  • Page 10: General Information

    Production rates of the blast cabinets are dependent on size of nozzle, compressor capacity, working pressure, type and size of abrasive media and distance between the nozzle and the cleaning surface. Contracor suction type blast cabinets consist three modules: 1. Ruggedly built welded steel cabinet enclosure. 3.2. Theory of operation.
  • Page 11 3.4. Blast media. manufactured for dry blasting. Steel blast media: Still grit or shot can be limited used with CAB-110S and CAB-135S cabinets (max. mesh size ca. 0,80 mm). Rubber curtains should be used to protect the cabinet walls from rapid wear.

    ATTENTION! Abrasive blasting with sands containing crystalline silica can cause seri- ous or fatal respiratory disease. Slags are not recommended because they rapidly breakdown. Aluminum Oxide, Silicon Carbide, and Garnet: Aggressive media such as these may be used but consideration should be given to accelerated wear on any part of the cabinet, reclaimer, nozzle and hoses which comes in contact with the media.
  • Page 13 ATTENTION! blast cabinet. Hose disconnection while under pressure could cause seri- ous injury. 4.1.3 Grounding Ground the cabinet to prevent static electricity build up. For grounding attach an external grounded wire to the grounding lug on the cabinet skirt. 4.1.4 Electrical power connection ATTENTION! to the national and local standards.

  • Page 15 4.2.4. Blasting operation ATTENTION! Always close cabinet, reclaimer and dust collector doors before blasting. Keep all doors closed during blasting. Always wear blast gloves. Avoid pointing the blast nozzle toward the view window. Use the blow-off nozzle to blow media off parts before opening doors. After blasting, keep doors closed and exhauster on until the cabinet is clear of all airborne dust.
  • Page 16 During the blast cabinet operation, dust collector is pulsed automatically according to the timer settings. Prolonged periods of blasting or duty conditions may require adjustment of the timer settings. 4.2.5. Stop blasting operation and shut-down. To stop blasting, remove pressure on the foot pedal. Use the air blow-off nozzle, to blow media off cleaned parts.
  • Page 17 Adjusting Screw holes fully open holes fully closed Picture 4.3.3. Metering valve adjustment smoothly, the metering valve requires adjusting. To adjust loosen the locking nut, and adjust the metering screw until the hole in the metering stem is half-closed. If pulsation occurs in the media hose, either media is damp and caked, or not enough air is entering the media stream.
  • Page 18 4.3.5 Cabinet static pressure Once the inlet is initially set per section 4.1.5, it seldom requires readjustment. The initial setting produces approximately 50% to 75% of static pressure in the cabinet enclosure. For adjustment open the inlet damper further to decrease static pressure or close it further to increase pressure.
  • Page 19 The interlocks should stop the blasting when the doors are opened, and permit blasting when the doors are closed. NOTE: should be performed with the exhauster on. 4.3.7 Pulse pressure Adjust pulse pressure using the regulator mounted on the pulse manifold. Begin pulse pressure setting at 4,5 bar.

    5. Maintenance 5.1. Preventive maintenance. 5.1.1 GX manual blast gun Inspect the GX manual blast gun for wear. Replacing the air jet cover before it wears through will prolong the life of the jet. 5.1.2 Dust container Empty the dust container regularly. Start by checking the container at least daily or when adding media, then adjust frequency based on usage, contamination and friability of the media.
  • Page 21 (1). Inspect the condition of the rubber shield (3). To change the shield, unscrew the bolts (12)(13), and remove the shield (3), the strip (4), the tightening piece (7) and the pipe bend (5). Reassemble the reclaimer in the reverse order, replacing the gaskets (8)(6) if required.

  • Page 23 Remove the old window by pulling the window molding. Install the window molding in the The molding ends should meet in the middle of the straight section of the opening. Molding should be compressed so the ends are tightly sealed. Working from the front, install the view window into the wide slit of the molding.
  • Page 24 5.2.6 Filter cartridge replacement ATTENTION! Failure to wear approved respirators and eye protection when servicing dust- laden areas of the cabinet and dust collector, and when emptying the dust collector could result in serious eye irritation and lung disease or death. Toxicity and health risk vary with type of media and dust generated by blasting.

  • Page 25: Troubleshooting

    5.2.7 Filter cartridge seasoning New cartridges must be seasoned. Cartridges are seasoned by letting a dust cake develop off (to 0 bar). Operate the cabinet without pulsing for about two hours, or until visibility decreases, 6. Troubleshooting ATTENTION! To avoid serious injury, observe the following when troubleshooting. .
  • Page 26 6.1.7 Reclaimer door open. Reclaimer door have to be closed during the cabinet operating. 6.1.8 6.2 Abnormally high media consumption 6.2.1 reclaimer at this point will cause media to be carried into the dust collector. DO NOT operate system unless the door is closed. 6.2.2 Hole worn in reclaimer, or leak in reclaimer seams.
  • Page 27 6.4.2 Media mixture too rich. Adjust media/air mixture per Section 4.3.3. 6.5. Media bridging 6.5.1 Frequent bridging or blockage in the metering valve can be caused by damp media. Media becomes damp by blasting parts that are slightly oily, from moisture in the compressed air line, or from absorption.
  • Page 28 6.8 Blockage in media hose 6.8.1 Media obstructions. Usually caused when the media mixture is too rich. Adjust media/air mixture per. Section 4.3.3. 6.8.2 Wet or damp media. See Section 3.5. 6.9 Media surge 6.9.1 6.10 Poor suction in media hose 6.10.1 Inadequate air supply.
