P-15R

How it works
The system of P-15R machines is shown here in diagrammatic cross-section. The arrows marked in green indicate abrasive flow from an abrasive tank which is a pressure vessel, to blast guns and its return via vacuum hose to the reclaimer. The arrows marked in red represent recovery of debris and dust from blast guns.

Abrasive is pressure fed from an abrasive tank (A) to blast guns (B). Blast gun remains in close touch with the surface to be cleaned. After cleaning the surface, abrasive, debris and dust is vacuum conveyed to reclaimer (C) where good reusable abrasive is air washed and sieved and then returned to the collector (E). Thus, only clean air is discharged into the atmosphere.

Reverse air flow (vacuum) is created by compressed air ejector or by vacuum pump (F). Blast guns pressurizes the 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 the work surface. A nylon brush surrounds the gun body to prevent escape of abrasive and dust.

Vacuum Blasting Machine P-15R
Vacuum blaster P-15R is a high performance blast machine for quick removal of mill scale, rust, weld slag, old paint etc. It has its own integral system of instant recovery of abrasive, dust and debris. There are no flying dust and abrasive to contaminate the surroundings.

Portable:

• Mounted on 4-wheels it can be wheeled to job sites. It needs only one man to operate.
• The abrasive is pressure fed to the blast gun and is propelled at high force against work surfaces, thus increasing blasting output.
• The abrasive is cleaned of dust and debris in the reclaimer before being recharged from the blast nozzle. This ensures uniform surface finishing all the time.
• The metallic abrasives like CI grit and steel shots are used several times. Media recycling is automatic. Any type of abrasive except sand can be used depending upon the surface to be cleaned and the finish required.
• The start / stop control is located at blast gun for easy operation.
• The operator need not wear air-fed helmets to work inside the blast room. He is fully safe and works in dust free conditions. Vacuum recovery is made possible either by pneumatic or by electric vacuum pump.
• The dust, debris and used abrasive are recovered at the blast point. Work goes on uninterrupted, e.g., painting can be done along with blasting.
