2.1.3 Temperature increase
The information listed in the following tables
corresponds to the heating of the side channel
housing and the air exiting compared to the
ambient temperature during operation with a
permissible total pressure difference and an air
pressure of 1013 mbar [14.7 psi]. At lower air
pressures these values increase.
