Daylighting Natural Ventilator

Daylighting natural ventilator has typical advantages such as low height, light weight, small load, good wind resistance, and low steel consumption, which can reduce the total investment for end users. The unique ventilation structure design inside the roof louver vent can reduce the loss of smoke, dust and mist in the flow by guiding the airflow to move upwards and improve the ventilation efficiency. By installing the opening and closing valve plate, the amount of ventilation, smoke and daylight can be adjusted through the valve plate.
