The C38R is the most powerful centrifugal supercharger of the Rotrex standard product range and is available as a clockwise- or counterclockwise-rotating version.
 
Countless number of largescale applications can be boosted by this very efficient and silent unit which supplies air flow up to 0.84 kg/s. Additionally the C38R shares identical packaging and bracketry dimensioning with the C38 range, thereby allowing direct retro-fit for power upgrades of existing kits and installations. Impeller speeds of up to 90,000 rpm are achieved through the patented hi-speed planetary traction drive which combines small size with exceptional performance and durability.
 
The very low noise and vibration characteristic as well as the high efficiency of these superchargers set the industry standard for what is achievable. The C38R range is designed for high performance four stroke gasoline engines with a supercharged output 720kW.
 
For extreme applications where one supercharger is not sufficient, it is possible to use two units to support large amounts of power in a twin-charger configuration. The C38R is also ideal for the supply large amounts of clean pressurized air for other applications such as industrial systems, fuel cell power plants etc.
 
The C38R further pushes the limits of groundbreaking compactness thus maintaining a very flexible supercharger installation particularly on engine applications with tight space and where weight and size are essential. The C38R is available as a clockwise and a counterclockwise version.
 
The supercharger features an integrated dual-action oil pump that works as a dry sump scavenging pump in addition to being the oil supply pump. The self-contained oil system allows flexible positioning of the supercharger on the vehicle and has the benefit of fitting the supercharger without worrying about tampering with the oil system of the engine or any other
 
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 and low Noise
The secret behind Rotrex’s low noise level is the high-tech patented Rotrex rotary drive system. Smooth planet rollers without teeth’s gives silent operation, less vibrations and offer reliability under all types of operations.
 
Compact
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.
