auxiliary fan

An auxiliary fan is a specialized ventilation device used to provide additional airflow in environments where primary ventilation alone is insufficient. These fans are commonly installed in mining tunnels, underground passages, factories, and other confined spaces to enhance air movement and ensure a safe working atmosphere.

Auxiliary fans support the main ventilation system by directing fresh air to remote or hard-to-reach areas, removing hazardous gases, and maintaining adequate oxygen levels. Their compact design, energy efficiency, and reliable performance make them essential equipment for modern underground and industrial ventilation projects.
