dual impeller fan

Dual impeller fans feature sequential impellers rotating in opposite directions on the same shaft. The first impeller accelerates the airflow and introduces swirl, while the second recovers swirl energy, boosting static pressure and overall efficiency.

These fans achieve pressure gains up to 20% higher than single-stage units while maintaining compact footprints. They deliver flows up to 50,000 CFM at pressures to 4 kPa, making them ideal for local mine ventilation and industrial process applications.

Constructed with balanced impellers and sealed bearings, dual impeller fans reduce vibration and extend service intervals. Integrated IE4 motors and variable frequency drives (VFDs) allow adaptive speed control, matching airflow to real-time demands.

Quick-release bearing housings and diagnostic sensors streamline maintenance. Dual impeller fans represent an advanced solution for high-performance airflow needs where space and pressure requirements are critical.
