AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B 99
Exhaust air connection
Conduct exhaust air directly into the atmosphere at zero pressure through a
line with a large internal diameter which is as short as possible, or into a gas
discharge line.
Use an exhaust air line of PTFE or stainless steel! The temperature of the
medium can be up to 200 °C! Lay the exhaust air line with a downward gra-
dient.
The inside diameter of the exhaust line should be increased to ≥ 10 mm
within no more than 30 cm from the exhaust outlet. If a very long exhaust air
line is used, it's inside diameter must be much larger than 10 mm; otherwise
the pressure regulation in the gas analyzer may not work properly.
Do not conduct waste air via restrictions or shut-off valves!
NOTE
Dispose of corrosive, toxic or combustible exhaust gases according to the
regulations!
