Hot air doesn't disperse by itself and opening doors and 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 building's occupants. No power for this Ventilators, unlike door or window, drown air, together with tech air which has become hot due to the building's exposure to long hours of sunlight and from manufacturing processes within the building. Easy to say, fresh air make people feel more energetic whilst air causes 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- densation by extracting moist condensate forming air, and in the case of fire will extract smoke and fumes thus preventing the building from becoming from becoming smoke filled and aiiowing the occupants to escape to safety and secure. Working Process Turbine ventilator operates by utilizing the velocity energy of the wind 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 after the breeze has stopped, the fly wheel effect of the rotor cage will use its stored energy to continusly remove air giving rise to ventilation. Suction is maintained even at low wind velocities. Benefit from Product
