Recirculating abrasive sandblasting guns - time-tested and quite convenient solution . To select the correct tool, you must familiarize yourself with the overview of recuperative guns, as well as the features of recirculation guns without sand loss.

Peculiarities

Recirculating abrasive blast guns are designed to use a variety of abrasives. For him, you can apply:

• nickel slag;
• cheaper copper slag;
• quartz sand (after preliminary washing);
• aluminum oxide (marketed as corundum).

The choice between these abrasives is due to economic and technological considerations. The recirculating pistol has an important feature - it consumes much less abrasive substance than conventional counterparts . Various attachments may be included in the delivery. The machines don't just work without wasting sand - they guarantee superior performance through carefully designed nozzles.

Optimal precision is maintained in guiding particles to the target area.

Devices with such a system do an excellent job with:

• elimination of small corrosive foci;
• wing flanges processing;
• work with rims, sills.

Popular models

A recuperative pistol such as " Russian Master PS-10 ". It fully meets the needs of novice craftsmen and experienced professionals. The device is versatile and can work with a wide variety of abrasives. But it should be noted that the PS-10 model is present not only at the “Russian Master”. At least one other manufacturer has it.

We are talking about Voylet PS-10. Its characteristics:

• bayonet connection;
• working pressure 8 atmospheres;
• air fitting 1 / 4F;
• supply of abrasive from the internal tank;
• equipping with a blister;
• curb weight 650 g.

A good alternative is deservedly considered Fubag SBG142 / 3, 5 110115 … With its own weight of 500 g, this pistol consumes up to 142 liters of air per minute. Working pressure reaches 3.5 atm. The basic delivery set includes a box. The rapid connection, that is, the euro, is performing very well.

Another decent model is the Walmec SuperMistral 50300. Highlights:

• weight 2, 4 kg;
• pressure up to 8 atmospheres;
• connection by means of a thread;
• weight in packing 2, 98 kg;
• the ability to work for a long time without stopping.

Nuances of choice

The pressurized look of sandblasting guns is serious and professional. The abrasive under the pressure of a stream of compressed air will be pumped through the hose to the nozzle. Inside the line, the substance is accelerated and delivered to the desired location. A compressor with a capacity of over 5000 liters of air per minute is required for normal operation.

Injection solutions are rare because they have little compatibility with the very idea of full closed circulation.

Nozzle material is critical … Under the action of an abrasive flow, it will wear out heavily. The durability of the entire product depends on the durability of the channel. The larger the capacity, the longer the battery life. However, this makes the structure heavier and less user-friendly.

Other nuances:

• better to be able to hang the device;
• for complex work, a working pressure of at least 10 atmospheres is desirable;
• for decorative manipulations, a pressure of 3 to 5 atmospheres is quite enough;
• it is useful to consider the convenience of holding the pistol (or rather, its handle).
