Overview
This high-performance ventilation duct is designed specifically for the extremely demanding environments of underground mines and tunneling projects. It's more than just a simple pipe; it's a core component that ensures a safe underground working environment and improves construction efficiency.
Mining and tunneling processes generate large amounts of dust, harmful gases (such as methane), and fumes from mechanical equipment. If these pollutants are not removed promptly and effectively, they pose a serious threat to the health and safety of workers and hinder the normal operation of equipment. Our flexible spiral duct was developed to address this core challenge. It continuously delivers fresh air deep underground while efficiently exhausting polluted air, providing continuous, clean air for underground spaces.
