tunnel local fan

The tunnel local fan offers portable, spot-specific ventilation for sections of tunnels or confined spaces that require immediate airflow. It ensures workers have access to fresh air during maintenance or development tasks.

Compact and lightweight, the fan utilizes an axial impeller and integrates with flexible duct hoses for easy redirection. Airflow rates range from 2,000 to 15,000 CFM, sufficient to displace sawdust, fumes, and humidity.

Variable speed drives (VFDs) enable on-demand operation, adjusting airflow in response to sensor inputs for gas levels and temperature. Explosion-proof motor options ensure safety in hazardous atmospheres.

Built-in handles, quick-release duct adapters, and low-noise blades facilitate rapid deployment and minimal disturbance, making the tunnel local fan indispensable for targeted underground ventilation.
