therefrom; (3) a second air bubble separation apparatus operatively connected to the first air bubble separation apparatus such that the second fluid separated from the first air bubble separation apparatus can be introduced into said second air bubble separation apparatus for separation into a third fluid with air bubbles removed therefrom and a fourth fluid containing air bubbles, so that air bubbles is separated and removed from the second fluid; and (4) a sub-tank operatively connected to the second air bubble separation apparatus such that the fourth fluid separated from the second air bubble separation apparatus can be introduced into the sub-tank, said sub-tank being configured so that air bubbles contained in the fourth fluid are captured and combined with each other so as to be removed from the fourth fluid, and wherein the second air bubble separation apparatus comprises:
