Introduction
Multi-Air Testers are designed to provide a quick and easy method for carrying out accurate periodic
testing of breathing air, medical-air and medical gas supplies. The instrument can test against a range
of standards, for breathing air the European Standard is EN12021, which should be referred to in
conjunction with any overriding national standards. For medical air, surgical air and medical gas the
F4504 is programmed to test against the requirements of European Pharmacopoeia and in the UK,
HTM 02-01.
The F4504, is designed primarily for use on airline systems up to 10bar when used in conjunction with
the F3005 regulator can also test systems up to 20 bar. For testing high pressure cylinders or charging
systems the F3002 High Pressure Regulator is available which has a 200/300 bar 5/8” DIN thread.
Additionally the F4504 will test the following medical gases - CO2, N2and N2O
For some of the medical tests the F4504 uses alternative test methods to those described in the
narrative of the standard.
Standards which the F4504 can test against are:
Breathing Air:
EN12021:2014
Medical:
HTM02-01 Medical and Surgical Air
HTM02-01 Dental Air
European Phamacopeia Medical and Surgical Air
European Phamacopeia CO2
European Phamacopeia N2
European Phamacopeia N2O
The F4504 has a colour touch screen display and is supplied in a hard weatherproof case with storage
provision for a wide range of accessories and equipment. It is primarily designed to be used from
within the case; however the tester can also be removed and operated separately where space is at a
premium.
As well as test ports for chemical reagent tubes/Impactors the F4504 incorporates an electronic
dewpoint meter, electrochemical oxygen cell, digital flowmeter and pressure transducer.
Depending on the standard selected tests are carried out using the Draeger Impactor for oil and
chemical reagent tubes for carbon monoxide, carbon dioxide, sulphur dioxide, nitrous fumes,
hydrogen sulphide and polytest. These are supplied in packs of 10 per type and the chemical reagent
tubes show the degree of contaminant present as a colour change to the crystals that they contain.
The extent of this is read against the scale on the tube. For the Impactor the degree of oil
contamination is displayed on a screen.
Results from the F4504 can be downloaded to PC software which can be downloaded from Factair’s
website (www.factair.co.uk/downloads). The software allows you a convenient way to easily store,
retrieve and print previous test results.

1. Pre-Use
F4504 Multi-Air Testers are fitted with internal lithium rechargeable batteries and in addition also
have a battery tray which accommodates 6 off size AA alkaline type batteries packed separately and
stored underneath the tester within the case. In the event that the rechargeable batteries are not
sufficiently recharged then you can continue to use the instrument with either the Alkaline AA
batteries or mains power supply,
To install the alkaline AA batteries lift the tester out of its case, open the battery drawer at the rear of
the unit and place the batteries inside.
Note: - It is important to strictly observe polarity when fitting batteries and ensure that they are
correctly located.
During use the battery condition is displayed on the screen.
If the Tester is to be used adjacent to a power socket, the mains adaptor may be used. Please note
the unit should be switched off prior to connection or disconnection of the mains supply.
When connected to a mains power supply the internal lithium batteries will be recharged.

7
2. Start Up
To carry out a test first switch on the machine by pressing and holding the green “on” button, located
on the right-hand side of the unit, for approximately 3 seconds.
A splash screen will be displayed which shows the
instruments hardware and firmware versions.
Periodically the firmware is upgraded as part of
the recalibration process as improvements are
identified.
A Stylus pen is provided for use with the touch
screen. The display will show the, date last
calibrated, serial number and a tick or cross
symbol will indicate whether it is within the
recommended calibration period.
The F4504 series has 2 battery level displays, the
left hand one is for the alkaline AA batteries, if
fitted. The right hand one is the rechargeable
internal lithium battery. Unless the instrument is
connected to a mains power supply the
instrument will use the highest of the 2 battery
power sources. Please note if alkaline AAs are
inserted whilst the unit is on their battery level
will not be displayed until the unit is turned off
and back on again.
Press the arrow key to progress to the main
menu.
The main menu has 3 options available from left
to right these are:
Begin test, Review Previous Tests and Set-Up
Menu.
Each of these sub-menus are described in further
detail below
The instrument can also be turned off from this
menu by pressing the red power symbol in the

8
top right hand corner.
Note –If the begin test icon is in grey this will be
because the instrument’s memory is full (20 tests
maximum) and you need to remove at least 1 test
before you can proceed. See Section 4 –
Reviewing Test Results for further details.
3. Selecting the test standard and configuring the instrument
From the main menu press the configure icon.
In the configuration sub menu there are 3 icons
available, from left to right these are:
Set Date
Set Time (the instrument uses a 24 hour clock)
Set units of measure and test standard
To set the date, press the calendar button on the
display as seen above.
In this menu you can then choose date format;
DD/MM/YYYY or MM/DD/YYYY

