5.2.3 Exhaust duct design
At the cooling air inlet and exhaust, the machine can only overcome the air resistance resulting
from the duct design. Any additional air resistance will reduce airflow and deteriorate machine cool‐
ing.
➤ Consult the KAESER SERVICE representative before deciding on:
■ Design of the exhaust air ducting
■ Transition between the machine and the exhaust air duct
■ Length of the ducting
■ Number of duct bends
■ Design of flaps or shutters
Further information Further information on the design of exhaust air ducts can be found in chapter 13.3.
5.3 Operating the machine in a compressed air network
If the machine is supplying an air network, the network working pressure may not exceed 16 bar
(China: 15.9 bar).
When charging a fully vented air system there is generally a very high rate of airflow through the air
treatment devices. These conditions are detrimental to correct air treatment. Air quality suffers.
To ensure the desired air quality when charging a vented air network, we recommend the installa‐
tion of an air main charging system.
