C38-81 Supercharger

The C38 is the second most powerful centrifugal supercharger of the Rotrex standard product range.
Countless numbers of large scale applications can be boosted by this very efficient, reliable and silent
unit which supplies air flow up to 0.63 kg/s.

Impeller speeds of up to 90,000 rpm are achieved through the patented high-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 C38 range is designed for four stroke gasoline engines with a supercharged output up to 530kW.
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 C38 is also ideal for the supply of clean pressurized air for
other applications such as industrial systems, fuel cell power plants etc.

The ground-breaking 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.
