REDUCER/CYLINDER VALVE
CONNECTOR
The combined pressure reducer (20) and
cylinder valve connector (21) reduces high
air-pressure from the cylinder to a medium
pressure of between 5 and 9 bar.
Connection to a cylinder is made by the
threaded hand-wheel on the cylinder valve
connector which locates within the cylinder
valve. Please refer to Section - Replacing Single
Cylinders for further details.
Main components:
29 Connector Hand-wheel
30 Connector O-Ring

DEMAND VALVE (DV)
The DV (12) operates in conjunction with the
exhale valve in the facemask to maintain a
positive pressure within the facemask.
The DV has a reset button that enables wearers
to close the airflow through the DV, allowing
the facemask to be removed without loss of
cylinder air.
When the apparatus is donned the DV is
normally ‘reset’ (closed), and is opened
(activated) when the wearer takes a first breath.

to be used with an airline. The cylinder
provides emergency backup. This can also
act as a Rescue mask attachment - permits
the wearer to supply a rescue mask or an
air-powered resuscitator from own cylinder
air. This reduces the duration of the cylinder
supply.
Split demand valve hose (SDC) - connection on
the hose, permits the DV to be disconnected
from the pneumatics.
Demand valve Y-Piece (Y2C) - acts as a
split demand valve and also provides RSM
functionality.
