1. Introduction
The AIRBLAST's Vacuum Blasting technology is a new concept for cleaning many types of
surfaces quickly, thoroughly and without environmental pollution.
The AIRBLAST 1070 PNE machine is designed as a high capacity direct pressure-blasting
machine featuring a continuous blast media feed system. This feature allows the machine to
be kept compact and lightweight but with a minimum down time for media loading and
machine handling.
During the blast operations, the dust and debris are separated from the re-usable abrasive
for simple disposal. Only the cleaned blast media recycles to provide optimal surface prepa-
ration.

* All hose connections with claw couplings should be provided with safety clips.
* Do not use worn brushes as these will allow blast media and dust to escape into the
atmosphere. Check the brushes for service ability.
* Place the blast gun brush flat against the surface to be treated before pulling the trigger.
Release the trigger and wait a few seconds for abrasive flow to stop before lifting the blast
gun from the surface.
* Do not attempt to use this equipment without proper lighting and visibility.
* When opening and cleaning the dust compartment, or otherwise performing any work on
the equipment where dust is generated, always wear eye protection and a proper
respirator. Technicians should do this only.

6. Transport
The bottom of the machine frame is provided with two tubular sleeves for the forks of a Fork
lift truck. In this way the machine can be transported safely. Another possibility is to move
the machine by crane or hoist. For this reason two lifting lugs are incorporated in the frame
machine.
In case of transport always make sure that dust valve is completely closed.

USER MANUAL VACUUM BLASTING MACHINE 1070 PNE AIRBLAST

7. Machine function
During the blasting operation the abrasive is propelled at a high speed through the blast
head against the surface to be cleaned. After cleaning the surface, the abrasive - together
with the rust or coating removed from the surface - is vacuumed back into the machine
through the suction hose.
In the dust separator, the exhaust speed of the abrasive and dust is reduced by means of
collision pads. Below the last collision pad is a fine wire mesh screen through which the dust
and small spent abrasive will pass. Since these pads are placed at an angle, gravity causes
the re-usable abrasive to fall back into the hopper above pressure vessel. Any larger waste
particles will be caught by the sieve.
Below the last collision pad with fine mesh there is an exhaust opening leading to the filter
section. The dust is drawn back to the filter chamber where the heavier dust falls directly into
the bottom of the dust chamber and the remainder is drawn to the filters. The fine dust clings
to the filters and the clean air is blown back into the atmosphere through the vacuum
generator. To prevent the filters becoming clogged, they can be cleaned by pushing the knob
on the dashboard indicating “filter cleaning” a few times each four hours (Filter back-flush
system). Depending upon the abrasives being used and the surface being blasted the filters
must be cleaned less or more frequent.
The single-chamber pressure vessel functions as follows: By means of a pneumatic solenoid
and trigger action, the pressure vessel is pressurised. The pressure vessel is always
pressurised as long as the trigger is activated. Now the abrasive, under pressure, passes
through the abrasive control valve into the blast hose. At the end of the blast hose the
abrasive passes a nozzle and gets propelled against the surface inside a blast head.
Whenever the upper chamber is depressurised, the valve on top of it will open and the
abrasive stored above it will flow in to the upper chamber.

8. Setting up for operation
8.1 Installation instruction
Connect the machine to a compressor with a minimum capacity of 10 m3/min (375 CFM) and
a maximum pressure of 9 bar (130 PSI) at the compressor. The pressure vessel of the
machine has not been designed to operate above 116 PSI. To ensure optimal operation of the
machine, you must use dry, clean, oil-free air. It is recommended that a water separator is
installed in the supply air line, as close to the AIRBLAST 1070 PNE as possible. If the
compressor you are using does not have an outlet air after-cooler built in, you also need a
stand-alone after cooler during warm, humid operations.

