Ventilation on Demand in Mining: Insights from Paul’s Fan Company & PAAC Featured in North American Mining

Ventilation on demand (VOD) continues to gain attention across the mining industry as operations look to improve efficiency, reduce energy use, and better manage airflow underground. But while the concept is straightforward, successful implementation requires more than simply adding controls or adjusting fan speeds—it requires a system-level approach.

Paul’s Fan Company and Paul’s Automation & Controls were recently honored to contribute to a featured article in North American Mining, where Todd Elswick and Jim Harmon shared practical, real-world insight into how ventilation on demand systems perform in active mining environments.

Drawing from decades of combined experience in ventilation engineering and control system integration, the article explores how main fans, auxiliary fans, controls, and monitoring systems must work together to deliver reliable airflow. It also highlights common challenges operations face when VOD is approached as a standalone upgrade rather than a fully integrated system.

From system design considerations to long-term performance expectations, the discussion reinforces a key takeaway: ventilation on demand is most effective when it is engineered around the realities of the mine—not just theoretical models.
