Does the air compressor need to be turned off when the cold dryer is turned off?

It is recommended to close, and the shutdown sequence is exquisite.

The working principle of the cold dryer is to rely on the gas flow to cool down and remove water. After the air compressor is turned off, there is no gas flow in the pipeline, and the cold dryer is idling, which is not only meaningless, but also may hurt the parts due to changes in internal pressure.

Water lubricated air compressor in this matter more attention. Because the water itself participates in the compression when it works, the residual water in the pipeline after the shutdown is much more than that of the ordinary air compressor. If the water is left in the cold dryer, it will easily accumulate inside for a long time, and may be brought out when the machine is turned on next time, which will pollute the trachea instead.

The correct approach is to turn off the air compressor first, wait for the pressure in the pipeline to slowly drop, and then turn off the cold dryer. When starting up, turn on the cold dryer first to preheat it stably, and then turn on the air compressor. In this way, the cold dryer always works in a state of airflow, which is not easy to cause problems, and the air pipe can be kept clean.

The simple note is: when the cold dryer is turned on, the air compressor is turned off.
