Minimum Dental Air Quality Required
Although not legislated for in Australia, the Standard that should be adopted as a minimum
requirement for Dental Air is ISO 8573-1: 2001 Quality Class 1.4.1
This is more stringent than the (now withdrawn) Australian Standard for Dental Compressed Air.
AS 2866-1986 “Dental equipment - compressed air systems”.
This air quality level should be adopted as a duty of care by the dentist to their patients
and staff and is the minimum level of air quality recommended by us, as our duty of care to our
The most significant aspects of this air quality standard are the three contaminant components
nominated, they are particulate matter, water vapour and condensed hydrocarbons. There is also the additional
consideration of odour to be take into account.
Particulate Matter – should not exceed 0.01
Water Vapour – should not exceed a pressure due point
of 3 deg. C
Condensed Hydrocarbons – should not exceed 0.01 mg /
Odour – There should be no noticeable
The pressure due point (P.D.P) is the temperature at which moisture begins to condense in a
compressed air system.
