永磁变频空压机的最大特点就是节能。一般节能效果达到8%及以上。主要视工作工况和变频器的参数而定，当客户的用气压力不稳定，波动幅度较大，其节能效果就越好。
The biggest characteristic of permanent magnet variable frequency air compressor is energy saving. The general energy saving effect is 8% or more. It mainly depends on the working conditions and the parameters of the frequency converter. When the gas pressure of the customer is unstable and the fluctuation is large, the energy saving effect is better.
气压稳定由于变频化的螺杆空压机利用了变频器的无级调速特点，通过控制器或变频器内部的PID调节器，能平缓启动，对用气量波动比较大的场合，又DG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具能快速调节响应。
The air pressure is stable because the variable-frequency screw air compressor makes use of the stepless speed regulation characteristics of the frequency converter. It can start smoothly through the controller or the PID regulator inside the frequency converter, and can adjust the response quickly when the air consumption fluctuates greatly.
主机与电机一体轴式传动效率100%，无需联轴器、无需齿轮、无需皮带传动。永磁电机无需轴承，不用维护保养，不用添加润滑剂，消除故障点及降低保养成本，普通异步电机常常出现轴承磨损导致烧线圈等故障，维修成本高。
The transmission efficiency of the main engine and the motor is 100%, without coupling, gear and belt. Permanent magnet motor does not need bearing, maintenance, and lubricant, so as to eliminate the failure point and reduce the maintenance cost. The common asynchronous motor often has bearing wear, resulting in coil burning and other failures, which leads to high maintenance cost.
