Blast Rooms are generally provided with AW-501R and AW-1001R models. During the blasting process, the mushroom valve and exhaust valves are closed, the vessel is pressurized and the media is forced out through the feed valve to the nozzle. When the blasting ceases, the vessel is depressurized by opening the exhaust The valve. remains vessel depressurized except when blasting is in process. The remote control valve provide in the system releases the pressure, stopping the blasting process thereby ensuring safe working conditions for the operator in case the hose and nozzle drops accidentally.

AUTOMATIC FILLING VALVE :
The machine is provided with automatic mushroom valve (Filling Valve) for quick refilling of abrasive
Salient Features of Portable Abrasive Blasters
The long & short series convergent-divergent tungsten carbide lined blasting nozzle ensures high velocity, evenly distributed blast pattern & higher blasting output and provides lower wear, longer life and greater resistance against breakage.
ABRASIVE CONTROL VALVE :
The blast hose is highly abrasion resistance with improved mixing valve outlet for longer life, high flexibility with lower bend radius & light weight and electrically antistatic for safe operation.
ABRASIVE SIEVING :
A wire screen is fitted with pneumatic vibrator to sieve abrasive to avoid blast line choking
ABRASIVE TANK CONSTRUCTION :
Abrasive tank is fabricated from tested quality steel plate in accordance with IS-2825 and hydraulically tested at 250 psi.
AUTOMATIC EXHAUST VALVE :
It vents outlet air and thereby machine is depressurised instantly. Valve opens automatically with stop of air supply to machine and vice-versa.
AIR FILTER & PRESSURE GAUGE :
An online air filter and pressure gauge is provided
BALL VALVE
The machine is fitted with ball valve having stainless steel ball (An anti-corrosive material) to ensure full air flow without pressure loss.
