ATTENTION!
SAFETY PROCEDURES FOR BLAST CABINET OPERATION.
1. Protective gloves must be worn while carrying out abrasive blasting.
2. Worn out or damaged equipment should never be used during operation.
3. The nozzle should only be pointed at the area to be cleaned. The nozzle
should never be pointed toward the cabinet windows.
4. Only dry and well-sifted abrasive materials, appropriate for abrasive
blasting operations, should be used.
5. Prior to beginning blast cabinet operation it is essential to:
- Make certain that gloves, gaskets, hoses and ttings are not worn out;
- Secure hose couplings with wire, if the couplings are used;
- Make certain that the cabinet is grounded.
6. All doors on the cabinet, reclaimer or dust collector must remain closed
while the blasting procedure is being carried out.
7. Use the blow nozzle to blow media from the blasted parts after blasting,
before opening the doors and before turning off the exhauster.
8. Never open the doors or turn off the exhauster until the cabinet is com-
pletely free of abrasive dust.

3. General Information
3.1. General Information
Contracor abrasive blast cabinets enclose the blasting environment, providing efcient
blast cleaning while keeping the surrounding work area clean.
Blast cabinet production rates depend upon the size of the nozzle, the capacity of the
compressor , the working pressure, the type and size of abrasive media and the distance
between the nozzle and the area to be cleaned.
Contracor ECO-type pressure blast cabinets are made up of three main elements:
1. A robust, welded steel cabinet enclosure,
2. A 13-liter blast machine with a durable FSV-0 metering valve,
3. A dust collector consisting of a highly efcient fan and manually cleaned cartridge lter.
An automatic pulse-cleaned cartridge lter is available as an option.
3.2. Theory of Operation
When the air supply is on, and the cabinet door is closed, the blast machine is ready
for operation by actuating the foot pedal. Only by fully depressing the pedal is the machine
pressurized and blast media are propelled through the nozzle.
After striking the object being blasted, the blast media, along with nes, dust, and by-
products generated by blasting, fall through the mesh work table into the cabinet hopper.
By releasing the foot pedal the machine is depressurized and blasting stops, allowing
blast media to recollect in the machine.
The dust collector lter cartridge is cleaned by opening a ball valve, expanding
compressed air at high velocity against the inner surface of the cartridge.. The expanding
air momentarily reverses airow through the cartridge to release dust accumulated on the
outer surface.
The dust particles fall away from the cartridge and into the hopper for removal.

CONTRACOR®Version 3.1
18
A automatic pulsed air cleaned dust collector is available as an option. Here the
dust collector lter cartridge is automatically cleaned by an electronically timed pulse of
compressed air against the inner surface of the cartridge.
3.3. Blast Machine and Nozzle options
The blast machine pressure vessel is manufactured according to European CE
regulations, as described in attached CE Certicate of conformity. The owner must ensure
and maintain the integrity of the vessel, as may be required in some countries.
After having ensured that the air supply is activated and the cabinet door is closed,
the media chamber can be actuated by the foot pedal. By pressing the foot pedal, the inlet
valve is opened and the outlet valve is closed, resulting in the chamber being pressurized
and the blasting beginning. By releasing the foot pedal, the chamber is depressurized and
blasting stops. The standard nozzle delivered with the blast cabinet is a tungsten-carbide
nozzle with a 5.0 mm orice. In addition, 6.5 and 8.0 mm nozzles are available.
ATTENTION!
Excessive air pressure could cause the media chamber to rupture. To pre-
vent serious injury or death, do not exceed the rated pressure of the media
chamber vessel.
3.4. Blast Media
Contracor cabinets use most common media, 180 mesh and coarser, which have been
specically produced for dry blasting. The appropriate media mesh size and nozzle size are
based on typical media ow. Thick media ow or low static pressure will decrease the size of the
mesh and nozzle that can be used.
Steel blast media: Still grit or shot is acceptable for limited use with ECO-80P…. ECO-
140P cabinets. To protect the cabinet walls from rapid wear rubber curtains should be used.
This special requirement needs to be stated at the time of order.
Sand and Slag: Sand should never be used on account of the respiratory dangers
associated with the use of media containing free silica. Slags are not recommended due to their
rapid breakdown.

CONTRACOR®ECO-series pressure blast cabinets
19
Aluminum Oxide, Silicon Carbide and Garnet: These may be used despite the fact that
they are aggressive media. However, attention must be given to rapid wear on any part of the
cabinet, reclaimer, nozzle and/or hoses which come in contact with the media. A tungsten
carbide nozzle must be used when utilizing any aggressive blast media. A tungsten carbide
nozzle performs 10 to 20 times longer than its ceramic counterpart.
Glass Beads: The majority of beads have been specically treated to guarantee free-ow
operation even under conditions of moderately high humidity. In the case of glass beads having
been subjected to excessive moisture, reuse is possible after thoroughly drying and separating
any lumps.
3.5. Compressed Air Quality
Condensed water from the compressed air is reduced by the air lter at the air inlet
connection. Use of the air lter is of particular importance in areas of high humidity or when ne-
mesh media are being used. Dampness can cause media to clot, restricting free ow through
the feed assembly. An air dryer may be necessary if moisture problems continue.
3.6. Compressed Air Requirements
The required air compressor capacity is determined by the blast nozzle size and pressure.
Table 3.2 Air Consumption
ATTENTION!
Abrasive blasting with sands containing crystalline silica can cause seri-
ous or fatal respiratory disease.

4. Set-up, Operation and Shut Down
4.1. Installation and Set-up
4.1.1 Location
A location should be chosen where compressed air, water and electrical services are
readily available. Access to all doors and service areas must be possible, as well as enough
space for efciently handling large parts.
4.1.2 Compressed Air Supply Line
The compressed air supply line should be connected with min. I.D. = 1/2”” to the cabinet
inlet. Use a exible hose with the same min. I.D. as the main air line when connecting. Blasting
performance may be diminished by using an air supply line or hose with a smaller diameter.
4.1.3 Grounding
The cabinet must be grounded to prevent the build up of static electricity. Attach an
externally grounded wire to the grounding lug at the cabinet skirt.
ATTENTION!
Before using the blast cabinet, make sure that all pipe ttings and hose
clamps are tight. Serious injury could occur if the hose is disconnected
while under pressure.
NOTE: the above table shows only the air required for the blast nozzle. Additional air is
required for the air cartridge cleaning, which must be added to the above values..
The above values are valid for nozzles when new. As nozzle wear increases, so does the
air consumption, up to 70% to 80% more than when new.
