Product Description

  1. Designed for every cross-cut between underground intake and return airways, as well as between main intake and return airways, ensuring efficient ventilation control in coal mines.

  2. Features low opening force, allowing personnel and vehicles to pass through easily without excessive effort, improving operational efficiency underground.

  3. Eliminates the need for additional reverse air doors, reducing installation costs and simplifying the ventilation system layout.

  4. Automatically closes after personnel or vehicles pass through, maintaining proper airflow and preventing air leakage without manual intervention.

  5. Recognized as a relatively ideal type of air door for underground coal mines in China, offering reliable performance, safety, and low maintenance.
