1. Water Treatment and Environmental Engineering
This is the largest and most classic application market for centrifugal blowers.

Wastewater Treatment Plant Aeration Systems: Supply oxygen to biological treatment tanks (e.g., activated sludge process), serving as critical equipment for microbial pollutant degradation. Their operational efficiency directly impacts wastewater treatment effectiveness and energy consumption. This is the most common and high-demand application scenario for C-series blowers.

Flotation Systems: Generate micro-bubbles to separate suspended solids, oils, and other impurities from water.

River and Lake Aeration and Reoxygenation: Improve water body ecological environments.

2. Pneumatic Conveying of Materials
Offers stronger handling capacity, longer conveying distances, and higher material density compared to general-purpose fans.

Dense-Phase Conveying: Used for pipeline transportation of particulate materials such as fly ash in power plants, cement, mineral powder, and grains.

Negative Pressure (Vacuum) Conveying: Serves as a vacuum source for central suction systems.

3. Industrial Combustion and Auxiliary Air Supply
Large Industrial Boilers: Provide high-pressure combustion air to ensure complete fuel combustion.

Glass Melting Furnaces, Metallurgical Furnaces: Require stable, high-pressure airflow as an oxidant or cooling medium.

4. Chemical and Process Gas Applications
Process Air Supply: Provide pressurized sterile air for chemical reactors, fermentation tanks (e.g., in pharmaceuticals, food processing).

Gas Circulation: Circulate gases in closed process loops, such as in drying or coating processes.

Inert Gas Generation: Serve as core power equipment for PSA/VPSA nitrogen and oxygen generators.

5. Paper Industry
Paper Drying Section: Provide high-temperature, high-pressure hot air for drying paper sheets.

Stock Preparation Systems: Agitate and transport pulp.

6. Aquaculture
Intensive Farming Pond Aeration: Similar to wastewater treatment aeration principles, provide bottom aeration for high-density fish and shrimp ponds, significantly increasing dissolved oxygen levels.

7. Other High-Pressure Air Supply Scenarios
Vacuum Cleaning Systems: Centralized industrial vacuum cleaning.

Air Test Benches: Provide stable air sources for laboratory or production line testing equipment.

Pneumatic Conveying: Supply air for pneumatic tool stations in factories (smaller in scale than compressor systems but more flexible).
