Working Principles


Multi-Stage Air Processing Cycle

The Water-Lubricated Air Compressor operates through a systematic five-step process that ensures clean, dry, oil-free compressed air. Each stage is engineered to optimize efficiency and air quality, from initial intake to final emission.


Step-by-Step Operational Flow

Intake Process: Ambient air is drawn through an intake filter, removing initial contaminants before entering the compressor unit. A set of rotating impellers supercharges the air, preparing it for compression.

Compression Stage: The supercharged air enters an oil-free screw mechanism, consisting of fixed and movable screws. As the screws rotate, the movable screw compresses the air with the assistance of the fixed screw—with water acting as both a lubricant and cooling agent.

Cooling Stage: Compressed air generates heat during compression, which is dissipated by a dedicated water-cooling system. Circulating water in cooling pipes lowers the air temperature, bringing it closer to the suction temperature for enhanced efficiency.

Separation and Drying: The cooled air passes through a separator to remove water and any residual particles. Further drying is achieved via adsorption or condensation dryers, eliminating moisture to ensure the air meets strict dryness standards.

Emission Stage: The final oil-free compressed air is stored in a dedicated container, equipped with discharge valves that release air to the service system as needed, ensuring a steady supply for applications.

Characteristic Advantages


Superior Air Quality

The water-lubricated, oil-free design eliminates oil contamination, providing oil-free compressed air that meets the strictest purity standards. This is critical for industries such as food, beverage, and pharmaceuticals, where air quality directly impacts product safety.


High Energy Efficiency

The compression process closely mimics isothermal compression, thanks to the water-cooling system, which keeps air temperature low and enhances efficiency. Additionally, frequency conversion operation in select models further reduces power consumption, lowering operational costs.


Low Maintenance Costs

With no oil changes, oil filter replacements, or oil separator maintenance required, the compressor minimizes routine servicing needs. The water-lubrication method also cleans internal components, extending the maintenance cycle and reducing the risk of breakdowns. The symmetrical rotor structure reduces bearing load, prolonging the main engine’s service life.