Be certain that the compressed air supply hose is connected to the coupling on the back of
the machine. Be sure to use safety clips on all hose connections!
* Be sure that the inside diameters of the air hoses are correct and that there are no
obstructions. Avoid using small diameter hose couplings as well as an excessive
number of couplings. The correct minimum hose/coupling diameters are as follows.
Hose Length Inside diameter
To 5 meter (16’) 31.75 mm (1 ¼”)
To 25 meter (82’) 38.1 mm (1 ½”)
To 50 meter (164’) 50.8 mm (2”)
To 250 meter (820’) 63.5 mm (2 ½”)
1. First connect the blast hose with the claw coupling on to the machine.
2. Connect the suction hose of the blast head to the top vacuum connection of the dust
separator .
3. Connect the start/stop control hoses to the connection on front side of the machine.

8.2 Filling the machine
* Remove both hoses from the dust separator and disconnect the three clips. Now, the dust
separator can be removed.
* Fill the machine up by pouring abrasive through the sieve up till the Pop up valve is
covered. (this is a total of approx 25 liters or 100 kgs of metallic abrasive!!) Do not
overfill the pressure vessel because this will lead to a waste of abrasive.
* Then replace the dust separator on the machine, fasten the clips and connect the suction
hoses and. Do not drop paper or other foreign material into the machine. These
particles can cause blockages.

Revision 1 January 2012 page 8.3
8.3 Adjustments
Throughout this manual, you may be asked to "test run" the machine for adjustment and
diagnostic purposes. It is recommended that you have a flat piece of scrap steel nearby the
machine. In this way the operator can run the blast gun within reach of the machine and
make the necessary adjustments.
Remember to wear personal safety equipment.
8.3.1 Setting the pressure
* The first step to calibrating the machine is to adjust the blasting pressure. This is done
by the pressure regulator on the operating panel and is indicated by pressure gauge on
the operating panel.
* Hold the blast head as described in the proceeding paragraph, open the ball valve and
squeeze the trigger. Keep the blast head on the surface. Allow the machine to operate for a
few seconds and note the reading on both the pressure gauges. For efficient machine
operation it is important that the blast pressure is adjusted in such way that no abrasive or
dust is spilled at the blast head.
Additionally, it may be desirable to decrease the pressure when blasting on a soft surface or
such as cement or to increase the pressure when blasting with steel abrasives. In case of a
lower blast pressure, adjustment of the vacuum can be obtained. The vacuum controlled by
air pressure adjustment on the vacuum generator is an option. Ask your dealer/manufacturer
for advice. Adjust the blast pressure by turning the knob on the control panel.
NOTE: never attempt to operate the machine at a blast pressure lower than 1 bar ( 15 PSI).

Revision 1 January 2012 page 8.4
8.3.2 Adjustment of the abrasive control valve
* To establish the correct abrasive flow, you must first close the valve clockwise until you
just feel the valve seat. Do not close the valve too firmly or you may damage the rubber
diaphragm.
* Then open the valve by turning from 3 to 3½ turns counter clockwise.
* Test blast to determine if a smooth blasting sound is obtained together with an optimum
blasting pattern. Adjust as necessary, an eight (1/8) of a turn at a time, to obtain the
desired blasting pattern. The actual adjustment for abrasive flow is dependent on the
abrasive type, size and operating pressure selected. Check the pressure on the gauges.
NOTE . DO NOT TURN THE ABRASIVE CONTROL VALVE DURING OPERATION.

9.1 Inspection procedure before starting up
Before putting the machine into operation, the following has to be checked:
* Check all the coupling connections and check the locking by means of the safety clip.
* Check the pressure gauges for the right values.
* Check the amount of abrasive.
* Check if the dust exhaust valve is closed completely.
* Check if all personal safety equipment is present.
* Check the machine visually for loose components and general safety provisions.
* Check the quality of the hoses and nozzle
* Check the quality of the blast head, the brush and blast tube; ensure that the brushes
seal well.
* Finally check at last the general functioning of the machine.
9.2 Operating instructions
To put the machine into operation the following has to be done:
* Uncoil the hoses as much as possible and prevent unnecessary bends.
* Open the main air valve.
* Check if the inlet pressure gauge indicates a steady pressure of approximately 116 PSI.
If this gauge reading is not obtained, see chapter 8.3.1.
* Place the blast head on the surface to be blasted. Make sure the brush seals off
properly.
