Natural Turbine Ventilator
The turbine ventilator operates by utilizing the velocity energy of the win d to induce air flow by centrifugal action. The centrifugal force caused by the spinning vanes creates a region of low pressure area which draws air out through the turbine. Air drawn out by the turbine is continuously replaced by fresh air from the outside. The slightest breeze will cause the turbine to spin and even otter the breeze has stopped, the fly wheel effect of the rotor cage will use its stored energy for continuously remove air giving rise to ventilation. Suction is maintained even at low wind velocities

Factories, warehouses, workshops and even community buildings are
frequently constructed without an efficient natural ventilation system for
the benefit of occupants.
And, if the interior of the building get hot and stale, there’s always door or
window that can be opened to provide for the ventilation.
However, stale and hot air doesn’t disperse by itself and opening doors or
windows is simply not sufficient to provide adequate ventilation in most buildings.
But, by installing AIRVENT Turbine Ventilators, you can provide an efficient
and cost effective system of natural ventilation for the benefit of the
These powerless Ventilators, unlike door or window, draw air upwards, creating a convention
current, and in the process it is extracting stale air, together with the air
which has become hot due to the building’s exposure to long hours of sunlight and from manufacturing processes within the building.
As the stole and hot air is extracted by the ventilators, it is replaced by fresh air at ambient temperature entering
through always and openings thus completing the convention cycle current and improving internal environment.
Needless to say, fresh air make people feel more energetic whilst stole air ca uses people to feel tired and on hot days the air movement over the body causes evaporation to occur which is the natural way of cooling down and reducing heat stress on the body.
Air vent Turbine Ventilator also helps to prevent con-dentations by extracting moist condensate foaming air, and in the case of fire will extract smoke and fumes thus preventing the building from becoming smoke filled and allowing the occupants to escape to safety.

Calculation for Exact Quantity
Determine volume of space to be ventilated
Volume (ft3) = L x W x H
Where L = Length, W = Width, H = Height of building
Select Air change Rate
Calculate required ventilation rate Q (cfm)
Q (cfm) =(Volume (ft3) X Air change Rate)/60
Determine number of ventilation= (Ventilation Rate Q)/(Exhaust Capacity)
