An air compressor is a machine that compresses air to increase pressure and temperature. They are used in a variety of applications, such as injecting air into tires to obtain the desired air pressure, or compressing oxygen for use in medical devices. Air compressors can be divided into two categories: oil air compressors and oil free air compressors. This article will describe the two types of compressors and their differences.
Oil air compressor
An oil-lubricated Air compressor is a type of compressor that requires the use of lubricating Oil during operation. They contain a lubricating oil tank and a pump to ensure the smooth operation of the equipment. This compressor has low maintenance costs, but requires regular oil changes. They are also less expensive than oil-free air compressors, but are not suitable for use in applications that require high cleanliness, such as in equipment or food processing. The lubricating oil may also remain in the compressed air, which may cause contamination in some applications.
Oil-free air compressor
An oil-free Air compressor is a type of compressor that does not require the use of lubricating Oil. They do not produce poor quality compressed air (due to oil residue) and are used in applications that require a high degree of cleanliness, such as pharmaceutical and food production. Oil-free air compressors are also a kind of high operating cost compressor, because of their complex internal structure and continuous operation of 99% clean air, so their cost is higher than oil air compressors. Although these machines do not require lubricating oil, they do require regular cleaning and maintenance.
distinction
- Use oil or not: oil air compressors use lubricating oil, oil free air compressors do not use lubricating oil at all.
- Scope of application: The oil air compressor price is relatively low, suitable for occasions that do not require high accuracy and cleanliness requirements. Oil-free air compressors are mainly used in industries that require high cleanliness, such as pharmaceuticals, food processing, etc., where clean gases are needed to ensure accuracy and stability.
Maintenance: The maintenance cost of oil-free air compressors is higher than that of oil-free air compressors, because the internal structure of oil-free air compressors is more complex and maintenance is more complicated.
- Health: Oil-free air compressors have a smaller impact on the environment than oil-free air compressors because they do not require the use of lubricating oil and do not produce oil vapors or other harmful gases.
conclusion
The difference between oil-free air compressors and oil air compressors is the oil used and the field of application. Although the cost of using oil-free air compressors is higher, oil-free air compressors are more stable and reliable in situations where a high degree of cleanliness is required. Therefore, when selecting an air compressor, it is necessary to determine which compressor is more suitable for your application scenario according to its use.
