inlet stem includes a filter.

A cylinder contents pressure gauge is provided to indicate the cylinder contents (the
medical cylinder valve shut-off valve must be set to the ON position to allow the
pressure to register on the gauge).

GCE regulators can be supplied with a flow-metering device - flow control head “C”
or flowmeter “D”. This function is used to supply a gas flow (l/min) at atmospheric
pressure directly to the patient through the flow outlet “E”, e.g. through a cannula or
a facemask.
The flow outlet “E” can be hose nipple (for cannula or mask) or outlet with thread (for
humidifier).
"
The regulator may be fitted with a pressure outlet. The pressure outlet is the outlet
directly from the low-pressure chamber. Two types of the pressure outlet can be
used:
Pressure outlet I - is fitted with a gas specific medical quick connector also called
“quick coupler” . The user can connect another piece of equipment to this outlet with
a gas specific male probe. The quick connector self seals when the male probe is
disconnected. This outlet is for supplying gas at a controlled pressure to power
medical devices, e.g. medical ventilator.
Pressure outlet II – is fitted with a threaded connector. The regulator with this type of
pressure outlet shall be only an integral part of a medical equipment (e.g.
emergency ventilators, anaesthesia devices, etc.)
•
If the regulator is fitted with two pressure outlets, do not use both of them at
the same time. If you use both of them in the same time the performance of
the regulator will not be according to specification (see appendix 1) !!!
Note also that the product colour (especially flow control knob) might not be gas specific
colour coded.
