Vents and Hatches

Factories, warehouses, workshops, houses, and even community buildings are frequently constructed without an efficient natural ventilation system for the benefit of occupants.

Should the interior become hot or stale, doors and windows can be opened, but stale and hot air will not disperse by itself. As a result, just opening doors and windows is simply not sufficient to provide ventilation in most buildings.

Unlike doors, windows and static ventilation, rotary ventilators draw air upwards to create a convection current. In the process they extract stale air, along with air that has become hot due to 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 that enters through doorways and openings, which completes the convection cycle current and improves the internal environment.
