6.1. Compressed Air Cylinders
Danger!
When handling compressed air cylinders, observe the relevant
operating manual and the safety instructions specified in it.
Improper handling of compressed air cylinders can have fatal
consequences for you and others.
6.1.1. Compressed Air Cylinders
The compressed air breathing apparatus is compatible with a large number of
different compressed air cylinders (
Section 7.3). The MSA compressed air
cylinders are made of steel or carbon fibre compound (composite). They are type
approved and in accordance with the respective standards.
Applicable national regulations must be observed.
The cylinders must be ordered separately. Protective covers are available for all
6.0 l and 6.8 l composite cylinders. (
Section 7.4).
6.1.2. Valves
The cylinder valves that screw into the cylinders are type approved according to
EN 144. The handwheels are protected against impacts. They must be fully open
for use. The ratchet valve can be closed only by additionally pulling the
handwheel. This prevents it from closing accidentally.
6.1.3. T-Pieces
The T-pieces allow two compressed air cylinders to be connected to the
compressed air breathing apparatus. Depending on the cylinder size, different T-
pieces must be used, e.g. the 4l/200 bar steel cylinders require
∅
115/200 bar T-
piece; the 6l/300 bar or 6.8l/300 bar composite cylinders require the
∅
156/300 bar T-piece. T-pieces must be ordered separately (
Section 7.4).
6.2. Lung Governed Demand Valve / Full Face Mask
The base units of the AirMaXX series are provided for use with various MSA lung
governed demand valves and full face masks. A list of compatible devices is
given under Section 7.2.
