One of the world’s leading manufacturers of compressed air treatment equipment, domnick hunter , is offering employers a one-stop breathable air solution that complies with some of the rigorous international regulatory standards relating to such equipment, including BS EN 529:2005.
According to domnick hunter, the new BS EN 529:2005 standard was introduced to provide guidance on the selection, care and maintenance of respiratory protection equipment.
BS EN 529:2005 is one of the new standard in a series of regulatory advances worldwide relating to respiratory equipment. It highlights important 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 comprehensive breathing air range that removes contaminants through an integrated filtration and desiccant dryer package that ensures the pressure dewpoint of the air is sufficiently low enough to prevent liquid water from forming.
A desiccant dryer is essential where catalyst filtration stages are used, and where low ambient temperature is not known. Refrigeration dryers can only be used, where the low ambient temperatures are above 3°C, in heated factory spaces and where no catalyst filters are used.
The new BS EN 529:2005 standard supersedes the existing BS EN 12021:1998 standard, which it references to provide guidance on the actual quality of compressed air to be used for breathing apparatus.
Integral filtration within the domnick hunter range removes contaminants outlined in the existing standard including carbon dioxide, lubricants, odours and tastes. Carbon monoxide is either reduced or completely removed depending on the product model selected.
The range, which runs off a compressed air supply, includes portable systems suitable for a single user to full facility protection. In addition, domnick hunter offers full support and guidance on product selection, system design and testing in accordance with BS EN 12021:1998.
