The Rotrex C15 centrifugal supercharger is the most compact supercharger available. Covering the range of engines up to 2 litres producing up to about 200hp or more on high efficiency engines - the C15 is the perfect choice for small engine applications such as compact cars, motorcycle engines, snowmobiles, quads etc.

Through the patented hi-speed planetary traction drive, the C15 achieves impeller speeds of up to 201,500rpm for the 16 trim and 150,000rpm for the 60 trim. 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.

Applications​

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 from less than 30hp to more than 200hp. Combining two C15 superchargers on one engine will make it possible to reach very high power levels in a vehicle where packaging and space will not allow traditional supercharging with a single large supercharger.

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 is driven by a 7 or 8 ribbed poly V-belt depending on pulley choice. The 7 ribbed pulleys are available in aluminium and the material of the 8 ribbed versions is high strength steel. Pulley diameter ranges from 70 to 90mm in 5mm steps.

The compressor housing can be rotated freely in 60 degree intervals to allow easy adoption to any application.

Oil system​

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 free 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 Rotrex SX100 traction fluid. To maintain the ultimate level of performance and durability it is very important that the unit is exclusively run with SX100 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.
