Introduction
The F8104 Safe Air Monitor is designed to provide continuous monitoring of breathing-air and
compressed-air systems. Once set up the instrument will continue to monitor and data log the air
quality at user defined intervals, validating the air quality against a range of alternative international
standards. For medical, surgical, dental air and medical gas the F8104 is programmed to test against
the requirements of European Pharmacopoeia and in the UK, HTM 02-01.
The F8104, is designed primarily for use on airline systems up to 10 bar but can also test higher
pressure systems up to 20 bar when used in conjunction with the F3005 High Pressure Regulator.
High pressure cylinder air can also be tested with the F3002 HP regulator.
The F8104 is supplied in a plastic protective case with storage provision for accessories.
The test is carried out using built in electrochemical cells for carbon monoxide and oxygen; infrared
LED sensor for the carbon dioxide and a Photo Ionisation Detector (PID) for Volatile Organic
Compounds. The moisture is measured with an electronic dewpoint meter and the instrument also
records pressure and ambient temperature. For measuring oil aerosols, Dräger Impactors are used in
the side mounted test port (or alternatively the Dräger oil chemical reagent tube). The Dräger
Impactors are supplied in packs of 10 and show the degree of oil contamination on the cut glass baffle
plate.

1. Pre-Use
The F8104 is supplied with a mounting plate which enables the instrument to be wall mounted at the
most suitable location to test your breathing-air / compressed-air supply. The test location needs to
be as close to the breathing-air supply point as possible, in a well ventilated area free from dust and
with a 230V mains power supply available. To install the back plate mark the hole locations on the
wall and check with a spirit level. Ensure you use the correct fixings to suit the wall.
Once you have installed the back plate mount the F8104 in place and connect the power supply. It is
important the unit is free from vibration during use. The F8104 Safe-Air Monitor requires a
230V/1ph/50Hz mains power supply.
The maximum compressed air supply pressure for the F8104 Safe-Air Monitor is 10 barg. If the
instrument is intended for use on a high pressure system contact Factair for advice on suitable
regulators and connection arrangements.
2. Start-Up
To turn the instrument on press and hold the “on” button, located on the right-hand side of the unit,
for approximately 3 seconds.
A stylus pen is provided for use with the touch
screen. The display will show the calibration
date, serial number and check the status of
each sensor. Once each sensor status has been
checked follow the touch screen prompt on
screen to proceed.
The compressed-air supply can then be
connected to the instrument
(minimum 2 barg, maximum 10 barg).

3. Continuous Monitoring Display
By tapping the calibration date screen, the
instrument will then display the home screen.
In the top right hand corner a countdown will
commence for a commissioning delay during
which time the sensor readings are stabilising
and the alarms will be disabled.
The duration of the commissioning delay can
be later adjusted in the installer menu.
If the sensor readings have already stabilised
you can commence immediate sensor
monitoring by pressing the “Commissioning
Delay” countdown icon.
Once commissioning is complete the home
screen will display all live sensor readings.
Individual sensor readings can be further
interrogated by pressing on their readings bar.
The number and order of the displayed
sensors can be changed in the installer menu.

3.1 Completing an oil test using a Dräger Impactor or tube
The instrument displays the date and result from
the last oil Impactor or tube test.
To undertake a new test tap the result button.
Choose between using a Dräger oil Impactor or
Dräger chemical reagent tube in the test port.
For breathing-air tests the most commonly used
option is to select a Dräger oil Impactor.
Instructions for using the Dräger tube can be
found in appendix 1.
The instrument will now commence a 5-minute
purge sequence, during which time an airflow
will be passed through the test port. This clears
contaminants from previous tests and ensures
that a representative sample is being tested.
Once the purge has finished, the Dräger
Impactor/oil tube should be inserted into the
test port and tightened firmly; ensure the
Impactor has an intact protective seal. This seal
must remain in place for the duration of the
test. Press the arrow on the right hand side to
start the test.
At the end of the test the Impactor result screen
will be shown. The Impactor should now be
taken out of the test port, sticker removed and
evaluated.
To enter the results press the corresponding icon
on the screen.
Note:- Instructions on reading the Impactor can
be found in Appendix 2 at the back of the
manual.
The test result and date of test will then be
displayed on the home screen.

audible tone will be emitted in the event of
any of the readings exceeding their minimum
and maximum value.
This is an optional, factory fitted feature
which allows a beacon to be fitted on the unit
itself.
If Power Fail is selected, then in the event of a
failure of the mains power supply, it will
activate the alarm.
To function correctly the F8104 requires a
minimum 2 barg supply pressure (10 barg
maximum). In the event the supply pressure
falls below 2 barg, the unit will activate its
alarm. For situations where the drop in
pressure may only be temporary a delay can
be added (in seconds) before the alarm is
activated.

To prepare the tube Factair recommends the F2187 Dräger tube tip cutter.
If you have another Dräger tube, which you wish to use with the instrument, contact Factair for
technical advice on its suitability.
To complete a tube test, select a tube test
option as shown, press the button to proceed.
If you can determine with a high degree of
certainty the specific compressor lubricant
being used, then refer to the “test times” chart
provided on Factair’s website marked for the
F8104. If you have no knowledge of the type of
compressor lubricant being used in the
breathing-air system then Factair recommends
15 minutes as this covers the vast majority of
lubricants.
Once the instrument has completed its purge
sequence you will be prompted to insert the
tube into the test port and tighten firmly.
Note: Both ends of the tube should only be cut
immediately prior to the test. Ensure the arrow
printed on the tube is pointing away from the
instrument.
Press the right hand arrow to proceed.

18
The test will proceed as described in section 4
and at the end of it you will be prompted to
enter the result from the tube.
The result will then be displayed on the final
test result screen and stored in the instrument’s
datalog file.

19
Appendix 2 - Reading the Dräger Oil Impactor and Oil Chemical Reagent Tube
Oil Impactor
The Oil Impactor’s protective seal must be kept in place for the duration of the test and only
removed after the test has been completed.
With a standard measurement range of 0.1 to 1.0 mg/m3the Impactor has a limit of detection of
0.05 mg/m3. The Impactor can detect all mineral and synthetic oil mists, it features a series of 3
horizontal lines, each formed by a series of precision manufactured nozzles. These horizontal lines of
nozzles are calibrated to a different concentration of oil. When air is passed through these nozzles
any oil present in the air is deposited on the glass plate prior to the air being exhausted by vents
around its circumference, this allows the user to easily and quickly identify minute quantities of oil.
For tests that pass with an oil concentration of less than 0.05mg/m3, the screen will remain blank. For
tests above that read as follows:
The bottom line represents an oil concentration of 0.1 mg/m3. When the oil deposited forms a
continuous line then the concentration is in excess of 0.1 mg/m3. The middle line represents a
concentration of 0.5 mg/m3, again when the oil deposited forms a continuous line the concentration
is in excess of 0.5 mg/m3. The top line represents a concentration of 1.0 mg/m3, again when this
forms a continuous line the concentration is in excess of 1.0 mg/m3.
