5.2.3 Exhaust duct designAt the cooling air inlet and exhaust, the machine can only overcome the air resistance resultingfrom 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 shuttersFurther 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 networkIf 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 airtreatment 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.➤ Consult KAESER for advice on this subject.5 Installation and Operating Conditions5.3 Operating the machine in a compressed air network40 Operating Manual Screw CompressorASK 901824 12 E
