Here is a very simple and clear English description:
What to Do If an Air Compressor Is Not Energy Efficient
If an air compressor is not energy efficient, first check for air leaks and repair them promptly.
Second, make sure the working pressure is not set too high.
Third, reduce unnecessary idle running time and turn off the compressor when it is not in use.
Finally, perform regular maintenance, such as cleaning filters and replacing worn parts.
These simple actions can help reduce power consumption and improve efficiency.
