For more than three decades BOGE "Made in Germany" have stood the test of time: in industry and trade - from the one-man workshop to the automotive industry and the large refineries. Today, BOGE have much more to offer than just compressed air: state-of-the-art technology, a modular design concept and maximum energy efficiency ensures that they meet the high reliability and efficiency standards customers have come to expect from BOGE.
Screw compressors are commonly used when large volumes of high-pressure air are needed for industrial projects. They can be seen usually mounted on a trailer at construction sites powering air-operated construction machinery, tools like Jack-hammers and air drills.
The rotary screw compressor has low leakage levels and low parasitic losses vs. Roots type. The supercharger is typically driven directly from the engine's crankshaft via a belt or gear drive. Unlike the Roots type supercharger, the twin-screw exhibits internal compression which is the ability of the device to compress air within the housing as it is moved through the device instead of relying upon resistance to flow downstream of the discharge to establish an increase of pressure.
