The flow through a fully equipped Model 1160 is shown in Figure 1-2. Ambient air is
drawn into the instrument by the internal compressor. It enters a loop where air from the
fan cools the air stream and condenses out water. The water condensate is removed by
the water coalescing filters, and ejected via drains in the rear panel. The membrane dryer
or heatless regenerative dryer further dries the air. The dry air is then routed to the
scrubbers, which remove a variety of pollutants. It then goes to the converter for removal
of CO and VOCs, before passing through a loop to cool the air to room temperature. It
then goes to the pressure regulator and out the rear panel to be used for instrument zero
air, or to provide clean diluent air for span gas systems.
