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 specific tasks when working on offshore installations are all made more accessible and comfortable when using the Drager PAS AirPack 2.
Increased freedom of movement
The trolley-mounted cylinder(s) provides an uninterrupted air supply to the wearer via a hose reel. As the PAS AirPack 2 can easily be relocated and positioned in a safe zone close to the 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 can 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 unavoidable. The rear wheel of the trolley also incorporates an easy-to-administer foot brake, which prevents any accidental movement of the unit during operation.
It is available with either one or two pressure reducers and two hose reels, allowing joint use of the system or for two completely independent systems to run concurrently. A 50-metre hose length is supplied with Drager PAS AirPack 2 as standard; this can be extended to 100 metres with a range of extension hoses.
The trolley hose reel connector is covered to minimise accidental damage. The hose reel is equipped with a winding handle to allow the hose to be easily rewound onto the reel after use. A braking system also controls outgoing hose distribution 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 successful PSS range of compressed air breathing apparatus. The system incorporates a safety pressure relief valve, and the pressure reducer is shrouded in a protective plate for additional safety.
Pneumatics
The Drager PAS AirPack 2 Trolley module incorporates the following pneumatic elements:
- A pressure reducer is suitable for connecting breathable quality air at an input pressure of 200 or 300 bar.
- Pressure reducer suitable for supplying breathable quality air at an outlet with a medium pressure of 8 bar nominal (6 to 10 bar).
- Vent valves allow for the independent charging of an individual cylinder.
- High Pressure (HP) gauge, indicating cylinder pressure.
- Medium Pressure (MP) gauge, indicating cascade system or ring main pressure.
Safety features
- Use a 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 independent airline source use. The cascade system or ring main pressure is indicated at approximately 4.5 bar.
- Suitable for use in explosive atmospheres (ATEX Zone 1).
Performance
The high-performance pressure reducer assembly of the Drager PAS AirPack 2 is incorporated in the main pneumatic manifold assembly 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 medium-pressure airline system.
