5.1. The Pneumatic System
Figure 5.1. shows the pneumatic system. Pre-cleaned compressed air is conducted via a
toggle switch to a pressure reduction valve. Via a permanently adjusted throttle and the pre-
pressure indicated at the pressure gauge, the volume flow rate may be adjusted
reproducibly. A filter guarantees sufficiently particle-free air. This particle-free air flows
through the annular nozzle and causes the sucking-in of the aerosol to be diluted. Via the
outlet nozzle, a portion of the diluted aerosol is isokinetically sucked out for further
treatment. The excess aerosol is conducted outside through the excess air outlet.
