Tadpole works in a very simple way by harnessing phenomena created by the circulating pump. As the water enters the Tadpole the action of the pump causes it to spin into a vortex. In the middle of the vortex there is a low pressure zone which is sufficient to draw the dissolved air from solution. As the water reaches the outlet of the Tadpole the action of the vortex increases and the bubbles of air, now out of solution, rise upwards and are collected through a dip tube to be released from the system through an air vent.
