Air Collection and Silencing:
Air Collecting Front Anechoic Barrel: This section acts as the initial point of air intake and features noise reduction properties.
Stage 1 Anechoic Main Unit: This houses the first impeller and contributes to noise dampening.
Impellers and Energy Transfer:
Stage 1 and 2 Impellers: These directly mounted impellers are driven by flameproof motors and rotate in opposite directions for increased efficiency.
Post-Stage Impeller: This final impeller functions similarly to a guide vane in a traditional axial flow fan, further accelerating airflow and boosting wind pressure.
Unique Design Features:
Contra-Rotating Impellers: The opposing rotation of adjacent impellers eliminates the gas pulsation common in contra-rotating fans, leading to smoother operation.
Prime Number Blade Count: To prevent blade overlap and maintain efficient airflow, the number of blades between adjacent stages uses prime numbers.
