Breathing air standards
April 1st 2006

British Standard BS EN 529:2005 was recently introduced to provide guidance on the selection, care and maintenance of respiratory protection equipment. It supersedes BS4275:1997.

The new standard highlights changes in the quality of breathable air from a compressed air source and states that purification stages must be used to remove water droplets and vapour, oil mist, odour and particulate.

domnick hunter offers a breathing air range that removes contaminants through an integrated filtration and desiccant dryer package to ensure that the pressure dewpoint of the air is low enough to prevent liquid water from forming. The range includes portable systems suitable for a single user to full facility protection.
