Best sandblasters – Top 6 popular models in 2021

Those who are constantly faced with the need to clean metal surfaces know that this task can be solved in different ways. The most labor-intensive, time-consuming, and exhausting is considered the use of hand tools. To minimize the time spent and improve efficiency, sandblasting tools are used. The main task is to choose the best sandblaster.

Machine description

These tools differ in characteristics and principles of operation. However, they contain the same constructional elements: 

  1. compressor; 
  2. gun with a nozzle; abrasive tank; 
  3. control device; 
  4. connecting hoses; 
  5. storage tank. 

The most important element is the compressor, which serves to pressurize the air stream. Divided into units of low power, medium-power, and high power. Functioning is controlled by automatics, switching the device on and off, regulating the pressure indicator.

The best sandblaster and most expensive models are equipped with compressors and a special system that allows you to turn them off in case of failure, as well as in case of power surges.

The advantages of automation are as follows:

  1. The full stop of the device in case the operator’s hands miss the nozzle.
  2. The possibility of transferring the device in the working and idle mode.
  3. Control of additional functions.
  4. When the level of sand decreases, it begins to signal.

What to look for when choosing a model? On the quality of assembly and dimensions of hoses for air and sand, as well as for the output of the abrasive component. It is from these parameters directly depends on the power of the device and performance, as well as the quality and duration of the operation.

Features and operating principles

Sandblasting units are used to remove various kinds of contaminants from surfaces. Manufacturers produce several types of units that are similar in the principle of operation: thanks to compressed air, the abrasive agent or sand flies out of the nozzle at great speed, crashing into the dirt and effectively removing it. These machines are used to clean buildings, metal structures from rust, old paint, dust, and dirt. Sandblasters are divided into types, depending on the type of action and power. Thus, there is a division into the following apparatuses:

TypesFeatures
Low capacity Capacity up to 30 liters. Scope of application - hard-to-reach places and when working at considerable heights. Not able to work for a long time, you must regularly give the device a rest.
Medium power.  Capacities from 50 to 140 liters. They are characterized by the lack of a powerful compressor. Used in medium and small productions.
High-powered.Presence of not less than 20 liters capacity. Used for big amounts of work. With this stationary device, huge contaminated areas are processed.

Based on the type of action, the devices are: 

  1. Pneumatic (pressure). Quickly and efficiently cope with heavy dirt or a thick layer of rust. Ready to cope with any amount of work, so they are deservedly popular in large enterprises. A distinctive feature of these devices is the following: compressed air is not only fed into the sand blaster guns but also into the abrasive dispenser, which significantly increases the speed of the released air jet. 
  2. Vacuum. The principle of operation is as follows: the abrasive substance is fed to the contaminated base, immediately picked up by the vacuum, and is again thrown on the contaminated area. Can be used for certain activities involving possible damage to surfaces close.
  3.  Injection. Distinctive feature: air and abrasive mixture are fed through different hoses. The power of the hand held sand blaster is small, so the device is not able to cope with significant pollution on large territories. However, for delicate cleaning, it is the most acceptable option.

Options for sandblasting

Thanks to these units, it is possible to tidy up different types of surfaces using: 

  1. Light cleaning – removing minor rust and scale. The result is a clean base, but minor contamination may remain in hard-to-reach areas. 
  2. Medium cleaning – involves more thorough measures to remove paint, dirt, and rust. Result: spots of corrosion remain. 
  3. Deep cleaning, which perfectly cleans all kinds of dirt. It is used in case the next stage of the work will be the application of paint.

Areas of application of sandblasters

The most common industry – body repair. This technique helps to quickly and effectively free the surface from old paint, rust, grease, and other contaminants. Often the device is used in the repair of discs: if the part is peeling, crumpled, or damaged, then before proceeding to its restoration, first produce a high-quality cleaning, and then – painting.

What are the advantages of a sandblaster? The result of grinding metal with this tool is unique, which cannot be achieved in manual mode. This method removes even the most pitting corrosion elements “hidden” in pits, small pores, and microcracks, which allows you to minimize the process of rusting of the metal base. Products cleaned in this way last much longer and are less susceptible to corrosion. As for the surface, it is remarkably smooth. If there are no scratches, the primer and paint perfectly cover the parts.

