Pillar 1: High-Efficiency Aerodynamics – Engineering the Heart of Airflow

Traditional radial or forward-curved impellers are inefficient and have narrow operating ranges, causing energy spikes and instability.

We employ backward-curved impellers. While offering slightly lower maximum pressure, their “non-overloading" power characteristic and wider efficient operating range make them ideally suited for the variable conditions of street sweeping. They maintain high efficiency across different suction demands, saving energy.

Simple, flat blades create turbulent eddies and airflow separation, wasting energy and causing pulsations.

We design impeller blades with complex three-dimensional curvature and twist angles, optimized using Computational Fluid Dynamics (CFD) simulations. This smooths the airflow path within the volute, drastically reducing secondary flow losses and converting more motor power into effective suction.

An impeller and volute mismatched in dimensions create bottlenecks and inefficiencies.

We meticulously calculate key parameters—inlet diameter, outlet width, blade inlet angle—to ensure the impeller and volute are perfectly harmonized. This guarantees the blower operates at its peak efficiency point under typical working conditions.
