A rotary screw air compressor is a type of air compressor that works using the principle of rotary displacement mechanism. This displacement is caused by the movements of two pairs of spiral rotors. As they are displaced, a stream of airflow is created. This type of air compressor is mainly used in areas where a large volume of high-pressure air is needed. They are a perfect replacement for the piston compressors. Basically, a rotary screw air compressor operates by trapping a stream of air between its two meshed rotors. By doing so, it reduces the volume of the trapped air, which is moving downwards on the rotor. The reduction of air volume leads to compressed air. This air can be used for large-scale applications. However, they are also applicable to small-scale uses. For a small business, you can get yourself a small screw air pump for sale. The rotary sweeping motion of the rotary screw ensures that there there is a minimal pulsation, spurts or interruptions. In other words, the supply of air will be smooth and consistent. The screw compressor also operates quietly as compared to other types of air compressors. Quite a good percentage of industrial machines depend on the rotary air compressors for their operations. Eliminate this device, and the whole production line will come into a standstill. How a rotary screw air compressor works
