2.4. “Magnetic bell cup” type magnetic air bearing turbine
see RT Nr 6350
The bell cup is rotated by means of a pneumatic motor. Paint is sprayed due to the centrifugal
forces generated by rotation of the bell cup. The higher the rotational speed, the smaller the
particles that are sprayed.
2.5. Shaping air
The air supply circuit can be used to alter the spraying pattern. If the shaping air pressure is
increased, the pattern is narrower and likewise, if it is decreased the pattern is wider.
The shaping air arrives on the turbine side, flows through the holes on outside of the shaping air
assembly and is then directed towards the bell cup.
2.6. Outer cover
The outer air shroud acts as a cover, and also facilitates cleaning of the atomizer.
2.6.1. Rinsing the outside of the bell cup
The solvent flows through a nozzle and uses one
of the openings in the air shroud to rinse the
outside of the bell cup.
2.7. Bell cups
see RT Nr 6285
The bell cup atomises all particle-base paint types . Select the appropriate bell cup according
to the type of product used.
1 Shaping air assembly
2 Bell cup
3 Solvent pipette
