ITEM

DESCRIPTION

AOxygen 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 FIO2 must be verified with an Alarmed

Oxygen Monitor / Analyzer.

This Dial does not rotate 360°. The dial starts at 20% or 30% and ends at 100%.

BPrimary Outlet Port

A male DISS oxygen fitting with check valve that delivers flow when engaged to any controlling device, such as a flowmeter.

CAuxiliary Outlet Port

A male DISS oxygen fitting with check valve that delivers flow

when engaged to any controlling device, such as a flowmeter. 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 flows:

Model

Flow Range

High Flow

2

- 100 lpm

Low Flow

0

- 30 lpm

DAuxiliary Bleed Collar

The collar is used to engage and disengage the bleed. The bleed is necessary to maintain accurate FIO2 Concentration below 15 lpm for the High Flow and 3 lpm for the Low Flow. To activate the bleed, slide and rotate the knurled collar back until it contacts the cover. To deactivate the bleed, pull and rotate collar away from cover until bleed flow valve is closed.

EOxygen Inlet Fitting

A female DISS or NIST oxygen fitting with one way valve that is used to connect an oxygen supply hose.

FHeliox Inlet Fitting

A male DISS or NIST heliox fitting with one way valve that is used to connect a heliox supply hose.

GAlarm

An audible alarm that sounds due to an excessive pressure drop or deletion of either gas supply.

HRear Slide Mount with dove tail.
