Screw compressors generate compressed air by means of rotating intermeshing spiral rotors. These compressors are often also called screw air ends. Screw compressors are particularly suitable when continuous, consistent pressure is required. These machines are real endurance runners. Screw compressors are often found in industry and trade.
In contrast to piston compressors, screw compressors are still relatively new on the market. Although the principle was developed as early as the 19th century by the German, Heinrich Krigar, the screw compressor did not really gain acceptance until after the Second World War.
Screw compressors are characterized by their relatively small design and low mass. They run quietly an supply compressed air with a very uniform flow. Compared to piston compressors, screw compressors are significantly quieter. This is because there are no high mechanical forces that have to be slowed down or accelerated. The effect: a lower resonance oscillation and therefore less sound.

Screw compressors with manufacturer warranty
RENNER uses only standard components of high quality German manufacturers, to ensure high standard of quality. We reinforce our commitment to the quality of RENNER product by offering a two-year manufacturer warranty. In the unlikely event of a manufacturing defect due to defective material or workmanship we will quickly replace the part.
Energy saving screw compressors with variable speed control
Our screw compressors with variable speed control are designed for tough industrial applications. The intelligent RENNERtronic control and monitoring system ensures that your whole system is well-coordinated. This saves on costs.
Graphic: After 5 years in operation, energy costs amount to 78% of the overall cost of a conventional compressor. The only way to reduce the overall cost is to minimize the cost of energy.
Graphic: Using an RSF compressor by RENNER enables you to save up to 35% of the energy cost. This results in a saving of 25% on overall costs – improving the company’s overall energy balance.
