Does not produce air when the compressor is idle，Within a certain time limit, the fixed speed screw compressor is stopped and started within the set time. When it is necessary to provide varying compressed air, the machine needs to perform a long period of idling to avoid frequent starts and cause overheating.
Although compressed air is not generated during idling, the operation of the fixed speed compressor consumes 70% of the power equivalent to the full load without work. Constant speed compressors operating under dual control (stop/start or online/offline technology) consume only 25% of the full load and can store some energy.
