5.2. Components and their Function
The figure on the next page shows a dilution system partially disassembled. One can see the
compressed air connection, marked P
max
8 bar. Below, the toggle switch "On-Off" can be
seen. To the right, the adjustment knob for the pressure control, and right above, the
pressure gauge for indication of the adjusted pre-pressure is located. To the right of the
pressure gauge, the intake opening for the clean air filter can be recognized.
The above-mentioned components, as well as the throttle screw integrated into the cover,
serve the reproducible adjustment and the processing of the clean air which is used for the
dilution of the aerosol.
The inlet nozzle, through which the aerosol to be diluted is sucked in, can be seen on the left
of the picture; the outlet nozzle to which for example the particle measuring instrument is
connected, is shown on the right. Finally, the excess air outlet and the excess air tube
connector can be seen; tubes of 28 mm inner diameter can be connected.
