Mobile blasting systems
The MVS² is a mobile vacuum blast machine for detail work: a 10 litre hopper, three brushes, and a gun that projects the abrasive and extracts it in the same movement. For larger surfaces and continuous work there are the closed circuit machines from 9 to 48 litres.
The technique
A brush around the nozzle seals against the surface. The gun extracts more air than leaves the nozzle, so everything you blast off travels inwards. The abrasive passes through a separator and returns to the hopper cleaned.
You do not have to cover the surroundings. That shortens the preparation, and colleagues keep working next to you.
You sweep nothing up and you dispose of no contaminated abrasive. The difference with the heavier closed circuit machines is size: the MVS² is meant for local work, with a 5 metre hose.
The installation passes through an ordinary doorway and works in an occupied room or one that stays in service.

PharmaThe set
The package is put together for the work itself, hoses and couplings included. There is nothing to source on the side.
Mobile, with an integrated recovery system, a 10 litre hopper and a filter pressure regulator.
Trigger control, a boron carbide nozzle, and three brushes for a flat surface, an internal corner and an external corner.
Up to 1,300 l/min, 15.5 kW and 76 dB(A), with an external aftercooler for condensate free compressed air.
Blasting and extraction hose of 5 m, air hose of 10 m with safety couplings, plus visual and hearing protection.
Applications
The MVS² is a micro blasting system. It is at its best where the area is small, or where the surroundings must stay clean.
Specifications
The complete installation was reviewed for safety and found EC compliant. On delivery you receive the declaration of conformity for the assembled system.

|---|---|
| Abrasive hopper | 10 litres as standard |
| Extraction | pneumatic venturi, built into the unit |
| Recovery | integrated, the abrasive circulates in a closed circuit |
| Blasting pressure | usually 2 to 6 bar, depending on the application |
| Blasting gun | brush gun with trigger control |
| Blasting nozzle | boron carbide |
| Brushes | three pieces: flat, internal corner and external corner |
| Pressure control | filter pressure regulator for the working pressure |
| Blasting and extraction hose | 5 m |

| Compressed air | external aftercooler for condensate free air |
| Conformity | the applicable European directive for machinery |
| On delivery | EC declaration of conformity for the assembled compressed air system |
The figures come from the technical data sheet of the MVS². Extraction is pneumatic, so no separate vacuum cleaner is needed.
| Type | Nature | Bulk density | Hardness (Mohs) | Grain size | Colour | Packaging |
|---|---|---|---|---|---|---|
| Corundum | Al₂O₃ | 1.59 to 1.98 kg/l | 9 | 62, 74, 125 and 149 microns | brown | 25 kg, pallet of 1,000 kg |
| Glass beads | SiO₂ and Na₂O | 1.50 kg/l | 5 | 40 to 70, 70 to 110 and 90 to 150 microns | white | 25 kg, pallet of 1,200 kg |
| Ceramic beads | ZrO₂ and SiO₂ | 2.30 kg/l | 7 to 9 | 70 to 125 and 125 to 250 microns | white | 25 kg, pallet of 500 kg |
Other types and grain sizes are available on request. The fine grains are meant for soft substrates, the coarser ones for rust, paint and hard surfaces.
Consumables
Because the abrasive circulates in a closed circuit, how long the grain lasts matters. Ceramic beads are the hardest and the heaviest of the three. The fine grain sizes are meant for soft substrates, the coarser ones for rust, paint and hard surfaces.
Service
The brushes, the nozzle and the hoses wear under intensive use. The brush seals against the surface, so that is the part you replace most often.
You have your installation checked by our own technicians, with no intermediary. You set out the visits in the contract.
Maintenance, repair and spare parts you arrange directly with Phibo. Nozzles, brushes, hoses and filter cartridges are in our own stock.
We show your people how to match the pressure, the abrasive and the brush to the job in front of them.
Tell us what you are treating and where it stands. A proposal with the right set and the right abrasive follows after that.
