G.2 Function
The Oil Indicator is a calibrated measuring
instrument used to detect aerosol mist levels
of oil entrainment that may be present in the
medical air system. Sensitivity of the indicator
is limited only by the total number of hours it
is allowed to remain on the air supply system.
The indicator is sensitive enough to measure a
concentration of oil entrainment as low as .01
ppm (.012 mg/m3) in a compressed air system.
It can be used in systems with line pressures
between 10 and 125 psig (70 and 875 kPa). Inline
pressure regulator for oil indicator factory set at
50 psig. NFPA requires a 0.05 ppm ± 0.03 ppm
reading or better in the air stream.
Appendix G - Oil Indicator
WARNING!
If the pressure exceeds 125 psig or the
retaining nut is loosened, the oil indicator
tube could blow out of the compression
fitting, creating a hazardous condition.
