What is the difference between oil-free air compressor and ordinary air compressor?

The main differences between oil-free air compressors and ordinary air compressors are reflected in the working principle, gas cleanliness and application scenarios, as follows:

1. Lubrication and cooling method
ordinary air compressors usually rely on lubricating oil to achieve sealing, lubrication and cooling during compression, and the oil system is its core component. The oil-free air compressor (such as granklin water lubricated screw air compressor) adopts innovative design, replaces lubricating oil with water, and completes compression through the coordinated movement of single screw and star wheel, thus avoiding oil participation from the source and completely eliminating the risk of oil pollution.

2. Cleanliness of output gas
ordinary air compressor due to the use of lubricating oil, compressed air may be residual trace oil, through additional filtering equipment to achieve clean standards. The air output by the oil-free air compressor is natural and oil-free, which can directly meet the needs of medical, pharmaceutical, food and other industries that require extremely high gas cleanliness, without subsequent degreasing treatment, simplifying the process.

3. Applicable Scenario Differences
ordinary air compressors are suitable for general scenarios that do not require high gas cleanliness, such as ordinary industrial power drives. Oil-free air compressors are designed for areas with zero tolerance for pollution, such:

• medical equipment air supply (e. g. ventilator, cleaning of surgical instruments);
• pharmaceutical production (e. g. preparation of sterile preparations, sealing of packages);
• food processing (e. g. bottle blowing, nitrogen filling in packaging).

4. Maintenance and operating costs
ordinary air compressor needs regular maintenance of the oil system, replacement of lubricating oil and filter, long-term use of high cost. Oil-free air compressor due to the oil-free design, reducing the wearing parts and maintenance links, more stable operation, lower long-term cost.

Granklin water-lubricated screw air compressor provides an efficient and clean gas solution for enterprises through the oil-free compression technology of single screw plus star wheel, which is the ideal choice for the pursuit of high-quality production environment.
