Is the main reason for the energy-saving air compressor the main engine?
Also consider the pressure loss of some components. For example, you need 8 kilograms of pressure, and if the pressure loss of parts is 0, then you only need to do 8 kilograms of work, but if there is compression, you need to do more than 8 kilograms of work, it will naturally cost electricity.
The energy saving of air compressor mainly depends on the efficiency of the main engine (rotor linetype) and the efficiency of the motor.