In addition to repairing cars, the sandblaster is widely used in:

  • furniture production;
  • ship repair, and shipbuilding;
  • major repairs of construction projects;
  • woodworking;
  • cleaning the bases from brick and concrete;
  • in the process of engraving metal;
  • creating intricate patterns on the glass;
  • pretreatment of products before applying thermal spraying and using electroplating operations;
  • in matting ceramics and glass.

Powerful devices made of high-strength material and endowed with special functions through the use of all kinds of nozzles are used for drilling holes, grooves, and slots. Design fantasies with the use of such a unit allow you to treat the surface in such a way that the material “aged” and acquired a vintage look.

Tips from experts on working with the best sandblaster

It does not matter what company it is better to buy the product, and whether it is in the rating of quality products, Russian or Chinese production, budget, or at a significant price. The main condition for work is the observance of safety precautions. Branded tools can cause damage to human health, provoking the development of serious lung diseases, or lead to injury due to the substantial rate of abrasive discharge from the nozzle. To avoid unpleasant situations and keep your health, it is necessary to heed these recommendations:

  1. Wear closed shoes made of thick material before work. 
  2. Do not forget to wear high-strength special overalls. 
  3. Wear a protective helmet. 
  4. Protect your hands with leather gloves. 

Some “daredevils” in the open air wear only a normal respirator, but the best option would be the availability of a helmet with an autonomous air supply. If the action is performed indoors, this attribute is mandatory. It is worth considering that powerful units are not silent, so to avoid damage to the hearing, you should wear earphones with sound-absorbing functions under the helmet. They can also be built into the helmet.

Features of the premises for working

with the unit

The effectiveness of any work directly depends on the proper organization of the workplace. Sandblaster will operate safely and reliably in a room with a normal index of humidity. Otherwise, the process can be significantly delayed, and productivity – reduced. If the humidity is too high, measures are taken to reduce the figure.

For this purpose, special dryers are installed at the site. The best manufacturers produce popular models equipped with such functionality. Of great importance is the purity of the air. This is achieved through the use of filtration systems. As a rule, are already built into the devices, which makes it possible to free the air from particles of dust, dirt, oil. If the unit functions in a closed space, then the object should be able to quickly and qualitatively clean the sand. The optimal option – a complete tightness of the room, where the remaining sand will fall into special reservoirs through the holes made in the floor. After preliminary sifting can be reapplied.

How to choose a device

According to buyers, it is necessary, first of all, to pay attention to the weight of the product. The design should not be heavy. Besides, it is desirable to equip it with a chassis to facilitate transportation. As for the tank, its characteristics must meet international standards on safety issues. When buying, you need to ask the seller for a certificate of inspection.

Which product is better to buy, depends on the preferences of the craftsman. But certain selection criteria must be taken into account. And the brand and rating are not fundamental. Of great importance is the device of the pipeline. It is worth bearing in mind that the simpler it is, without fittings and bends, the more powerful the unit. It is necessary to pay attention to the diameter of the hole. The optimal indicator is 1.26 inches or more. 

In order not to make a mistake when choosing, it is necessary to conduct a review of manufactured products, read the reviews. It is necessary to pay obligatory attention to such moments: 

  • the ability to function with different granular material;
  • high reliability of assembly; 
  • the presence of an automatically closing filling valve or flap; 
  • the presence of a feeding container; 
  • equipped with a metering device for abrasive material, shut-off valves for air inlet and outlet; 
  • presence of an inspection hatch.

A powerful compressor is supposed to have a nozzle with a large diameter. Only in this way it is possible to increase productivity. To choose the right air gun, it is worth paying attention to the following recommendations: 

  • treatment of wood, brick, or concrete is carried out by a handheld sandblaster with high performance, but low power of the jet; 
  • metal and glass are better to clean with a strong jet of abrasive. 

There are several ways to buy a device of this type. You can also go to a specialized store, where you can purchase the selected equipment.
