  • Page 2 This equipment is not designed for use in areas designated as hazardous. Contact your local MultiBlast Australia office/representative prior to operating this equipment in a hazardous area.
  • Page 3 How The System Works 2.1 The MultiBlast Australia pressure blast cabinets feature a cabinet to enclose and contain the blasting action , a pneumatically operated , safety interlocked blast pot system , and a dust collection system to ventilate the blast cabinet.
  • Page 4 2.2.3 In this state, even if the foot pedal is operated, the blasting system will not operate as the cabinet door(s) are open, with the door interlock valves in the closed position. 2.2.4 For the blasting system to operate, the cabinet door(s) must be closed, allowing the door striker to contact the door interlock valve plunger, which opens the air circuit.
  • Page 5 2.2.6 With the blast pot pressurised, compressed air is fed to the abrasive valve through the pusher line. As this air passes through the abrasive valve, the abrasive media within the blast pot is gravity fed into the abrasive valve, where is mixes with the compressed air. 2.2.7 The air and abrasive media are then discharged at high velocity through the blast hose, exiting at the blast nozzle attached to the end of the blast hose.
  • Page 6 The ventilation system 2.3.1 The cabinet ventilation system is provided to improve visibility within the blast cabinet for the operator, and also reduce the amount of dust within the abrasive mix. 2.3.2 Depending on the application and cabinet model selected, the ventilation dust collector may be either a drum type unit, or a reverse pulse dust collector.
  • Page 7 3.1 The MultiBlast Australia blast cabinets do not require any special foundations , but should be installed on a flat, level surface to provide a stable installation. The system will be shipped in a semi-knocked down condition, with most smaller components transported within the cabinet itself.
  • Page 8 Position the dust collector within approximately 1.5m of the rear of the blast cabinet. Then simply slide the hose over the cabinet spigot, and clamp firmly in place using the worm drive clamps provided. Repeat this process with the dust collector inlet spigot. See figures 7 – 9. Figure 7 Figure 8 PRO800, PRO1200, PRO1500 &...
  • Page 9 Figure 11 Figure 12 For models with reverse pulse (RP) dust collection, position the 10-litre dust bin directly below the dust collector hopper, and connect the spigot on the lid of the bin to the dust collector using the wire reinforced hose and worm drive clamps provided. See figure 12. Re-connect the pneumatic control line tubing as follows –...

  • Page 11 3.9.2 Compressed air supply – All cabinet models (except PRO1000RP) require two (2) compressed air connections. One for the blast air supply and another for the dust collector cartridge cleaning system. The blasting system air connection point is located at the ball valve mounted on the air control valve assembly.
  • Page 12 3.10 Initial Set Up WARNING – Heavy lifting required. Take all necessary precautions and use appropriate lifting equipment to avoid injury. 3.10.1 Using the cabinet switch mounted on the front of the cabinet (except PRO1000RP), turn on the cabinet light assembly, and using the dust collector switch, turn on the dust collector fan.
  • Page 13 3.10.7 For initial operation, set the “on” duration time at 0.5 seconds, and the frequency “off” time at 3 minutes. Depending on the operating conditions, it will be necessary to adjust the pulse timer to suit the conditions after a period of operation. Refer to Section 5.0 Preventative Maintenance for further information.
  • Page 14 System Operation and Adjustments Check that that all cabinet and dust collector doors are in the closed position. Slowly open the blasting system isolation ball valve, which will send air supply to the foot pedal control. WARNING – The blasting system is now ready and will activate if the blast pedal is operated.
  • Page 15 The operator now stands in front of the cabinet and place their hands/arms into the left and right glove openings respectively. Take a firm hold of the nozzle holder assembly and depress the blast foot pedal with a foot. Blasting will now commence. Check closely the abrasive and air mix as it discharges from the blast nozzle.
  • Page 16 Preventative Maintenance Note: This maintenance schedule should be used as a general guide only. It does not consider any requirements which may occur on specific applications and working conditions. Daily 5.1.1 Drain any accumulated water from moisture trap bowl on the bottom of the blast pressure regulator.
  • Page 17 5.1.3 Drum dust collector – With the fan turned off, turn on the compressed air supply to the cartridge vibrator, and allow it to run for 2-3 minutes VIBRATOR CONTROL VALVE 5.1.4 Turn off the air supply, unlatch the drum lid and lift off the fan and cartridge assembly.
  • Page 18 5.2.3 Remove the blast hose coupling locking pin and disconnect the blast hose from the abrasive control valve. Carefully inspect the condition of both couplings and coupling gaskets. Replace the coupling and/or gasket if they are showing any signs of wear or grooving.
  • Page 19 WARNING – The filter cartridge will become heavy when fully dust laden. Use appropriate caution when releasing the filter cartridge from the hanger rod. WARNING – Breathing airborne dust from any abrasive media may cause lung disease or other serious injury. Always wear suitably designed respiratory protection when handling any abrasive media and/or waste dust, and when in the immediate area during any abrasive blasting operations.
  • Page 20 5.5.6 Check the condition of the urethane sleeve. The sleeve should be replaced if the sleeve ports have worn by more than 2mm. INSPECT URETHANE SLEEVE FOR WEAR 5.5.7 Carefully re-assemble Mini Micro valve, ensuring all seals and o rings are correctly seated and positioned.
