2 Description
2.1
Product overview
The Dräger PSS
®
3000 Series is a self contained breathing apparatus (SCBA) that
provides the wearer with respiratory protection using an open-circuit, pressure-demand,
compressed-air system. The apparatus can be used as a self-contained system, or with an
independent air supply for supplied-air respirator (SAR) operations. The series is compatible
with a wide range of compressed-air cylinders, face masks and lung demand regulators
(e.g. FPS 7000 and Panorama Nova face masks, Dräger lung demand regulators, and
aluminum or composite cylinders).
2.2
Feature description
The carrying system uses a lightweight polymer-composite space frame (Fig 1, Item 3).
The shoulder straps and waist belt are fully adjustable and use webbing harness straps and
moulded padding on the shoulder pads and waist pad.
The apparatus uses the Dräger high-performance first-stage regulator (6) that reduces
cylinder pressure and supplies breathing air through a medium-pressure hose (5) and
coupling (1) to an attached lung demand regulator. The apparatus is fitted with a mechanical
pressure gauge (4) that incorporates an end-of-service time (EOST) whistle that sounds to
warn the wearer that there is low cylinder pressure (see Section 8 for the EOST activation
pressures). A dual-pressure hose (7) supplies air to the whistle when it is activated, and
has an internal capillary tube that supplies high-pressure air from the cylinder to the gauge.
The air hoses and the first-stage regulator are integrated into the space frame to prevent
snagging and enhance component protection. The hose clips (2) hold the air hoses in
position on the shoulder straps.
Breathing apparatus serial number
The breathing apparatus serial number is on the first-stage regulator.
Compressed-air cylinders, lung demand regulators and face masks
The Dräger PSS 3000 Series is compatible with a single aluminum or composite material
cylinder of 30 to 60 minute capacity, and is available in 2216 psi or 4500 psi versions. Full
descriptions and user instructions are contained in separate instructions supplied with the
cylinder, face mask or lung demand regulator.
2.3
Intended use
The PSS 3000 Series breathing apparatus, when fitted with a cylinder, lung demand
regulator and face mask, is intended for use in applications where a high level of respiratory
protection is required. The assembled breathing apparatus provides the wearer with
