The difference between micro-oil air compressor and oilless air compressor

The core difference between micro-oil air compressor and oilless air compressor

1. Lubricating media and working principle

• Micro-oil air compressor: Traditional lubricating oil is used as cooling, sealing and lubricating medium. The oil system participates in the compression process, and the lubricating oil needs to be replenished or replaced regularly.
• Oil-free air compressor (such as Granklin air compressor): Lubrication and sealing are completed by water or other non-oil media, completely eliminating the need for lubricating oil to participate in the compression cycle. Granklin adopts a single screw and star wheel structure to achieve efficient sealing and component lubrication using water as the medium.

2. Compressed air cleanliness

• Micro-oil air compressor: The exhaust may contain trace amounts of oil, which needs to be further purified through a rear filter element. It is suitable for conventional industrial scenarios that are not sensitive to oil.
• oil free compressor: The oil content in the exhaust is close to zero, and no additional oil removal equipment is needed. It can directly meet the needs of high-clean industries such as medical, food, and electronics.

3. Maintenance and environmental protection

• Micro-oil air compressor: The oil system needs to be maintained regularly and waste oil is processed, which poses a risk of oil pollution.
• oil free compressor: No oil circuit design, simplified maintenance, and no waste oil is generated, which is more in line with environmental protection requirements. Granklin water lubrication technology achieves long-term stable operation through a circulating water system, further reducing maintenance costs.

4. applicable scenarios

• Micro-oil air compressor: Suitable for general manufacturing, construction sites and other scenarios with low air quality requirements.
• oil free compressor: Designed for areas that require pure compressed air, such as medical equipment, precision manufacturing, laboratory analysis, etc. Granklin air compressors can provide reliable solutions for such scenarios.

summary
Oil-free air compressors achieve complete oil-free compression process through technological innovation (such as Granklin’s water-lubricated single screw technology). They have significant advantages in cleanliness, environmental protection and maintenance convenience, and are especially suitable for use in industries with stringent air quality requirements. Micro-oil air compressors meet conventional industrial needs with cost-effectiveness and applicability.
