 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 (A) to Blast Gun (B). Blast
Gun remains in close touch with 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 Abrasive Tank
(A) for reuse. Dust and debris is trapped by
Cyclone (D) and Dust 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 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.
MEC SHOT 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.
