Description

The basic components of the Dräger Life Preserver rescue
vest are the buoyancy control device with outer jacket, hip,
back and leg straps, two air cylinders with attachment adapter
(or two CO
system and pressure relief valve.

The buoyancy control device is partially folded and attached
2
with snap fasteners to the outer jacket. During diving the
buoyancy control device remains folded. In an emergency,
3
when the device is filled, the snap fasteners are opened by the
gas pressure in the air chamber and the vest is inflated fully.

The buoyancy control device contains two brass connection
pieces ultrasonically welded to the air chamber and permits
the use of a dual CO

of two aluminium cylinders with valve. The standard air system
contains cylinders with TÜV approval. Each cylinder supplies
approx. 0.4 litres (liquid content) of air and has an operating
pressure of 200 bar.
The Dräger Life Preserver rescue vest can also be inflated via
a mouth piece and manually operated valve. Air can be
1
released through manual operation of the valve and by holding
the mouth piece above the head. A pressure relief valve keeps
the gas spreading in the Dräger Life Preserver rescue vest at a
pressure of approx. 0.120 to 0.190 bar (1.7 to 2.8 psi) above
the ambient pressure.
The standard straps of the Dräger Life Preserver rescue vest
consist of a hip strap with approx. 50 mm (2 inch) belt width and
a back strap with approx. 50 mm (2 inch) belt width plus two leg
straps with approx. 25 mm (1 inch) wide belting. For possible
