C30-94 Supercharger

The C30 is a range of centrifugal superchargers with a very versatile application range. Countless
number of medium size applications can be boosted by this very efficient and silent unit which supplies
air flow up to 0.44 kg/s.

Impeller speeds of up to 120,000 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 C30 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 C30 will support engine outputs up to 360kW. Where one
supercharger is not enough, it is possible to use two units to support large amounts of power in a
twin-charger configuration. The C30 can also supply clean pressurized air for other applications such
as industrial systems, exhaust gas after-treatment systems, agriculture applications, fuel cell power
plants etc.

The groundbreaking compact size enables a very flexible supercharger installation particularly on
engine applications with tight space and where 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.
