One of the differences between compressors is their lubrication. Air compressors are divided into two types in terms of lubrication.
Oil compressor These compressors must be lubricated during operation. In these devices, the available oil should be periodically checked and replaced if needed. An oil pump weighs more because of more parts. The life of this device is also longer. The important point in using these compressors is to be careful in changing the oil. It is better to use only special compressor oil. The oil-free compressor of these compressors is due to the use of special alloys. They do not need oil in their production and they work completely dry. The weight of these devices is less. The efficiency of these devices is better in cold weather and they are suitable for heavy work. Among the applications of these pumps, we can mention their use in repair shops and parking lots.
This model is also called oil-free compressor. These compressors are the newest generation of air compression systems.
Other Compressors
There are other compressors that are not included in this category. For example, auxiliary compressors, vacuum pumps, pressure intensifiers. As the name suggests, pressure intensifiers intensify the pressure in the gas; But the important thing about these types of compressors is that to prevent combustion in them, it is necessary to make sure that there is no oil in them. Industries are used, but due to the high probability of gas ignition in such a state, they are very dangerous in unsafe conditions.
