9. MAXIMUM DRYER INLET AIRFLOW CORRECTION
The nominal inlet flow specified in the table with technical specifications corresponds to the following
operating conditions:
Working pressure 7 Bar(g)
Inlet air temperature
100°C
Moisture content in inlet air
Absolute moisture content 27.5 g/m
3
at 0 Bar(g)
This corresponds to a compressor drawing in air
with a temperature of
30°C and relative humidity
of 90% at normal atmospheric pressure
Ambient temperature
30°C
At other operating conditions, maximum dryer airflow (Q
m
) is calculated using the nominal flow
shown above in the technical specifications (Q

) and a combination of correction factors k

10. OUTLET AIR PURITY
Based on the accessory filtration that is used (Chapter 7), the following outlet air purity levels can
be achieved (expressed as A.B.C purity classes, where A is the purity class for the particulate, B is
water vapour content and C is oil content pursuant to ISO 8573-1:2010).
