The heart of the air compressor is the screw element, called the air end. The air end is the essential part of any screw compressor. This is the part of the machine where the actual compression occurs, and it is the heart of the screw air compressor.
They are constant flow with variable pressure compressors. This means that at a given speed, they always provide the same amount of air but can be performed at different pressures.
How does the air end work? There are two screws inside the compressor element that rotate in opposite directions. A screw compressor is a “positive displacement” compressor, which means that the air is physically squeezed together under the action of an external force.
In the case of a rotating screw, the air is trapped between the two rotors. The rotor is specially designed to achieve the best efficiency and performance.
