We offer the most compact, reliable and efficient superchargers on the market combined with simple integration requirements.
Rotrex is the only centrifugal supercharger used in OEM factory fitment production cars, underlining our product’s reliability and performance.
All our superchargers are developed, manufactured, assembled and tested in Denmark.
Rotrex centrifugal superchargers - The superior advantages
Acceleration and power delivery
Compared to traditional centrifugal superchargers, the Rotrex unit offers the highest boost at low and mid-range engine speeds. Compressor speeds as high as 240,000 rpm results in superior acceleration and power delivery.
Reliability
The secret behind Rotrex is the patented planetary traction drive. Smooth planet rollers without sensitive teeth’s gives silent mechanical operation, less vibrations and offer reliability under all types of operations.
Compactness
The compactness and shape of the small Rotrex superchargers offers unique packaging advantages and installation flexibility, an important characteristic in the small modern engine compartment.
Technical specifications
The Rotrex standard product range consists of several family sizes.

Patented technology
Key to Rotrex centrifugal superchargers superior combination of power delivery, compactness and reliability is its patented state of the art traction drive technology.
Great speeds and low mechanical noise are just some of the advantages of traction drives over traditional gear transmissions. Traction drives transmit power through friction forces between its rolling elements.
This traction drive combined with the latest technology in centrifugal compression, characterized by high adiabatic efficiency and low mechanical noise, gives Rotrex centrifugal superchargers an exceptional competitive edge over any other forced induction solution.
