The FBCDZ series explosion-proof exhaust counter-rotating axial flow fan boasts a unique design that prioritizes efficiency, compactness, and noise reduction.
Impeller Stage:
Counter-rotating design: This innovative approach reduces the need for guide vanes compared to traditional two-stage fans. This translates to a more compact size and lower energy losses within the unit.
Motor Housing:
Flow isolation cavity: The motor resides within a dedicated compartment that isolates it from the airflow.
Dedicated ventilation ducts: Four strategically placed ducts ensure optimal cooling for the motor, maintaining peak performance.
Flow Channel:
Curved collector line and hemispherical fairing: This design creates a uniform flow field before the impeller arrives, minimizing energy loss.
Seamless inner cylinder and impeller hub: The diameter of these components is precisely matched, guaranteeing a smooth flow path without disruptions.
Tapered diffuser core: This feature reduces aerodynamic noise while effectively recovering dynamic pressure.
Fan Blades:
High-strength ZL104 cast aluminum alloy: This material is three times stronger than regular steel, ensuring the blades can withstand normal operation without cracking or breaking.
Three-dimensional twisted design: By combining orthogonal bending and sweeping techniques, this blade design achieves a 5-10% improvement in efficiency and a 10-20dB(A) reduction in noise.
