Our RHINOTUFF Wind Turbine Ventilators is a natural air ventilation system, which helps create a healthy & congenial working environment by helping improve the air circulation in the place of installation.


It is a free spinning roof ventilator, which works by utilizing the Velocity Energy of wind to induce air flow through Centrifugal Action.


The Fan starts revolving due to the force of the outside wind & the inside hot air. The Centrifugal Force (backward thrust) caused by the spinning vanes creates a region of low pressure, which draws and throws out air from below and causes fresh cool air from the outside to come in.

The slightest breeze will cause the Turbo Ventilators to spin. Even after the breeze has stopped, the fly wheel effect of the rotor cage will used its stored energy to continuously remove stale air, gases, fumes & smoke giving rise to ventilation. Suction is maintained at very low levels of wind velocity.

Convective thermal currents are given boost by venture dome to further enhance revolution of the Ventilator.


Cooler air from the outside will rush into the negative space in the building to maintain a condition of equilibrium. Stale hot air is always exhausted through the Fan, whereas fresh air only comes in through the openings in the building. The incoming outside air could be filtered by installing filters over the inlets. This is necessary in case of pharmaceutical & food processing industries.

Their maximum exhaust capacity is 2700 C.F.M. It depends on the following three factors: 

1. Wind velocity 
2. Difference between the inside and outside temperature
3. The height at which the Ventilators are installed

Standard sizes are - 24'', 22'' & 21''
