monoxide or an unpleasant smell. It is also possible to use systems to remove or convert
carbon monoxide in order to ensure good breathing air quality.
The maximum permissible
carbon monoxide concentration in the breathing air is 10 ppm (parts per million).
When using a compressor, the air intake must be positioned to prevent the intake of
contaminants, e.g. carbon monoxide and oil components found in exhaust gases. This applies
especially when using portable compressors. For this reason, no vehicles or motor-powered
equipment should be operated in the vicinity of the compressor.
An appropriate filter (e.g. CPF 20, Art. no. 03580I) must be fitted and regularly serviced to
remove unpleasant smells, oil mist, condensation, rust from pipes and other constituents.
We recommend the use of our CMS-2 or CMS-4 carbon monoxide alarm.
5.2 Air volume, pressure and line length
To ensure that the operator is supplied with sufficient oxygen, the air flow
should be between
160 l/min and 200l/min.
The air indicator will be activated by the minimum amount, i.e. the flag will be retracted.
Only CE-approved supply lines with safety couplings should be used to connect the air filter and the
regulating valve (see Section 11: Replacement Parts).
The
length of the line
between the filter and the control valve on the helmet must not exceed 40 m. If it is
necessary to use a longer line, please contact the manufacturer to define suitable measures.
The pressure in the supply line must not exceed 8 bar.
