An air compressor is a machine that compresses air and stores it and releases it for use by various equipment and tools. At present, there are two main types of air compressors on the market: air compressors and oil-free air compressors. These two types of air compressors have their own advantages and disadvantages and application occasions, they will be compared and analyzed below.
Definition and rationale
Air compressor: Air compressor is a machine that compresses gas through spiral rotating motion. The basic principle is to continuously inhale, compress and discharge the gas by rotating the spiral cylinder, so as to achieve the effect of increasing the gas pressure.
Oil-free air compressor: In an oil-free air compressor, the compression of gas is accomplished through the interaction of a high-speed rotating blade and a cylinder. The machine does not require the use of any oil lubricants and does not mix oil lubricants into compressed air.
Second, application occasions

Air compressor: Air compressor is widely used in mechanical processing, electronic appliances, food and beverage, printing and packaging and other industries. Due to the high compression efficiency of the machine, it is widely used in the occasions requiring high pressure and high flow.
Oil-free air compressor: Because oil-free air compressor will not mix oil into the compressed air, it is widely used in the painting industry, pharmaceutical industry, food and beverage and other occasions with high requirements for gas cleanliness. In addition, the characteristics of oil-free air compressors such as low noise, no pollution and easy maintenance also make them more and more favored.
Third, energy efficiency
Air compressor: The energy efficiency of air compressor is relatively high, it can provide a large power, and the pressure of compressed air is stable. At the same time, the efficiency of the machine decreases with the increase of service years, and regular maintenance checks are required.
Oil-free air compressor: Because oil-free air compressor does not need to use any oil lubricant, it can truly achieve "zero pollution". At the same time, the power of the machine is less, but it can maintain the output pressure more steadily.
Iv. Maintenance and cost
Air compressor: Because the air compressor is a mechanical equipment, the manpower, material resources and financial costs required for maintenance and maintenance are relatively high. At the same time, the machine needs to replace the oil lubricant regularly, so the operating cost is higher than that of the oil-free air compressor.
Oil-free air compressor: Since the oil-free air compressor does not require the use of oil lubricants, it reduces the maintenance cost of the machine. At the same time, the cleanliness of its output gas can also reduce the cost of gas treatment.
In general, air compressors and oil-free air compressors have their own advantages and application occasions. Air compressors are widely used in situations requiring high pressure and high flow. The oil-free air compressor is more suitable for occasions with higher requirements for gas cleanliness. When selecting the air compressor, the appropriate type of air compressor should be selected according to the specific needs.
