As a non-powered natural exhaust device, the natural ventilator operates without requiring human intervention or electrical power on a 24-hour basis.
Upon installation, it effectively expels contaminated, humid, and high-temperature air from the working environment while continuously supplying fresh air to maintain an optimal working atmosphere.
Additionally, it prevents indoor condensation during winter months, thus safeguarding the fire-retardant coating on the inner wall of the roof panel against moisture-induced damage and peeling.
The body of the non-powered ventilator is constructed from high-quality stainless steel, ensuring durability even in harsh environmental conditions.
The specially designed fully enclosed bearing system is housed within a specialized casing, guaranteeing that the turbine operates continuously and stably under normal working conditions without requiring maintenance.
The unique support structure enhances the ventilator's ability to withstand strong winds, ensuring reliable performance in demanding weather scenarios.

Note: Under normal conditions, the annual average wind speed is 3.4 m/s (equivalent to Beaufort scale level 3), and the temperature difference between indoor and outdoor environments is approximately 5°C. If the indoor-outdoor temperature difference is less than 5°C, the number of installed ventilators can be increased to enhance airflow.
