2.1.2 Noise level
Measurement conditions
Measuring-surface sound-pressure level as per
EN ISO 3744, measured at a distance of 1 m
[3.28 ft] at an operating point of approximately
2/3 of the permissible total pressure difference
with the lines connected without a vacuum or
pressure relief valve, tolerance


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.
