We offer Vacuum Blasting Machine. Blast cleaning with vacuum blasters have proceed to be a novel and highly effective method of cleaning ships' decks prior to applying protective coatings, without stopping other work on board. Likewise, shot peening is a solution to retard stress corrosion failure of ship hulls. By virtue of size and non movement of such jobs into the blast room, the blasting operation becomes difficult. Therefore, mobile closed circuit vacuum blast machine is the right solution.

We offer Vacuum Blasting Machine. It is a continuous operating grit blasting machine in which abrasive is automatically recovered instantly after impacting the surface. Powered by only compressed air, it needs no electricity and hence s suitable for site work. It removes light paint and scale very fast and the removal process is much better than chemical cleaning or wire brushing. No hazardous gas is produced so operator is completely safe. It is also fully suitable for finishing, etching, shot peening and surface preparation before coating.

a number of abrasives can be used such as metallic grit, glass beads, steel shots, plastic media and walnut shell etc. To meet specific requirement of cleaning and finishing. The impact of blast stream is highly controllable so that surface is not deformed or damaged. If a galvanized or anodized sheet is painted, the removal of paint can be easily effected without any harm to galvanized/anodized layer. Mounted on four castor wheels, it can be wheeled to required site. Instant recovery of dust and abrasive within the gun head ensures pollution free atmosphere, thus nearby operations can be performed simultaneously. The machine could be used for:

local rust removal at spots
grit / shot blasting.
shot peening.
paint removal for aircraft components.
cleaning before and after welding
surface etching.

We offer Vacuum Blaster p-15r is a high performance blast machine for quick removal of mill scale, rust, weld slag, old paint etc. It has it's own integral system of instant recovery of abrasive, dust and debris. No flying dust and abrasive to contaminate surrounding.

portable:

mounted on 4-wheels. It can be wheeled to job site. Needs only one man to operate.

blasting at high speed & high velocity:

the abrasive is pressure fed to blast gun, it is propelled at high force against work surface, thus increasing blasting output.

uniform cleaning & finishing:

abrasive is cleaned of dust and debris in reclaimer before being recharged from blast nozzle. This ensures uniform surface finishing all the time.

re-use of abrasive:

metallic abrasives like c.i. Grit and steel shots are used several times. Media recycling is automatic. Any type of abrasive except sand can be used depending upon surface to be cleaned and finish required.

easy control:

start/ stop control is located at blast gun for ease of operator.

safe operation:

operator need not wear air-fed helmet or to work inside the blast room. He is fully safe. He works in dust free conditions. Vacuum recovery is made possible either by pneumatic or by electric vacuum pump.

dust free operation:

dust, debris and used abrasive are recovered at the blast point. No flying of dust and abrasive into surrounding area. Work can go on uninterrupted e.g. Painting can be done along with blasting.

how it works:

the system of p-15r machine is shown here in diagrammatic cross-section; the arrows marked in green indicate abrasive flow from abrasive tank which is a pressure vessel, to blast gun and its return via vacuum hose to reclaimer. The arrows marked in red represent recovery of debris and dust from blast gun. Abrasive is pressure fed from abrasive tank :

to blast gun
blast gun remains in close touch with surface to be cleaned. After cleaning the surface, abrasive, debris and dust is vacuum conveyed to reclaimer.
where good reusable abrasive is air washed and sieved and then returned to abrasive tank (a) for reuse. Dust and debris is trapped by cyclone.
and dust collector
thus only clean air is discharged into the atmosphere. Reverse air flow (vacuum) is created by compressed air ejector or by vacuum pump.

blast gun pressurizes stream of abrasive at the work surface and automatically transfers all dust, debris and used abrasive to reclaimer via a vacuum hose. Four castor wheels facilitate movement along work surface. A nylon brush surrounds the gun body to prevent escape of abrasive and dust.

We offer Vacuum Blasting Machine. It is a small handy blasting tool for light work, touch-up cleaning and maintenance job. It does blasting in dust free conditions.

unit weight: 3.5 kg.
Abrasive charge: 1.8 kg.
Total weight: 5.3 kg.

no special skill required to operate.

small enough to be fitted through tank manhole, or into hard to get at areas.

ideal for locations where abrasive must be fully contained i.e. Machinery area, electronic equipment etc.

swivel head allows blasting at any position-overhead, side-ways, down hand etc.

most common re-useable abrasive may be used, such as shot and grit, aluminium oxide etc

one-man operation equals three man cleaning by wire brushing, disc sanding or other hand cleaning methods.

always ready to use. Attach to 19 mm air line and start blasting.

no electrical connections. Requires 33 to 60 cfm at 90 to 100 psi pressure. Best pattern approx. 31.8 mm wide.

a while metal surface is obtained suitable for any recoating.
