Product Description

Rthe diameter of ball part is 24inch, the diameter of neck(throat) is 20inch. the raw material of tg turbine ventilators: ¿) tg turbine ventilators are made of the stainless steel, galvanized sheet and aluminium. ¿) we use the advanced ubc bearings from the usa. the operating theory of tg turbine ventilators: the undulating vanes lead to smooth rotation by light wind. the bearings at lower and upper position make smooth turns. the motility created by the rotation of the vanes brings the hot air, smoke and wet air up to the roof and exhausts them out. because the turbine is went on rotating, the fresh air outdoor can enter into the room continually so that the room can ventilate conveniently. the single rotating mechanism will work normally except there is the severe natural damage during 15 years. our turbine ventilators are possessed with the following traits: no power exhausting, saving energy and money; anti-acid-base, anti-erosion, long-lived used; no noise, no pollution, absolutely envi
