CEN-PAQ
5
When the apparatus is donned, the DV is
normally “reset” (closed) and is opened
(activated) when the wearer takes a first
breath.
The DV has a supplementary flow device
(bypass), that the wearer can open using
the bypass knob.
When the bypass is used the unregulated
flow of air through the DV reduces
cylinder duration.
The DV is connected to the facemask by
a Quick-Fit (QF) bayonet fitting with a
spring-loaded locking catch to prevent
accidental disconnection.
2.4 FACEMASK
CEN-PAQ is approved for use with the
PanaSeal facemask. The PanaSeal
facemask is made from non-dermatitic
materials and is available in either black
neoprene or blue silicone and is retained
using a fully adjustable five-point head
harness.
The mask is approved to EN 136 for use
with positive pressure breathing
apparatus.
A speech diaphragm aids
communication.
The mask incorporates an inner mask
that reduces carbon dioxide 'dead space'
and prevents visor misting.
The polycarbonate visor meets the
requirements of EN 136, Part 10, for
impact resistance and optical clarity.
A version of the PanaSeal facemask is
also available for use with the Gallet
TM
helmet.
For airline equipment, the maximum
allowable length of supply hose is 90
metres.
