Ambica engg works wind turbine ventilator, engineered and computer designed to provide optimum air ventilation it is light weighted, high corrosion resistant, maintenance free, energy saving, provides efficient operation even in a breeze of wind turbine ventilator is designed in sizes, 12\", 18\", 21\", 24\" fitted with teflon bushing and stainless steel shaft to provide silent operation and trouble free maintenance. Air vent is a wind, driven vertical roof exhaust based on the revolutionary free, floating concept actuated by natural convection of the building assisted by the natural wind outside rigid construction: air vents are in, built with a heat and friction resistant teflon rods, which provides a near friction, free motion the vanes are fabricated with special grade aluminium vents,powder coatevents,anodiseing vents,and complete stainless steel. Making it stress resistant the teflon self, lubricated impregnated bushing gives a smooth rotation and no maintenance for years. Vent operates on wind energy as well as stack effect
