Product Description
High Quality Oil-free Oxygen Nitrogen Gas Compressors
Minwen high pressure industrial gas compressor belongs to oil-free reciprocating piston type construction. It is divided into three-stage, four-stage or five-stage compression according to the displacement and pressure. It is divided into air-cooled type and water-cooled type according to the cooling type.
An oil-free compressor is a type of gas compressor that operates without the need for lubricating oil in the compression chamber. Traditional gas compressors use oil to lubricate the moving parts and provide a better seal between the compression chamber and the piston or rotor. However, in certain applications where oil contamination is a concern, such as medical and dental facilities, food processing, electronics manufacturing, and painting, oil-free compressors are preferred.
There is no lubricating oil inside the gas compressors, grease lubricated sealing type bearing is adopted for the rotary moving components, the moving seals inside the cylinder are made of self-lubricating material so as to ensure that the compressed gas will never contact any oil.
The machine adopts automatic control mode with low leakage and noise and without the need to arrange dedicated person for attention, and can operate over long term reliably.

This can negatively impact the quality of the compressed air and introduce moisture-related issues downstream.
Contamination:
- Oil Contamination: In some water-lubricated compressors, there is a potential for oil to mix with the water used for lubrication. If oil and water emulsify or if there are leaks in the compressor system, oil contamination may occur. Oil-contaminated compressed air can have adverse effects on downstream processes, equipment, and products. It can lead to contamination, reduced performance of pneumatic components, and potential health and safety concerns.
- Particulate Contamination: Water-lubricated compressors can introduce particulate matter, such as sediment, debris, or rust, into the compressed air system. This can occur if the water supply or water treatment systems are not adequately filtered or maintained. Particulate contamination can clog or damage pneumatic equipment, affect product quality, and cause operational issues in downstream applications.
Preventive Measures:
- Water Separation: Water-lubricated compressors employ various water separation mechanisms to remove moisture from the compressed air. This includes moisture separators, water traps, or coalescing filters that are specifically designed to capture and remove water droplets or mist from the compressed air stream. Regular maintenance and inspection of these separation systems are necessary to ensure their proper functioning.
- Air Treatment: Additional air treatment components, such as air dryers or desiccant systems, can be installed downstream of water-lubricated compressors to further reduce moisture content in the compressed air. These systems help to remove moisture that may have carried over from the compressor and ensure that the compressed air meets the required dryness standards for specific applications.
- Proper Maintenance: Regular maintenance of water-lubricated compressors is essential to minimize the potential impact on compressed air quality. This includes routine inspection, cleaning, and replacement of filters, lubrication systems, and water separation components. Addressing any leaks, malfunctioning components, or system issues promptly can help maintain the integrity of the compressed air and prevent contamination or excessive moisture levels.
By implementing appropriate water separation mechanisms, air treatment systems, and maintenance practices, the impact of water-lubricated air compressors on compressed air quality can be minimized. It is important to consider the specific requirements of the application and follow industry standards and guidelines to ensure the desired compressed air quality is achieved.
