Production Description
The Raw Material of TG Turbine Ventilations:
I) TG Turbine Ventilations are made of the stainless steel.
II) We use the advanced UBC bearings from USA.

The Operating Theory of TG Turbine Ventilation:
l The undulating vanes lead to smooth rotation at light wind. The bearings at lower and upper position make smooth turns.
l 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.
l Because the turbine is went on rotating, the fresh air outdoor can enter into the room continually so that the room can ventilate conveniently.
l The single rotating mechanism will work normally except there is the severe natural damage during 15 years.
