1. Mode of Operation
The Airofog pulse-jet thermal foggers operate on the principle of the one-sided
open jet-tube (resonator) with a valve at the inlet side (carburetor) and an open
outlet (fog outlet). This pulse-jet system (operating without any moving parts) that
consists of a carburetor, mixer tube, combustion chamber and resonator, consti-
tutes an acoustical oscillation system at an optimum frequency.
At the end of the resonator, fogging solution is injected in the air stream emerging
at high velocity, and is dispersed into the finest aerosol droplets and distributed into
a lightly suspended fog.
The temperature at the point where the fogging solution is fed in is in the range of
400-600C with the solution being exposed to the heat for not more than 4 to 5
milliseconds. Therefore heat sensitive substances can also be used.

6. To Prepare the Appliance Ready for Use:
The appliance comes packed in a cardboard box. Check that it is in undamaged condition
after removing it from the box.
It is only for packing purposes that the fog tube is not fitted.
To avoid overheating the appliance, start the appliance ONLY after the fog tube
(108 / 109) is fitted (Fig. 2 & 3) with the resonator.
Pull out the fog tube (108) from the
cooling jacket (100), select appropriate
connection (oil-base or water base)
and push back the fog tube into the
cooling jacket, allowing the tube hole
to line up with the resonator (101)
thread.
(Fig. 2)
After screwing in the fog solution
socket (114) by hand, join the solution
dosage nozzle (117) to solution tube
(116) together with copper gaskets (118)
to the solution
socket (114).
It is necessary to counter hold with the
second spanner at the hexagon of the
solutions socket.
(Fig. 3)
Insert batteries as per diagram. The
positive pole is situated in front of the
gasoline tank (10) and the negative
pole on the battery
cover (71).
(Fig. 4)
For better performance, use
Alkaline batteries.

7. Select Fog Solution Output and Fog Tube:
Solution throughput of the available dosage nozzle (measured with water).
Solution nozzle size Ø throughput L/H, approx.
0.6 5
0.7 8
0.8 12
1.0 18
1.2 23
1.4 36
1.6 42
The outputs vary according to different chemicals and physical propertises
of the formulations. We advice that you do your own metering of the output
under prevailing conditions.
For water based solutions choose nozzles up to Ø1.0 mm.
For better performance, we recommend special fog tube (109) and fog solution
socket (114/1) for water based product.
For oil based solutions we recommend nozzle sizes Ø 0.8 and above.
Then use the standard oil based fog tube (108) ONLY.
Smaller nozzles reduce the droplet spectrum. Larger nozzles may cause
an unsatisfactory droplet spectrum.
Never operate the appliance with the water based fog tube when oil
based fogging mixtures with carriers of inflammable substances are
applied.
!

~13~
~12~
8. Fogging Mixture:
Principally preparations of the chemical industry and biological products, which
can be mixed either with water or with oily carrying mediums, can be fogged.
Carrying mediums for fogging are:
• for preparations miscible with water:
1. pure water
2. special fog carriers, e.g. glycerin, glycols
3. white oils with suitable emulgators
4. a mixture of 1. and 2. or 1. and 3.
• for preparations miscible with oil:
5. diesel oil, heating oil or kerosene
6. white oils and vegetable oils in a viscosity similar to diesel oil
7. special fog carriers
When fogging indoor, it is essential that fire precaution is taken.
All naked lights must be extinguished and electricity turned off.
It is recommended that with oil-based pesticide formulations not
more than 1 liter per 400m3be released in order to avoid any
fire risk. A single spark can set off an explosion when more than
1 liter of a formulation containing kerosene is fogged per 300m3.
Observe applicable laws when selecting active solution and/or
carriers.
We cannot be held responsible for damages to person or to property,
directly or indirectly, due to unsuitable fogging
solutions or incorrect
dosage.

1) Pull stop button (52) outwards.
(Fig. 11)
2) Press starter button (78) and keep
press actuate air pump (91). Pump
regularly and evenly. When the first
explosion is audible, pump another
1~2 strokes.
(Fig. 12)
3) After starting, let the appliance warm up
for about 1 minute.
- open the solution tap (120), the appliance
will fog
- in order to stop fogging, close solution
tap (120).
(Fig. 13)
The lower the gasoline in the tank, the more pumping strokes are
necessary. Therefore, when possible, always start with a full tank.
Make sure that the gasoline volume is sufficient for the intented
period of fogging.
If your appliance is equipped with an emergency cut-off device
(AR9E / AR35E), always check the function of the device in
accordance with para. 15 “Check of function”.

10. The Appliance Stops Unexpectedly
Take the following urgent measures when the appliance stops unexpectedly
due to a lack of fuel or mechanical failure:
- Close the solution tap (120) immediately.
Close the solution tap to avoid the fogging
mixture being conveyed by the over -
pressure in the solution tank and reaching
into the hot resonator without being
fogged.
There combustible fogging mixtures can
ignite, thereby creating the risk of fire at
the carburetor and / or fogging outlet.
(Fig. 14)
- Hold the appliance with the fog mixing
tube pointing downwards.
The appliance has to be held with the
fog mixing tube pointing downwards
to allow the chemical solution residue
to run out. Small quantities of
combustible solution can ignite and
have to be extinguished immediately.
(Fig. 15)
It is not allowed to leave the appliance unattended while operating in any case.

11. Stopping the Appliance:
1) Close solution tap (120) by 1/4 turn to clear
or ventilate the solution pipe (116).
(Fig. 16)
2) Wait until fog is no longer visible. Now close
solution tap (120) completely(lever upwards).
(Fig. 17)
3) Press stop button (52) until no explosions are
audible.
(Fig. 18)
4) Release pressure from solution tank by
unscrewing the solution tank cap (2) by 1 to 2
turns then retighten the cap.
(Fig. 19)
After stop the appliance always release
pressure from solution tank because the
solution tank is still under pressure and
solution can get out when the solution tap
open by mistake.

12. Correct Adjustment of the Appliance:
• Turn regulating needle (17) approx. 1/2
counter clockwise then start the appliance.
(Fig. 20)
• Let the appliance warm up for at least 1
minute.
• Check the flame at the resonator (101)
end by obliquely looking into the resonator
at a safe distance (approx. 2m).
Wear safety glasses for protection.
• For fine adjustment, cautiously screw the
regulating needle (17) clockwise or counter
clockwise until the flame is no longer
visible.
(Fig. 21)
When the adjustment is correct the
running is steadily strong and no flame
appears from the resonator end.
NEVER run the appliance over -
adjustment (high frequency sound,
flame appears from the fog tube)
because this causes power loss and
overheating, and may lead to fire hazard.
Due to big differences in outside conditions such as climate and sea-level, the
appliance must be re-adjusted although every appliance is checked before delivery.
Please fill the fuel tank at least 2/3 full then correct adjustmen in the following steps:
“OVERFLOW”:
It is possible that by too vigorous pumping the carburetor overflows and
gasoline fumes emerge out at the end of the fog tube (108/109). In this
case, close fuel stop button (52), press the starter button (78) and actuate
air pump (91) until no more explosions are audible. Then restart as normal
but do not pump too vigorously.
