Note:
XDS35i can operate with high peak power for 90 seconds before activation of a thermal protection algorithm
which reduces rotational and pumping speed.
The power consumption of the enhanced version at high inlet pressure can be lowered by a further 100 W more with
the installation of a second exhaust silencer by an NW25 T-piece.
