Direct Driven Contra – Rotating Fan

The Direct Driven Contra-Rotating Fan is an advanced axial fan system engineered for applications demanding high airflow combined with higher static pressure. It features two axial impellers mounted in series and rotating in opposite directions, which significantly improves pressure development and overall efficiency compared to conventional single-stage axial fans.

Each impeller is directly driven by its own motor, eliminating belts and mechanical transmission losses. This direct-driven configuration ensures precise speed control, reduced maintenance, and consistent performance. The contra-rotating design recovers swirl energy, reduces turbulence, and delivers a more uniform airflow profile.

Manufactured using high-quality, durable materials, the Direct Driven Contra-Rotating Fan is suitable for continuous-duty and demanding environments. It is widely used in tunnels, metro and rail projects, power plants, industrial ventilation systems, smoke extraction, and large HVAC installations where space constraints and high performance are critical.

Key Advantages:

• Very high airflow with increased static pressure

• Contra-rotating impellers for superior efficiency

• Direct-driven motors for low maintenance and reliability

• Compact design with high performance output

• Ideal for tunnels, industrial ventilation, and large HVAC systems
