Painting data
Painting distance
220 ± 20mm
Typical relative painting speed
0.2 – 0.6m/s
Compressed air – required pressures
Control air for valves
p
dyn
6 – 8 bar
Motor air
p
dyn
= 5,5 – 8 bar
Break air
6 bar
Motor bearing air:
p
dyn
= 5.5 – 7 bar
The motor bearing air may in no case fall below the indicated
minimum pressure. Operating at lower air pressure inevitably leads to
turbine damage.
Shaping air
p

6 - 8 bar
Paint/detergent (brief load)

= 20 bar
Slide medium (short-term load)
p max. = 20 bar
Maximal operating pressure of the shaping air
The shaping air system can be coupled with an inert gas supply for
fire protection. An inert gas supply often works with high pressure.

Risk of damage to property and production disruption
If the maximum allowable operating pressure is exceeded, there will
be considerable damage to the atomizer.
Operate shaping air system with limited pressure only.
Shaping air system for inert gas
max. 10 bar
Maximum operating pressure for shaft detent

Risk of damage to property and production disruption
If the maximum allowable operating pressure is exceeded, there will
be considerable damage to the atomizer.
Operate the shaft detent with limited pressure only.
Control air for shaft detent
max. 6 bar
