Core Characteristics of Water-Lubricated Oil-Free Air Compressors

Time:2026-01-29 16:10:11

As one of the mainstream types of oil-free screw air compressors, the water-lubricated oil-free air compressor adopts pure water/deionized water as the core medium to replace traditional lubricating oil for rotor lubrication, cooling and sealing, thus completely eliminating the oil lubrication system.

1. High Cleanliness of Compressed Air

Throughout the entire operation process, water is used as the lubricating medium without the involvement of any lubricating oil. The oil content in the discharged compressed air is ≤ 0.01mg/m³, which fully complies with the ISO8573-1 Class 0 oil-free standard.

2. More Stable Equipment Operation

Water possesses superior cooling performance, which enables accurate control of the operating temperature of the compressor head. This significantly reduces equipment vibration and noise, while ensuring the stability of discharge pressure and flow rate during operation.

3. Long Equipment Service Life

A uniform lubricating film is formed on the rotor surface by water. When combined with a specialized rotor coating, this film can effectively reduce frictional wear during rotor meshing, thereby extending the service life of the compressor head.

4. Simplified Maintenance Procedures

Maintenance work is only required for a small number of components, such as water filters, precision filters, and water circulation pumps. This greatly simplifies the maintenance procedures and shortens the time required for equipment upkeep.

5. Low Daily Maintenance Costs

Daily maintenance only involves regular water quality inspections, replacement of water filters, and replenishment of pure water, resulting in relatively low overall maintenance costs.

6. Low Operational Threshold

The water circulation system is mostly designed as an integrated structure, featuring a simple overall configuration and few fault points. With basic professional training, operators can complete daily inspections and routine maintenance work.

7. Health and Environmental Friendliness

During the production and operation process, there is no emission of oil mist or oil odor, and no oil pollution is generated. This fully meets the development requirements of enterprises for green production.

8. Adaptability to Diverse Application Scenarios

Benefiting from its water-cooling design, the equipment can operate stably under special working conditions such as high temperature, high humidity, and explosion-proof environments. It is suitable for special industrial scenarios including chemical industry, new energy, and marine engineering.

9. Outstanding Energy-Saving Performance

The water lubrication system exhibits lower operational resistance. When combined with a variable frequency control system, it can dynamically adjust the load according to actual air consumption, thereby effectively reducing electricity costs.

10. Exclusive Processing Systems

The equipment's water circulation system is mostly designed as an integrated unit, equipped with functions such as water quality monitoring, water level alarm, and automatic water replenishment, eliminating the need for dedicated on-duty personnel. It is also equipped with water softening and descaling components to fundamentally solve the problem of scale formation.

11. High-Sealing Design

The main unit adopts a specialized oil-free sealing structure, which ensures dual effects of lubrication and sealing, and reduces the occurrence of equipment failures.

Water-lubricated oil-free air compressors are widely applied in fields that have high requirements for the cleanliness and environmental friendliness of compressed air, such as food and beverage (filling, fermentation), biopharmaceuticals (pharmaceutical production, medical devices), electronic semiconductors (chips, precision components), precision coating, new energy (lithium batteries, photovoltaic industry), municipal water supply, and laboratories. They also serve as core supporting equipment for the transformation of modern industry towards "precision and green development".
