Alsynite has a range of residential vents and industrial vents. Alsynite Industrial Turbine Ventilators are available 150mm, 300mm, 600mm and 900mm diameter. Powder coating is available in most common steel roofing colours.

Unlike doors, windows and static ventilation, rotary ventilators draw air upwards to create 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.