The times are set prior to the unit being supplied
but they can be adjusted as necessary.
To select the test standard or the units of
measure press the right hand icon.
In this menu you can then choose the following;
CO2sample rate, pressure and temperature units
of measure and the breathing-air test standard.
Once you have made your selection press the
arrow in the top right corner to exit. To then exit
from the configuration sub menu to the main
menu press the arrow at the top left of the
screen.
4. Breathing-Air Tests- All
Having selected the breathing-air standard
EN12021 in the configuration screen, to carry out
a test press the “begin test” icon on the main
menu
The unit will automatically calibrate the oxygen
cell against the surrounding atmosphere; the unit
therefore needs to be in a well ventilated area.
Note:- If the temperature is greater than 40°C
inside the instrument the calibration will operate
for an extended period to stabilise the Oxygen
cell.

10
You now have the option of entering a
description for the test location, if you wish to
use numbers press the “function” button. Push
the right arrow button when you are ready to
proceed.
Choose between using a Draeger chemical
reagent tube or Draeger oil Impactor in the test
port.
For further details on alternative chemical
reagent tubes see appendices 2 and 3.
For breathing-air tests the standard option is to
select a Draeger oil Impactor.
The unit has 4 breathing-air test programmes
available: Airline Systems up to 40 bar (top left);
High Pressure Charging Compressors (top right)
High Pressure Systems up to and including 200bar
and High Pressure Cylinders above 200bar. All of
the high-pressure tests require the use of the
F3002 regulator which has a DIN connector that
can accept input pressures up to 300bar.

11
4.1 Completing an Airline Test
Select (Airline < 40 bar) –note the maximum
pressure the instrument is rated to is 10 bar.
With the flow control valve in the closed position
connect to the air supply to be tested. Ideally this
should be done by using the hose which normally
supplies the breathing apparatus. Fit the
appropriate adaptor to the Tester first and then
connect the supply hose to the adaptor.
A test can be carried out at any pressure between
2 and 10 bar.
Note:- If the unit is over-pressurised it will
automatically shut down and display an
overpressure warning; it will then need to be
returned to the manufacturer for checking and
resetting.
Input pressure will be displayed on the measured
pressure bar graph and the adjacent display.
System pressure will automatically default to this
reading.
Note:- The pressure dewpoint at the end of the test will be calculated on the recorded system
pressure.
For the majority of applications the system pressure can be left at this default setting, however if the
breathing-air system is distributed as breathing air at a different pressure to that being displayed this
should be entered at this stage.
To enter press the right hand side (Set) icon use the keypad to enter the required value, press the
right arrow to return. The (Reset) button will automatically reset the system pressure back to the
measured pressure.
Press the arrow key to proceed.

12
We can now confirm the flow and pressure is
adequate for your respiratory protective device.
Adjust the system’s flow control valve so that the
flow meter registers the required level*, check
the pressure is sufficient for the breathing-air
equipment being used. It is recommended that
this flow is left running for the duration of the
test to simulate the conditions of use. Press the
arrow key to proceed if the flow and pressure
meet the minimum requirements for your RPD.
*Note:- At high flow rates hearing protection should be considered.
Carry out the odour test and smell the air
exhausted from the sintered outlet. If there is a
serious odour problem, fail the sample at this
point of the test by pressing the ‘fail’ button.
Initiating flows of seriously contaminated air
could result in damage to the instrument. If the
odour test is satisfactory, press the ‘pass’ button.
The instrument will now commence a 5-minute
purge sequence, during which time an airflow will
be passed through the test port and across the
electronic cells. This clears contaminants from
previous tests and ensures that a representative
sample is being tested.
Once the purge has finished, the CO, CO2and
Draeger Impactor/oil tube should be inserted into
the corresponding 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 button in top right hand corner
to start the test.

13
The test will now commence and the duration will
be displayed as a countdown, together with
pressure, flowrate, ambient temperature, carbon
dioxide, carbon monoxide and oxygen content.
During the test the flowmeter should be set to
simulate the requirements of the respiratory
protective device RPD.
The unit can be left until the test time has
elapsed.
If the instrument detects that the dewpoint
meter’s rate of change is still too high (>0.2 dec C
per minute) it will automatically continue the test
until this stabilises (maximum test time 15
minutes).
Once the test is complete close the flow control
valve, the readings from the Impactor can now be
entered.
To enter the results press the corresponding icon
on the screen.
Note:- Instructions on reading the Impactor can
be found in Appendix 3 at the back of the manual.
The tube readings should also then be entered,
push the button corresponding to each chemical
reagent tube / Impactor.

