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.

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.

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.

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.
