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.

动不冲击电流变频器本身涵盖了软启动的功能，启动电流最大在额定电流的2倍以内，启动冲击很小。工频启动一般在额定电流的6倍以上，当工厂电网容量有限时，会引起空压机开关跳闸。不仅是对电网的，对整个机械系统的冲击，也大大减少。
The dynamic and non impulse current converter itself covers the soft start function. The maximum starting current is within 2 times of the rated current, and the starting impulse is very small. Power frequency startup is generally more than 6 times of rated current. When the power grid capacity of the plant is limited, the air compressor switch will trip. It is not only to the power grid, but also to the whole mechanical system.
可变流量控制普通的工频空压机只能工作在一个排气量，而永磁变频空压机可以工作在排气量比较宽的范围内。根据实际用气量实时自动调节电机转速，控制排气量。用多少气产多少气，用气量低时还可以让空压机自动休眠，大大减少能源的损失。
Variable flow control common frequency air compressor can only work in one exhaust volume, while permanent magnet variable frequency air compressor can work in a wide range of exhaust volume. According to the actual gas consumption, the motor speed is automatically adjusted in real time to control the exhaust volume. How much gas to use to produce how much gas, low gas consumption can also let the air compressor automatically sleep, greatly reducing the loss of energy.
