KWIK DRAW UNIPHOS
Airtester HP (Multiport Sampling)
for compressed air according to EN 12021
Instruction for use
1. Use
The compressed air monitoring set “KWIK DRAW
UNIPHOS Airtester HP” (HP = high pressure) is used
to determine the content of carbon monoxide, carbon
dioxide, oil and water vapour in respirable air from
compressors and compressed gas cylinders. .
According to EN Standard 12021 air for respiratory
equipment must meet the following quality
requirements:
CO content max. 15 ppm
CO content max. 500 ppm
2
Free of odor and taste, i.e. practically free of
critical mineral oil content (from experience the oil
content is less than 0.5 mg/m³)
Water content in compressed air cylinders:
max. 50 mg/m³ at a charging pressure of 200 bar
max. 35 mg/m³ at a charging pressure of 300 bar
max. 25 mg/m³ of the air from the compressor
-
-
-
-
The requirements concerning the maximum water
vapour content refer to the type of equipment used
(200 or 300 bar) and, therefore, apply also to each
pressure level of the compressed gas cylinders
below the maximum values given above. .
All maximum values are based on air not under
pressure.

6. Maintenance
6.1 General
In view of the significance of the accuracy of
measuring results, the test device must be treated
with care. Dirt must be avoided at all time, especially
at the high-pressure connection.
Flushing and cleaning of the test device must be
made as described in para. 5.2. After measuring is
completed, the test device shell is stored in the case.
The high pressure connection should be closed with
a protective cap.
Function checks should be made at regular intervals
and if erroneous measurements are suspected.
6.2 Disorders
If the hand wheel of the test device cannot be
loosened while it is connected to a compressed gas
cylinder or compressor, check if connection is under
pressure. In this case close the cylinder valve or
compressor valve and release air from test device.
Leaks at the connection to the cylinder or
compressor could be due to a defect gasket. In this
case replace the gasket.
If the high pressure gauge or the detector tube holder
is defective, they must be replaced.
In case of other disorders the device should be
returned for repair to UNIPHOS or any authorized
service station.

The pressure in the compressed gas cylinders, or
in the compressor charging panel is reduced by a
pressure reducer. The air to be sampled is taken
continuously via a regulatory valve in the manifold.
There are four outlets for this manifold which release
fixed flow rate of gas. The flow rate of each port is
printed on the body of the manifold, viz 0.3 l/min,
0.3 l/min 1.0 l/min and 2.5 l/min. The air coming out
from these ports is taken through detector tube for a
specific time. The length of stain in the detector tube
is an index of the concentration of the measured
substance. This can be read directly from the detector
tube scale.
The test device, consisting of pressure reducer,
Pressure gauge, manifold, flow meter, detector
tube holder, adapter for connection to a
compressor charging panel ( for charging
connection 300 or 200 bar), timer, detector tube
tip breaker, tubes (package of 10) for measuring
CO, CO2, water vapor and oil content (sum of
Oil vapor and mist). .

All values above are based on air not under pressure
and at room temperature and normal pressure.
5. Operating Instruction
5.1 Preaparing for Measuring
5.2 Measuring on Compressed Air Cylinders
When the test device is clean and dry flushing for
2 min. is sufficient. If the condition of device is not
known, or if during a previous measurement higher
values were found than are permissible according to
EN 12021, flushing at 2 l/min. must be continued.
This must b e done until 2 w ater vapor
measurements, made at an interval of approx. 15
min., give identical results within the permissible
measuring accuracy range. It then can be assumed
that the test device is sufficiently clean for making
measurements. .
Liquid/ water (droplets) can only be removed from
the test device through long flushing with dry, if
necessary warm air. .
.
Observe arrow on the detector tube. The arrow
points in the flow direction of the test air; therefor,
after inserting the tube, the arrow must point away
from the test device. .
Clean valve of compressed gas cylinders or
charging connections of compressor with brief
burst of air. .
Chose and connect the adapter suitable for the
prescript maximum pressure of the compressor
charging panel (300 or. 200 bars). .
Connect pressure reducer to compressed gas
cylinder, or to charging connection of compressor
using the adapter. .
Insert and firmly fit the nozzle of manifold on the
pressure reducer as shown in fig. 2 .

Break off the detector tube tips at air exit side
(see fig. 5) .
Put detector tube into the tube holder, inserting
broken-off end tightly into holder side away from
test device. .
Break off other end of the detector tube (air entry
side) and immediately insert open tube tightly into
other end of detector tube holder (close to test
device). (see fig. 6). .
Immediately thereafter start the timer to the time
designated for the type of detector tube.
Remove the detector tube of CO, CO2 and H2O
after 5 minutes from the tube holder and take the
readings from the printed scale on the tube.
Remove the oil detector tube from the tube holder of
test device after 24 minutes and take the readings
from the printed scale on the tube.
5.3 Measuring on compressors
Switch on the compressor
Wait until 200 or 300 bar are reached
Switch off the compressor
Slowly open valve on compressor
Flush test device as scripted in para. 5.2
The water content that is measured in air from a
compressor only corresponds to the water content of
compressor gas cylinders simultaneously charged, or
cylinders charged immediately after measuring, if a
pressure retaining valve is built into the compressor at
the exit side of the drying cartridges. A prerequisite,
however, is that the cylinders to be charged are dry.
The pressure retaining valve assures that the pressure
inside the compressor drops only insignificantly from
the maximum pressure of 300 or 200 bar, when
cylinders are being charged. With compressor that has
no pressure retaining valve behind the filters, water
from the drying cartridge can be released to the
sudden decompression when the charging connection
is opened. The air has then higher water content as
was measured on the compressor charging panel. .
MSA AUER compressors normally have a pressure
retaining valve.
