Aerodynamic Breakthroughs---Blauberg fans & Engineering Impeller Science

Backward-Curved Designs

Blade exit angle optimized to 32°, minimizing flow separation (CFD-verified). Efficiency reaches 84% at 3000 RPM.

Forward Multi-Wing Blades

56 airfoil-section blades increase pressure coefficient Cp by 0.18 (vs. standard 45-blade designs).

Axial Rotor-Stator Synergy

Glass fiber reinforced nylon impellers reduce tip clearance to 0.5mm, boosting volumetric efficiency to 78%.

Advanced Acoustics

Centrifugal blowers: Mid-mounted EC motors eliminate 1.6kHz resonance peaks

Tangential fans: 3-phase sinusoidal drive electronics cut electromagnetic noise by 15 dB

Reliability Engineering

60,000-hour bearing life (L10 rating at 40°C)

IP55 wet-environment models pass 500-hour salt spray testing (ASTM B117)

-30°C cold-start capability (Arctic application validated)

Conclusion

Blauberg’s EC-driven fan systems deliver measurable sustainability and performance advantages, with third-party verified efficiency exceeding global regulatory standards.
