Our RHINOTUFF Roof Ventilator is a natural ventilation system, which works on wind as well as pressure and temperature difference inside and outside the buildings.

It helps create a healthy & congenial work environment by helping remove inside hot stale air & by facilitating entrance of outside fresh air through the various openings in the shed. 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 breeze & 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 Roof 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, corrosive and obnoxious gases and 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., but varies depending on the wind speed, stack height and the temperature difference inside and outside the building.