14
Input the reading from the tube / Impactor and
press the arrow icon in the top right hand corner
of the screen.
The “test complete” screen displays all the
measurements recorded during the test. And
automatically determines whether the test was a
pass or fail against the standard displayed in the
top right corner of the screen. The water content
on low pressure tests is displayed as a pressure
dewpoint. The test result is recorded in the
instrument’s memory, which can store up to
20 previous tests.
If the test was a fail an orange exclamation mark
would be indicating those criteria which did not
meet the standard. The photograph opposite is
an example of a failed test where carbon dioxide
failed to meet the requirements of the selected
standard.
For airline systems less than 40 bar the pressure dewpoint, i.e. the point at which water will begin to
condense into a liquid form in the airline, must be at least 5 degrees centigrade below the lowest
temperature at which the system will be used. The F4504 automatically calculates the pressure
dewpoint from the measured water content and system pressure, it then compares this to the
ambient temperature to determine whether it was a pass or fail.
This test result is automatically recorded in the instrument’s memory, which can store up to
20 previous tests. To view these tests return to the main menu and press the “Review Tests” button.
Test results are stored accordingly to the date and time they were completed. From this menu
previous tests can be viewed or deleted as required.

15
To disconnect the Tester from the system make sure you leave the inlet adaptor on the instrument
and only disconnect at the end of the supply hose. The adaptor can then be disconnected afterwards
if required.
To turn off the Tester use the return arrows to return to the main menu screen and press the X in the
top right hand corner of the screen.
Note: - The unit will automatically turn off after a few minutes if left unused at the main menu screen.
4.2 Completing a High Pressure Test
For high pressure tests there are 3 different test options available. All of the high-pressure tests
require the use of the F3002 regulator which has a DIN connector which can accept input pressures of
up to 300 bar.
High-pressure charging compressors
High-pressure cylinder less than 200bar
High-pressure cylinder greater than 200bar
Note: For cylinder tests please ensure the test is carried out on a recently filled, fully charged cylinder.
Note: For the high-pressure charging compressor test a DIN to DIN adaptor ref: F2158 is required to
connect the F3002 high-pressure regulator to a charging hose.
To carry out a test press the appropriate button.
Ensure that the flow control valve is fully closed
and then connect the F3002 high-pressure
regulator assembly to the cylinder or charging
hose to be tested, ensuring that the regulator has
the correct type of connector for the cylinder.
Connect the regulator hose coupling to both the
regulator and the inlet of the Tester.
Open the cylinder valve and check that the cylinder is fully charged by reading the contents gauge on
the regulator. (A partially discharged cylinder can give an incorrect water result.) The pressure
displayed on the tester will be that of the regulated supply from the cylinder and must not exceed
10 bar. Press the button in the top right hand corner to proceed.
Note:- if the unit is over-pressurised it will automatically shut down and display an overpressure
warning; it will then need to be returned to the manufacturer for checking and resetting.

16
Carry out the odour test by gently opening the
flow control valve and smelling the air exhausted
from the sintered outlet, then close the valve. If
there is a serious odour problem, fail the sample
at this point of the test. Initiating flows of
seriously contaminated air through the tube ports
could result in damage to the unit. If the odour
test is satisfactory, press the ‘pass’ icon.
The instrument will now commence a 5-minute
purge sequence, during which time an airflow will
be passed through the test port and across the
electronic cells. This clears contaminants from
previous tests and ensures that a representative
sample is being tested.
Once the purge has finished, the Draeger
tube/Impactor should be inserted into the
corresponding 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 button in top right hand corner
to start the test.
The test will now commence and the duration will
be displayed as a countdown, together with
pressure, ambient temperature, carbon dioxide,
carbon monoxide and oxygen content.
The unit can be left until the test time has
elapsed.

17
If the instrument detects that the dewpoint
meter’s rate of change is still too high (>0.2 dec C
per minute) it will automatically continue the test
until this stabilises (maximum test time 15
minutes).
The Impactor can now be 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 3 at the back of the manual.
The “test complete” screen displays all the
measurements recorded during the test. And
automatically determines whether the test was a
pass or fail against the standard displayed in the
top right corner of the screen. For water content
on high pressure tests both the measured value
in mg/m3and the atmospheric dewpoint are
provided.
If the test was a fail an orange exclamation mark
would be indicating those criteria which did not
meet the standard. The photograph opposite is
an example of a failed test where carbon dioxide
failed to meet the requirements of the selected
standard.
