The turbine ventilator is through the turbine balding shell in leaf blade to catches the windward sides blow and push rotor blade shell revolving. because of revolving the turbine balding shell has the centrifugal force, induces the whorl shell inside air discharges through the leeward leaf blades, due to air extraction, causes in the turbine shell lower part the appendix region have the negative pressure, to maintain the air dynamical equilibrium, the positive pressure region's air naturally flow to the negative pressure zone, then achieve the effect of ventilation.
The turbine ventilator include the turbine wheel, the central shaft system, cuts the wind piece, the crossing margin, an altar and so on. It is not only taking natural lighting, moreover the waterproof efficiency may reach 100%.
