Rotrex Supercharger C38R-122

The C38R are the most powerful centrifugal superchargers in the Rotrex standard product range
and are available as a clockwise- or counterclockwise-rotating version. Countless number of
large-scale applications can be boosted by these very efficient and silent units which can supply
air flow up to 1,1 kg/s. Additionally the C38R shares identical packaging and bracketry
dimensions 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 940kW. 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 ground-breaking 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 superchargers feature 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
accessory.
