Product Description

1 Product Description

As a non-powered natural exhaust device, the natural ventilator works continuously around the clock without the need for human intervention or electrical power.

Once installed, it gently yet effectively removes contaminated, humid, and high-temperature air from the working environment while consistently providing fresh air to ensure a comfortable and optimal working atmosphere.

Moreover, during the winter season, it helps prevent indoor condensation, thereby protecting the fire-retardant coating on the inner wall of the roof panel from moisture-related damage and peeling.

2 Component

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.

Please note that under typical 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 is around 5°c. If the temperature difference between indoors and outdoors is less than 5°c, consider increasing the number of installed ventilators to enhance airflow efficiency.
