MSA AirElite 4h
6
Description
GB
Above the air distributor (9) is the breathing bag unit with an inhalation bag (7), an exhalation bag (5)
and the surplus valve (3). A class P2 particle filter (8) to EN 143 is fitted on the air inlet side of the inha-
lation bag.
The valve control (18) connects the breathing hose assembly (15) to the inhalation bag and exhalation
bag. The blower (19) and the sensor assembly (16) are attached to the valve control.
On the intake side, the blower is connected to the exhalation bag and on the outlet side with the air
distributor. The sensor assembly provides data for calculating the residual capacity.
The automatic choke, the blower, the quick starter, the sensor assembly, as well as the monitoring unit
and control monitor IC-Air (6), are supplied with energy by the battery (1). The battery can be recharged
via the charging jack (4) using the battery charger for AirElite 4h batteries (order no. 10068542). Alter-
natively, the use of non-rechargeable batteries is possible.
The breathing hose assembly is protected from damage by a flash-over protection. It is connected to
the valve control of the device. The breathing hose assembly is attached to and lead sealed in a socket
on the left-hand shoulder harness. When removing the breathing hose assembly from the socket an
electrical contact triggers an autostart which puts the device into operation.
Above the breathing bag unit is the electronic distributor (2) with connections for the IC-Air, the auto-
start, the blower, the sensor assembly and the battery. The connections to the distributor are identified
by symbols and colored markers.

The device can, alternatively, be used with chemical canisters for operating times of up to 4 hours (at
a breathing minute volume of 30 l/min) or with chemical canisters for operating times of up to 2 hours
(at a breathing minute volume of 40 l/min). For training with the AirElite 4h are either ambient air depen-
dent training canister (with non-interchangeable housing cover) or KO2 training canister for ambient
air independent exercises up to 2 hours (at a breathing minute volume of 40 l/min), also with a special
non-interchangeable housing cover, available.
The electronic control of the IC-Air identifies the type of canister being used automatically, displays it
and calculates the percentage residual capacity accordingly.
The full face masks 3 SR AirElite, Advantage AirElite or Facepiece G1 AirElite are available as options
(see the operating manuals for the full face masks).
CAUTION!
The AirElite 4h is a device for gaseous atmospheres. It must not be used for diving.
