(Drager Brand Airline breathing equipment Model PAS Airpack 2 Trolley)

Drager Brand Airline breathing equipment Model PAS Airpack 2 Trolley

Description

Designed using leading technology and materials, Drager’s range of heavy duty airline apparatus is ideal for

use where an extended duration of breathing air is called for.

Chemical tank cleaning, toxic spillages or certain tasks when working on offshore installations are

all made easier and more comfortable when using the Drager PAS AirPack 2.

INCREASED FREEDOM OF MOVEMENT

Uninterrupted air supply is provided by the trolley-mounted cylinder(s) to the wearer via a hose reel.

As the AirPack can easily be relocated and therefore positioned in a safe zone which is in close proximity to working area,

the user only needs to wear a lightweight harness, such as Drager’s PAS Colt, during operation.

This allows the wearer a greater freedom of movement, and less stress and fatigue than they would be subjected to if wearing

a conventional self-contained breathing apparatus unit.

A WELL THOUGHT THROUGH SYSTEM

The Drager PAS AirPack 2 is able to accommodate one or two compressed air cylinders of up to 50 litres in capacity and

is constructed from an anti-static powder coated steel material.

The unit can be supplied with a fully approved lifting eye, enabling safe transfer when elevated working areas may be unavoid able.

The rear wheel of the trolley also incorporates an easy to administer foot brake, which prevents any inadvertent movement of the unit during operation.

It is available with either one or two pre s sure reducers and two hose reels allowing joint use of the system or for two completely

independent systems to run concurrently.

A 50 metre length of hose is supplied with Drager AirPack 2 as standard,

this can be extended to a length of 100 metres with a range of extension hoses.

The trolley hose reel connector is protected with a cover to minimise inadvertent damage being caused.

The hose reel is equipped with a winding handle to allow the hose to be easily re-wound onto the reel after use.

Out -going hose distribution is also controlled with a braking system in order to prevent unnecessary unwinding and potential entanglement.

The Drager PAS AirPack 2 benefits from the world renowned,

tried and tested pneumatics system used on Drager’s suc cessful PSS range of compressed air brea thing apparatus.

The system incorporates a safety pressure relief valve and the pressure reducer is shrouded in a protec – tive plate for additional safety.

Pneumatics

The Drager AirPack 2 Trolley module incorporates the following pneumatic elements:

Pressure reducer suitable for connec – ting breathable quality air at an input pressure of either 200 or 300 bar.

Pressure reducer suitable for supply – ing breathable quality air at an outlet medium pressure of 8 bar nominal (6 to 10 bar).

Vent valves, to allow for the indepen dent charging of an individual cylinder.

High Pressure (HP) gauge, indicating cylinder pressure.

Medium Pressure (MP) gauge, indi ca ting cascade system or ring main pressure

Performance

The high performance pressure reducer assembly of the Drager AirPack 2 is incorporated in the main pneumatic

manifold assembly located behind the control panel.

Functioning at inlet pressures of 200 or 300 bar the reducer provides a controlled outlet operating medium

bar-pressure supply of 8 bar nominal (6 to 10 bar).

A pressure relief valve, incorporated into the manifold, ensures that any ‘over pressure’ (possible failure

of the reducer) will not enter the mediumpressure airline system.

Safety features

Pressure relief valve, to relieve medium pressure from air hoses.

Whistle Warning Unit – High pressure (HPWWU), indicating cylinder pressure to a volume of approximately 55 bar

Whistle Warning Unit – Medium pressure (MPWWU) for use with independent air line source.

Indi cating cascade system or ring main pressure at approximately 4.5 bar.

* Units equipped with the Quick Release Coupling will need to purchase the Lung Demand Valve separately
