Fixed-Speed Compressor

1.Structure and Cost: The structure is relatively simple, without the need for a complex Variable Speed Control System. The initial purchase cost is low, and maintenance is easy (fewer components and fewer fault points).

2.Operational Stability: In scenarios where the load (air demand) is stable, the operating state is stable, mechanical wear is uniform, and reliability is high.

3.Energy Consumption Characteristics: Energy consumption is relatively fixed. Due to the non-adjustable speed, even if the air demand decreases, the motor still operates at the rated speed (still consuming about 30%-50% of the rated power during unloading), resulting in poor energy efficiency. Especially in scenarios with large load fluctuations, energy waste is obvious.

It is suitable for small and medium-sized scenarios with stable air demand and low requirements for energy saving, such as small processing plants, maintenance workshops, laboratories, etc. In these scenarios, the fluctuation of air pressure and flow is small, and the "loading-unloading" cycle is infrequent, so the advantages of low cost and easy maintenance of fixed-speed air compressors can be fully utilized.
