Supply and Breathing Air Specifications

All  supply  and  breathing  air  must  meet  the  following  requirements  of  CGA  G-7.1-1997.    Supply  air
delivered to the Membrane System must be purified to meet Grade D or E quality, and periodic air
quality  testing  to  assure  compliance  is  recommended.    All  breathing  air  for  diving  produced  by  the
downstream compressor must be purified to meet Grade E quality, and periodic air quality testing to
assure compliance is mandatory.

(2) Supply air delivered to the Membrane System must contain <0.003 PPM Oil Vapor

All breathing Nitrox produced for diving must be purified to meet these same requirements, except for
oxygen content. Nitrox oxygen content must measure /- 1% O

of the specified value of the

mixture using a properly calibrated Oxygen Analyzer (i.e. Nitrox produced with a target content of
32% O

2

must measure in the range of 31-33% O

). Periodic air quality testing to assure compliance

is mandatory.

Filter Element Life Factors

Breathing air filter element life is typically rated by manufacturer based on an air temperature of 80ºF
at the filter inlet. Under normal operation this temperature is 12ºF (5ºC) warmer than the ambient air,
resulting in an equivalent ambient temperature rating at 68ºF (20ºC).

To determine element life at a different ambient temperature, multiply the rated life by the life factor
listed below:
