空压机就是空气压缩机。主要是用来压缩空气的机械产品，在很多地方都会用到。比如空压机的一个最常用的功能是能够将空气进行压缩从而用作动力，在电力行业运用比较广泛。除此之外还可以用来制冷和分离气体，输送气体等等作用。在生活和工作中发挥着非常重要的作用。
An air compressor is an air compressor. It is mainly used for mechanical products of compressed air, which will be used in many places. For example, one of the most common functions of the air compressor is to compress the air and use it as power, which is widely used in the power industry. In addition, it can also be used to cool and separate gas, transport gas and so on. It plays a very important role in life and work.
而压缩机则是总称。且压缩机有铜钟 一次性止血带 标志桩模具 钢丝轮 流水槽模具 防撞墙模具 检查井钢模具 不锈钢铸件 模锻件很多种类，如冷媒压缩机、氢气压缩机和空气压缩机等等。空气压缩机只是压缩机中的一种，它的压缩媒介是空气，而压缩机可以用来压缩很多东西，不仅仅是空气。因此，空压机和压缩机的区分，就像是中国人和人类一样。中国人是包含在人类这个范畴中的，空气压缩机被包含在压缩机这个总概念中，是压缩机中的一种。
Compressor is the general term. And there are many kinds of compressors, such as refrigerant compressor, hydrogen compressor, air compressor and so on. The air compressor is only one of the compressors. Its compression medium is air, and the compressor can be used to compress many things, not just air. Therefore, the distinction between air compressor and compressor is just like that between Chinese and human. Chinese people are included in the category of human beings. Air compressor is included in the general concept of compressor, which is a kind of compressor.
