Air Collection and Silencing
Air Collecting Front Anechoic Barrel: This initial section is designed to intake air while minimizing noise, acting as the first barrier against high-speed airflow noise.
Stage 1 Anechoic Main Unit: Housing the first impeller, this unit is integral to the fan’s noise reduction capabilities, ensuring quieter operation from the outset.
Impellers and Energy Transfer
Stage 1 and 2 Impellers: These impellers are directly mounted and driven by flameproof motors. Their contra-rotating design (rotating in opposite directions) significantly enhances efficiency by improving airflow dynamics and minimizing energy loss.
Post-Stage Impeller: Functioning similarly to a guide vane in traditional axial flow fans, this final impeller accelerates airflow and boosts wind pressure, contributing to the fan’s overall high performance.
Unique Design Features
Contra-Rotating Impellers: The unique design of contra-rotating impellers eliminates the gas pulsation typically associated with such systems. This results in smoother operation and more stable airflow, enhancing the fan’s reliability and performance.

Application
n coal mines, the primary function of the underground axial vane ventilation system is to remove methane, a highly flammable gas that poses a significant explosion risk. Additionally, these systems are crucial for controlling dust levels, which can lead to respiratory problems for miners. The fan blower effectively enhances air quality and safety in coal mining operations by ensuring continuous and efficient ventilation.
In metal mines, the fan blower plays a vital role in removing radon, a radioactive gas that significantly increases the risk of lung cancer. It also helps to manage and reduce heat levels, which can be a major safety hazard, particularly in deep mines. By providing reliable ventilation, the fan blower ensures a safer working environment and enhances overall operational efficiency.
For quarrying operations, the fan blower is essential in removing dust and fumes generated by crushing and grinding activities. These operations can produce significant amounts of particulate matter and heat, both of which pose health and safety risks. The fan blower helps to control these hazards by maintaining adequate airflow and temperature regulation, ensuring a safer and more comfortable working environment in quarries.
Advantages
The fan’s two-stage structure seamlessly integrates a no-guide vane axial flow local fan with an embedded panel-type silencer. This combination ensures efficient airflow while significantly reducing noise emissions, providing a quieter and more efficient ventilation system.
The use of contra-rotating impellers eliminates gas pulsation, resulting in smoother operation and improved efficiency. This design innovation enhances the fan’s performance, making it more effective in maintaining optimal ventilation in mining environments.
The fan blower is capable of adapting to varying ventilation needs through its multi-stage operation. Whether a single or multiple stage operation is required, the fan can be configured to meet specific ventilation demands, ensuring maximum efficiency and flexibility in different scenarios.
