COMPONENT DESCRIPTION
ITEM DESCRIPTION
A
Oxygen Concentration Dial
A dial used for selecting oxygen concentrations between 20%
-100% or 30% -100%. The FIO2 scale is used for reference
only. The actual F
IO2 must be veried with anAlarmed
Oxygen Monitor / Analyzer.
This Dial does not rotate 360°. The dial starts at 20% or
30% and ends at 100%.
B
Primary Outlet Port
A male DISS oxygen tting with check valve that delivers ow
when engaged to any controlling device, such as a owmeter.
C
Auxiliary Outlet Port
A male DISS oxygen tting with check valve that delivers ow
when engaged to any controlling device, such as a owmeter.
This outlet is equipped with a bleed valve that allows the user
to control if the bleed is ON or OFF. With the bleed in the “ON”
position, this outlet delivers accurate oxygen concentrations
in the following ows:
Model Flow Range
High Flow 2 - 100 l/min
Low Flow 0 -
30 l/min
D
Auxiliary Bleed Collar
The collar is used to engage and disengage the bleed. The
bleed is necessary to maintain accurate
FIO2 Concentration
below 15 l/min for the High Flow and ≤ 3 l/min for the Low
Flow. To activate the bleed, slide and rotate, (if applicable) the
knurled collar back until it contacts the cover. To deactivate the
bleed, pull and rotate, (if applicable) collar away from cover
until
bleed ow valve is closed.
E
Oxygen Inlet Fitting
A female DISS or NIST oxygen tting with one way valve that
is used to connect an oxygen supply hose.
F
Heliox Inlet Fitting
A male DISS or NIST heliox tting with one way valve that
is used to connect a heliox supply hose.
G
Alarm
An audible alarm that sounds due to an excessive
pressure drop or deletion of either gas supply.
H
Rear Slide Mount with dove tail.
