The natural ventilator is a non-powered, environmentally friendly device that operates continuously 24 hours a day without requiring human intervention or electrical power. Upon installation, it effectively removes stale, humid, or overheated air from the workspace while consistently supplying fresh air to maintain a comfortable and healthy environment for occupants. Furthermore, during the winter season, it reduces indoor condensation, thereby safeguarding the fire-retardant coating on 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.
Our product supports customization. For further information, please do not hesitate to contact us.

Please be advised that, under standard conditions, the annual average wind speed is approximately 3.4 m/s (equivalent to Beaufort scale level 3), and the temperature difference between indoor and outdoor environments typically ranges from around 5°c. In cases where the temperature differential between indoors and outdoors is less than 5°C, it is recommended to increase the number of installed ventilators to improve airflow efficiency.
