3 Description
3.1 Feature description
The PSS® AirBoss Agile is a breathing apparatus that provides the wearer
with respiratory protection using an open-circuit, pressure-demand,
compressed-air system. The product includes a TX Gauge and is
compatible with Dräger compressed air cylinders, masks and lung demand
valves.
3.1.1 Carrying system
The carrying system has a carbon-composite backplate, with adjustable
shoulder straps and waist belt connected using quick release connectors.
Some variants feature an adjustable backplate where the height can be
changed to one of three preset heights to suit the body length of the wearer
(short (S), medium (M) and long (L)). The waist pad is connected at a
flexible joint to compensate for the twisting and bending of the user.

Pneumatic hoses and other modular components are integrated into the
backplate to prevent snagging and to enhance component protection.
Universal accessory clips (Fig 1, Item 7) can be fitted to the shoulder and
waist pads.
3.1.2 Pneumatic system
The breathing apparatus uses a Dräger high-performance pressure
reducer (Fig 1, Item 5) that reduces cylinder pressure. Breathing air is
supplied through a medium-pressure hose (6) and coupling (2) to the
attached lung demand valve (3). A pressure relief valve will activate and
vent air to the atmosphere at the pressure reducer (Fig 2) if the medium-
pressure increases to 11–16 bar. High-pressure air is supplied through an
internal capillary inside the dual-pressure hose (Fig 1, Item 4) to the
gauge (1). Air is also supplied through the dual-pressure hose to the
warning whistle (8) when the pneumatic pressure is low.
3.1.3 TX Gauge
The TX Gauge (Fig 3) is a mechanical pressure gauge with a warning
whistle and photoluminescent gauge face (Fig 3, Item 3). The gauge face
can be illuminated for approximately 3 seconds by a white LED located
around the gauge face by pressing the illumination button (Fig 3, Item 1).
Green (Fig 3, Item 2), amber (Fig 3, Item 4), and red (located around the
gauge face) LEDs give visual signals to the user.
The visual signals provided by the TX Gauge are shown in the following
table.
The TX Gauge switches on automatically when the cylinder valve is
opened if the following conditions are met:
– The pressure in the compressed air cylinder is approximately 10 bar or
greater.
The TX Gauge has radio frequency (RF) communication circuitry that
allows:
– Reading and reprogramming of the TX Gauge
– Wireless transmission of data to compatible devices
– Pairing of the TX Gauge with other compatible devices
Information that can be read from the TX Gauge includes device identity,
a record of events (datalog), the current values for configurable
parameters and the firmware version. Configurable parameters include
intermediate pressure warning activation pressures, gauge illumination
duration, etc. The parameters described in this document are the default
for the device. Reading and reprogramming of the TX Gauge requires
Dräger PC Link. Contact Dräger for details.
The TX Gauge has a short range RF wireless transmitter. This transmitter
can transmit data (such as switch on/off signals, pressure values, etc.) to
compatible devices (e.g. the FPS® 7000 HUD (head-up display)) that are
within communication range. See the device instructions for use or contact
Dräger for details.
The TX Gauge can be paired with compatible removable integrated Dräger
personal alert safety system (PASS) devices. Pairing ensures that the
PASS will only respond to signals transmitted by the paired TX Gauge, and
will ignore switch on/off signals transmitted from any other devices in
range. More than one PASS device may be paired with a single TX Gauge.
To check for paired devices within range, press and hold the illumination
button for 10 seconds. See the PASS device instructions for use or contact
Dräger for details of pairing the TX Gauge.

training establishments etc.), reduce the overhaul period for the
pressure reducer. In these circumstances, Dräger recommend that the
overhaul frequency should be less than 5 000 applications of use. An
application of use is defined as a single use of the fully assembled
breathing apparatus, where the user breathes from the air cylinder. It
does not include system pressurization for pre-operational checks.
