Hardworking Devices That Mother Nature Pays to Operate.

As an alternative to mechanical ventilation, the rooftop rotary ventilator now is not only widely accepted as industrial ventilation, but also has become a common ventilation feature used in other types of buildings including institutional, commercial and residential.
Due to the simple operating mechanism and relatively affordable price, a rotary ventilator which is driven by natural wind force may be a preferred choice to ventilate the building without depending on mechanical ventilation. |

Should the interior become hot or stale, doors and windows can be opened, however stale and hot air will not disperse by itself. As a result, the opening of doors and windows is simply not sufficient to provide ventilation in most buildings.
Unlike doors, windows and static ventilation, Rotary ventilators draw air upwards creating convection current and in the process they extract stale air, together with air which has become hot as the result of the building's exposure to long hours of sunlight. Heat from manufacturing equipment within the building is also extracted by these efficient ventilators. As the stale and hot air is extracted it is replaced by fresh air at ambient temperature entering through doorways and openings thus completing the convection cycle current and improving the internal environment. |

Needless to say, fresh air makes people feel more alive and vitalised whilst stale air causes people to feel lethargic and disinterested. On hot days the movement of air over the body causes evaporation to occur which is the natural way to cool down and helps prevent moderate heat stress.
Rotary Ventilators also help prevent condensation by extracting condensation-forming air, and in case of fire will extract smoke and fumes, preventing the building from becoming smoke filled and assisting the occupants to escape to safety. They are hardworking devices that Mother Nature pays to operate. |
