Operating conditions for instrument air
Supply pressure:

at the gas inlet of the analyzer unit
400 kPa ±20 kPa (4.0 bar ±0,2 bar)(58 psig ±2.9 psig)
Volume flow during
operation:
Standard:
approx. 360 l/h (6 l/min)
Variant:
approx. 1,200 l/h (17 l/min)
Industrial compressed air normally does not meet specifications, can, however,
possibly still be used if it is conditioned:
Use an adsorption drier to remove the air moisture.
Use a catalytic gas purifier to neutralize hydrocarbons.
For precise measurement in the lower measurement ranges
(recommendation):
Condition the instrument air with a catalytic gas purifier.
