Working Principle

Pneumatic Screw Compressor

The basic principle of a screw compressor is as the male and female rotors are rotating in opposite direction they draw air in between them. As the air progresses along the rotors the air is compressed as the volume space between the rotors decreases, hence creating compressed air that is displace to the outlet.

The following explains the working principle of the Rotary Screw Air Compressor which progressively converts power into potential energy with the help of power or oil engine. As a result, the Air end horizontal screw protector angle actions function efficiently in rare minimal wear and tear with the oil lubrication. Firstly, the atmospheric air is withdrawn inside through the intake valves and the same is repeated. Air is continuously pulled inside through the valves significantly, as a part of the process . Secondly, the drawn air is stored in a air receiver.

To enumerate, the air that exits from the Screw Air end termed as the Displacement. Significantly, the displaced air in which the pressure and volume conversion happens . Following Screw displacement transfers air to the air tank continuously and this displaced air develops pressure inside the air receiver.

Therefore, depending on the volume of pressure the different Rotary Air End different size are categorized as Different pressure and Volume driven by Three phase Electric Motors and Diesel Engine.


Overall, National Equipment Company manufactures varied range of Rotary Screw Air compressors and is suited to fit different requirements. Our wide range of available models markedly suite wider range of customer needs. Our available models include,

  • 5HP/ 7.5 HP/ 10HP/ 15HP/ 20HP/ 25HP / 30HP up to 200HP Rotary Screw Compressors
  • Air storage capacity available in vertical mounted Air Receiver and Horizontal Air Receiver
  • Available Air Tank Capacity starting from 250 liters to 10,000 liters


The Rotary Screw Pneumatic Air Compressors is applicable not only for industrial purposes. The Air Compressor has a flexibility in providing high and controlled pressure and can easily be monitored and controlled, henceforth, making it one of the widely used typology.
