2、 Main purpose

1. Environmental water treatment (core application)

• Sewage aeration: provides high-pressure oxygen for biochemical and aerobic tanks, enhances microbial decomposition, and improves treatment efficiency.

• Air flotation/sedimentation: generates tiny bubbles, separates suspended solids, oil stains, and impurities in water, and is used for industrial wastewater and municipal sewage purification.

• Sludge drying: Provides high-pressure airflow to reduce the moisture content of sludge, facilitating subsequent disposal.

2. Pneumatic conveying (industrial material conveying)

• Conveying powders, granules, and small materials such as cement, flour, grains, plastic pellets, and chemical raw materials, achieving closed pipeline transportation without dust leakage.

• Vacuum feeding: used for injection molding, powder processing, food ingredients, etc., to suck materials into the hopper through negative pressure.

3. Printing/Packaging/Textile

• Paper adsorption and conveying: In printing machines, laminating machines, and paper cutting machines, negative pressure adsorption of paper is used to prevent paper jams and deviation, ensuring accuracy.

• Label bonding, blown film, bag making: Provide stable airflow to complete bonding, cooling, and shaping.

• Textile: air suction and dust removal for weaving machines and carding machines, yarn drying.

4. Food/pharmaceutical processing

• Drying and Cooling: Rapid dehydration and cooling of potato chips, cookies, fruits, vegetables, and medicinal herbs to maintain quality.

• Mixing/Fermentation: Ventilation and oxygen supply for fermentation tanks and mixers to improve efficiency.

• Clean transportation: Transporting food raw materials and pharmaceutical powders without oil, water, or pollution.

5. Industrial dust removal and ventilation

• Dust collection: High pressure dust removal in woodworking, metal processing, sandblasting, and polishing workshops to efficiently collect dust.

• Equipment cooling: forced air cooling for boilers, motors, transformers, and production lines.

• Waste gas transportation: pressurized transportation and treatment of waste gases from chemical and metallurgical industries.

6. Other special scenarios

• Aquaculture: aerating fish ponds, shrimp ponds, and fish ponds to increase dissolved oxygen in water.

• Spraying/surface treatment: high-pressure airflow spraying, workpiece blowing, surface drying.

• Gas pressurization: process gas pressurization and transportation in chemical, pharmaceutical, and metallurgical industries.
