C15-20 Supercharger

The Rotrex C15 is an extremely compact centrifugal supercharger. Rotrex C15 is a range of
centrifugal superchargers for large variety of applications where the compactness is one of the
key issues. Countless number of small applications can now be boosted by this very efficient
and silent unit which supplies air flow up to 0.22 kg/s.

Through the patented hi-speed planetary traction drive, the C15 achieves impeller speeds of
up to 201,500 rpm. The exceptional high speeds of the drive give an unsurpassed power to
size ratio compared to any other supercharger on the market.
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 C15 range of superchargers is designed for four stroke gasoline engines. However, two
stroke engines or even diesel engines can benefit from these superchargers with remarkable
results. Depending on the application the C15 will support engine outputs up to 175kW. The
C15 can also supply clean pressurized air for other applications such as exhaust gas aftertreatment
systems, agriculture applications, fuel cell power plants etc.

The groundbreaking compact size enables a very flexible supercharger installation particularly
on engine applications where optimum efficiency as well as weight and size are essential.
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
accessory.

The Rotrex C-type supercharger has been developed and extensively tested with the special
Rotrex traction fluid. To maintain the ultimate level of performance and durability it is very
important that the unit is exclusively run with special Rotrex traction fluid. Make sure the inlet
oil temperature is within the range specified in the table on the next page. Any deviation from
the standard Rotrex oil circuit requires approval from Rotrex.
