Compressed air
Quality of the compressed air
Motor bearing air
according to ISO 8573.1:2010
Driving air
according to ISO 8573.1:2010
Brake air
according to ISO 8573.1:2010
Shaping air
according to ISO 8573.1:2010
Purity classes ISO 8573-1:2010
1:4:1
Limitations for purity class 4 (pressure dew point max.):
-
≤
-3 °C @ 7 bar absolute
-
≤ +1 °C @ 9 bar absolute
-
≤ +3 °C @ 11 bar absolute
Consumption of the turbine
Motor air
100 – 730Nl/min
Motor bearing air
60 Nl/min
The motor bearing air pressure must not drop below the specified
minimum pressure. Operating at lower air pressure inevitably leads to
turbine damage.
Shaping air consumption
Shaping air 1
max. 450Nl/min
Shaping air 2
max. 440Nl/min
Shaping air when rinsing the atomizer
200 – 400Nl/min
Shaping air when cleaning
80 – 100Nl/min

Starting Operations
The module may only be started when fully assembled. Before
commissioning, ensure that there are no loose parts, such as tools or
cleaning agents (cloth), in the module or in the cabin.
6.4.1
Commissioning notes
The following checks should be performed:
- Is the atomizer properly mounted? (See chapter "Installation.")
- Are all the hoses to the atomizer and its upstream components free
of impurities?
For this purpose, the air ducts and, where appropriate, the material
lines are to be blown free before assembly.
