There are indeed types of air compressors that do not require oil, which are mainly oil-free air compressors. The following is a detailed explanation of the oil-free air compressor:
working principle:
oil-free air compressor is a piston compressor that uses compressed air to directly complete the conversion of gas and liquid in the cylinder without adding any lubricating oil and coolant. Its working principle is basically the same as that of a reciprocating compressor, except that the crankshaft drives the connecting rod to make the piston move linearly (or approximately linearly) during the suction process, and the camshaft drives the connecting rod to make the piston move radially during exhaust. Move and rotate.
Features:
no refueling: oil-free air compressor does not need to add oil during operation, which is its most significant feature.
Maintenance-free: Because there is no oil and related lubrication system, the oil-free air compressor is relatively simple in maintenance, reducing maintenance costs.
Smooth operation: The oil-free air compressor has low noise and low vibration during operation, which improves the stability and service life of the equipment.
Environmental protection: Oil-free air compressors do not produce oil pollution and are environmentally friendly.
Type:
among them, the water-lubricated air compressor produced by Shanghai Granklin Group is one of the commonly used oil-free air compressor types in China. It uses water to lubricate the air compressor head, so there is no need to add lubricating oil.
Advantages:
oil-free air compressor is more energy-saving than traditional air compressor, longer service life, lower noise, low maintenance cost, stable operation, and can work continuously for 24 hours. In addition, it has no pollution to the environment and can be used in high dust environments.
Market situation:
although oil-free air compressors have many advantages, due to their relatively high manufacturing costs, the market penetration rate is not as high as that of traditional air compressors. However, with the improvement of environmental awareness and technological progress, the market demand for oil-free air compressors is gradually increasing.
In short, oil-free air compressor, as a type of air compressor that does not require oil, has significant advantages in energy saving, environmental protection and stability. With the increase of market demand and technological progress, oil-free air compressors are expected to be more widely used in the future.
In industrial production, air compressor as a source of power, its choice is directly related to production efficiency and operating costs. The difference in cost between oil-free air compressor and oil-free air compressor has become an important factor in enterprise decision-making.

In the highly competitive air compressor market, how to choose an efficient, stable and environmentally friendly screw permanent magnet variable frequency screw air compressor has become the focus of many enterprises. Among the many brands, Shanghai Granklin Group, with its excellent technology and high-quality products, wins.
Air compressor plays a vital role in industrial manufacturing, and its role is mainly reflected in the following aspects: Power supply: Air compressor can provide compressed air, which is an important power source. In industrial production, many equipment and tools are needed.
Oil-free and water-lubricated single screw air compressor is a high-end product of air compressor. It provides completely oil-free compressed air and is suitable for industries or fields with high requirements for compressed air quality, such as environmental protection, electronics, chemistry, new energy, textile, papermaking, medical and health, food, aerospace, military industry, etc.
At present, many industries continue to purchase air compressors, which is mainly due to the wide application of air compressors as important industrial equipment and their indispensable role in many production links. The following are some of the main industries that continue to buy air compressors: Machinery Manufacturing: On-machine
Domestic and foreign air compressor manufacturers in the strength of many have been evenly divided. In terms of price, domestic air compressors have more advantages than imported ones,
View detailsIn the pharmaceutical industry, the pressure of compressed air is a key parameter, which directly affects the normal operation of medical equipment and the treatment effect of patients. In general, the pressure range of compressed air in the pharmaceutical industry varies according to the specific needs and application scenarios, but the general
The air pressure of the compressed air in the factory is a dynamically changing value, which is determined according to the specific application scenario, equipment specifications and relevant national standards. The following is a detailed analysis of the compressed air pressure in the factory: 1. common air pressure ranges General applications: For many
Frequency conversion screw air compressor and power frequency air compressor are two common compressed air equipment in the industrial field, each of which has different characteristics and application scenarios. The following is a detailed comparison of these two air compressors: 1. working principle of variable frequency screw air pressure
When choosing a permanent magnet screw air compressor, you cannot rely solely on the brand, but also need to consider the actual needs and budget, so as to choose the appropriate model and specification. Shanghai Granklin Group's water-lubricated air compressors also have a certain share of the market, and its product package.
