Version 3.0 4
1. Objectives, field of application and
conditions for use
The abrasive blasting helmet is used in a working environment where protection of
the respiratory organs, face and head is required against ricocheting medium, particles,
mists, vapours and gases.
The abrasive blasting helmet should be connected via CONTRACOR® Breathing Air
Hose to the compressed air system which supplies breathing air according to EN 12021.
The required airflow can be adjusted on the regulator. The integral airflow indicator displays
whether sufficient air is passing into the helmet. The disposable glass visor fitted against the
helmet window can be removed when polluted or damaged. To remove, open the frame.
1.1. Limitation of usage
• The system is not suitable for working in areas with: intense heat radiation, open fires,
risk of explosion or if extremely high concentrations of hazardous matter, causing
immediate health risks, are present.
• If the ambient temperature is below the freezing point, the humidity in the compressed
air circuit can result in icing-up of coupling or regulator, blocking the further supply of
air. In such a case it is necessary to ensure that the humidity content in the compressed
air (at atmospheric pressure) is less then 50 mg/m
3
, and in accordance with EN 12021.
Standard compressed air circuits do usually not comply with this requirement.
• If applicable, the letter «F» indicates that the helmet and the compressed air supply
hose can be used in the flammability danger zone.
WARNING!
Abrasive blasting helmet CONTRACOR® ASPECT should be connected only
to a compressed air system that delivers breathing air according to the
European norm EN 12021.
When using the helmet in non-EU countries all local norms and laws for the
breathing air supply have to be observed.
