What is the Difference Between Breathable Air and a Breathing Air System?

Breathing air is a very high quality standard of compressed air as outlined in British Standard BS4275 Guide. The best way to achieve breathing air standard is to pass air through a pre-filter, refrigeration dryer, oil-removal filter, then into a breathing air pack containing a micro filter, carbon filter, desiccant dryer, dust filter and a hopcolite filter.

The air coming out of the breathing air pack will be cleaned of water vapour, oil vapour, carbon dioxide and carbon monoxide. After this process the air is of the highest standard and will pass all breathing air tests to national and international standards.

Breathable air is different and is used by a lot of body shops. The main difference is that breathable air systems often do not have the high quality desiccant dryer. As a result the dewpoint is a lot higher and more moisture is able to pass through into the operatives air mask. The air in this system is considered safe to breathe however it will not pass a BS4275 standard breathing air test.

If you would like to improve your breathing air supply to meet BS4275 standards we can advise, supply and install a suitable system. We can also provide a post-installation breathing air test and issue a breathing air quality test certificate.
