Air flow rates of up to 1000 kg/h are possible.

Fresh gas side
When designing the intake path, the main focus was on high effi-
ciency and capacity. The cross-sections were optimally adapted to
the available space and the air flow was configured to be as direct
as possible.

Intercooler
The greatest pressure losses always occur in the intercooler, which
has been systematically developed and improved in this regard.
The new intercooler is positioned at the lower front end and is,
therefore, fully exposed to the back pressure of the exhaust gases.
Hence, it was possible to maximise the outer cooling air mass flow.
This, in turn, allowed the fins in the intercooler to be configured
favourably.
The total pressure loss along the entire compressed air flow path is
only 135 millibars at maximum flow.
