Description: Wind-driven vertical roof exhaust based on the revolutionary free-floating concept actuated by natural convection of the building is assisted by the natural wind outside. It is light in weight, corrosion resistant, maintenance free, energy saving, and provides efficient operation even in a light breeze. Wind turbine ventilator is designed in 3 sizes, 14″, 16″ and 18″, and fitted with teflon bearing, teflon bush, and stainless steel shaft to provide silent operation and trouble-free maintenance. These are built with a heat and friction resistant teflon cap, which provides a near friction-free motion. Vanes are fabricated with special grade aluminium to anodised specification of JIS special grade H24, making it stress resistant.
