Appendix G - Oil Indicator
G.3 Operation
When the needle valve of the oil indicator is
open, filtered medical air will flow through the
calibrated plastic tube. Any oil present in the
air will then carry a red oil soluble dye up the
tube, coloring a white material in the tube. The
rate of color travel will be proportional to the
amount of oil present. The parts per million
(ppm) value of oil entrained in the air can be
determined using the conversion chart below
(FIG G.2). After use the needle valve should
be closed and left in line and the cartridge
removed. At the time of the next test, a
replacement cartridge will need to be installed
on the needle valve fitting.
G.4 Reading and Measurements
1. Before taking a measurement, fill out the
record tag furnished with the oil indicator.
Record the line pressure.
2. Fully rotate the needle valve handle coun-
terclockwise to open and record the time
start time. Slide the record tag over the oil
indicator to avoid misplacing it.
3. When checking for oil entrainment, visually
inspect the oil indicator after 40 hours and
measure only to the top of the dark red col-
umn, not light pink area if present. If dark
red column is not visible, discontinue test,
there is no measurable amount of oil pres-
ent in the air stream.
4. If dark red column is visible, record the
actual time and unit mark on the indicator
and close the needle valve.

WARNING!
Do not disturb the factory adjusted
torque on the retaining nut that holds the
indicator plastic tube in place. Tampering
with the nut can cause serious personal
injury or property damage.
G.5 Oil Concentration
Determination
1. To find the Rate of Color travel, divide the
units traveled by the total number of hours.
2. Using the chart in FIG G.2, find the Rate of
Color travel on the left side of the chart and
the pressure on the bottom. The point where
Rate and Pressure intersect is the parts per
million of oil concentration.
G.6 Oil Indicator Replacement
Cartridge
NOTE:
The oil indicator tube must be replaced
with a new cartridge after each test.
1. Before removing cartridge close the needle
valve and leave the valve in place.
2. Remove the old cartridge by unscrewing the
fitting holding the indicator tube. The new
cartridge comes with a new fitting with the
tube installed.
3. Install the new cartridge on the needle valve
and only open the valve when a new test
begins.
