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

respiratory protection for working in contaminated or oxygen-deficient conditions.

The cylinder, lung demand regulator, face mask and other accessories used with this

product must be certified Dräger components, assembled in an approved configuration,

otherwise the operation of the device may be impaired. Contact Dräger for further

information.
