➤ Consult the KAESER service representative before deciding on:
■ the design of the exhaust air ducting
■ the intersection between the machine and the exhaust air duct
■ the length of the ducting
■ the number of duct bends
■ the design of flaps or shutters
Use only motorized ventilation flaps and louvers on variable frequency drive (SFC) machines.
Flaps or louvers that open through the pressure of the airflow against the force of gravity do not
open sufficiently at low cooling fan speeds.
Further information Further information on installation of exhaust air ducts can be found in chapter 13.3.
5.3 Using the Compressor to Supply A Compressed Air System.
When the machine is connected to a compressed air system, the system operating pressure must
not exceed 232 psig.
Initial filling of a fully vented air network generally creates a very high rate of flow through air treatment
devices. These conditions are detrimental to correct treatment. Air quality suffers.
To ensure maintenance of desired air quality when filling a vented compressed air system we rec‐
ommend the installation of an air main charging system.
