ELSA DASH/SPRINT
4
The hood design changed in October
1998, however, the instructions for
use are the same for both hoods.
Both hood types have an inner mask
to minimise visor misting and carbon
dioxide dead space. A spring-loaded
exhale valve helps maintain a positive
pressure within the facepiece.
Hoods are fabricated from high-
visibility, flame resistant materials
with a rubber neck seal.
The new hood is available as a
standard version and as an EZ Clean
version, fabricated from a more
durable material.

moulded in non-dermatitic material
and can be supplied with five point
elastic, or Neoprene head harnesses.

2.4 REDUCING VALVE
(DASH/SPRINT)
The reducer is a simple, automatic
spring and piston device, which
screws into the charging adaptor of
the cylinder valve and must be
removed to charge the cylinder. It is
attached to the cylinder using the
handwheel.
It provides an output pressure of
between 5.5 and 9.5 bar with a
maximum flow rate of 300 L/min.
The medium pressure system is
protected by a pressure relief valve
(PRV) located in the reducer which
opens when pressure in the reducer
rises above 9.5 bar.
