Salient Features Of P7 150 Abrasive Blasters

When you buy Portable Pressure Blaster, consider the following features, Many of these are either totally absent in competitive makes or are supplied at extra cost. P7 is a package unit… Complete for operation.

The machine is provided with automatic mushroom valve (Filling Valve) for quick refilling of abrasive.

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.

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.

The machine is fitted with pinch valve with hand wheel to control the abrasive flow through blast nozzle.

A wire screen is fitted with pneumatic vibrator to sieve abrasive to avoid blast line choking.

Abrasive tank is fabricated from tested quality steel plate in accordance with IS-2825 and hydraulically tested at 250 psi.

It vents outlet air and thereby machine is depressurised instantly. Valve opens automatically with stop of air supply to machine and vice-versa.

An online air filter and pressure gauge is provided.

The machine is fitted with ball valve having stainless steel ball (An anti-corrosive material)to ensure full air flow without pressure loss.

Applications

To blast clean the surface of floor tiles, slates, sand stone, marble chips for proper bonding with surface
Creating design, surface etching & engraving on different types of stones.
Portability of machine helps it for cleaning huge monuments in a very less time..
Site blasting of huge components like heavy structure, tanks, pressure vessels, bridges, towers, pipes etc. prior to repainting.
Descaling, deburring & deflashing of forged and die-cast components.
Quite useful for overhauling, general maintenance and repair work in cement, chemical & gas plants.
Steel fabrication can be de-scaled after welding or de-rusted, ready for painting on site using different media depending on finish required.
Removal of heat treatment scale, corrosion, rusting, scale formation, welding flux, carbon & minuscule in steel components.
Blast cleaning to remove scale, corrosion rust & paint from deck, hulls & super structure etc
Widely used in handicraft industries to give new look to metal as well as wooden items.

It is recommend to perform blasting operation inside Blast Room which consist of an Enclosure, Dust Collector, Recovery System (Semi / Automatic), Work handling system etc. The size of Blast Room is mainly governed by size of Job, No. of operators etc.

A single chambered working model recommended for very high productivity by blasting. The abrasive tank is made as per customer requirements. Tungsten carbide nozzle measures 10 mm and the blast hose 32 mm with length 10 meters. Its cleaning rate is 15-19 sq. meters. It has the pressure feed system of abrasive propelling which results in higher production rates. Pressure vessels are tested to 250 psig. The blast nozzle’s special design and tungsten carbide lined, result in long service life. It is equipped with high static and low weight blast hose. The remote control ON / OFF is at the operator’s hand and requires no electric connection. It is easy to handle and tow.

A medium capacity model, recommended for jobs like fabricated parts, castings, stones, glass etc. The abrasive can hold up to tank 85 litres and the tungsten carbide nozzle is of 6 mm. The blast hose is 19 mm with length 5 meters and a cleaning rate of 5-9 sq. meters.

Automatic Filling Valve: The machine is provided with an automatic mushroom valve (filling valve) for quick refilling of abrasive.
T. C. Lined Long Venturi Nozzle: The long series convergent-divergent tungsten carbide lined blasting nozzles ensures high velocity, evenly distributed blast patterns and higher blasting output. It provides lower wear, longer life and greater resistance against breakage.
Blast Hose: The Blast Hose is highly abrasion resistant with a longer life, high flexibility, lower bend radius, is light weight and electrically antistatic for safe operation.
Abrasive Control Valve: The machine is fitted with a pinch valve which has a hand wheel to control the abrasive flow through a blast nozzle.
Abrasive Sieving: A wire screen is fitted with a pneumatic vibrator to sieve abrasive and avoid blast line choking.
Abrasive Tank Construction: An 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 air and thereby the machine is depressurized instantly. The valve opens automatically with stoppage of air supply to the machine and vice-versa.
Air Filter and Pressure Gauge: An online air filter and pressure gauge is provided.
Ball Valve: The machine is fitted with ball valve, having stainless steel balls (an anti corrosive material) to ensure full air flow without pressure loss.

The internal pipe cleaning tools can clean the inside surface of pipes of 51 mm to 914 mm inside diameters and up to 12000 mm long. It cleans completely around 360 degree interiors of pipe. It removes stubborn rust, carbon, old paint etc. The internal pipe cleaning tool operates with any high capacity pressure blasting machine such as P7-501, P7-1001.

It places complete ON / OFF control of the machine in the hands of the operator at blast nozzle. It saves abrasive consumption when operator changes position or performs spot blasting and provides added safety to operator and other personnel in the area. Machines fitted with remote control system are designed with “R” such as P7-301R, P7-1001R and so on.

Wet Head is recommended for economical wet, dustless, blast-cleaning with P 7 type blast machines in jobs such as cleaning structures of stones, brick, concrete etc. Wet blast nozzle is attached to the abrasive blast nozzle to provide wetting of dry air-abrasive streams prior to its forceful discharge from the nozzle opening. It also serves to wash off finished surfaces with a clean pressurized air-water stream after shutting off the abrasive supply.
