Spray gun for the compressor: choice, characteristics, reviews

During the repair, you may have to paint a large enough or complex surface. Naturally, using a brush will make the work physically difficult and time consuming. It is best to choose a spray gun for the compressor, which will greatly help you in the task.

What is the device?

So, this is a special device that is intended for fast and maximum quality coverage of complex or large surfaces. Such an aggregate allows you to significantly reduce the time that you planned to spend on repairs.

Please note that almost no other painting tool will be able to cope faster and better. The device uses the method of spraying the material under pressure. In this case, the paint can be of different types: water-emulsion, water-water, oil and even acrylic.

Product Advantages

The pre-selected airbrush for the compressor has the following advantages:

1. Reduction of time for repair work.
2. High quality coating.
3. Significant increase in the area of the surface to be treated.
4. No need for professional skills.
5. Reducing the consumption of paint and varnish material.
6. Affordable cost of the device.
7. A variety of design types, allowing you to choose the most suitable option for work.

However, before you buy the device, you need to properly choose a spray gun for the compressor.

Product design

In almost all cases, the structure of the apparatus is similar. In the pneumatic device there must necessarily be a compressor, without which its operation is impossible. The paint is poured into a special tank, to which a spray nozzle joins the hose.

If the device is electric, then in addition it is equipped with an electric pump, which creates pressure. Another important element is the spray gun nozzle. In addition to these elements, the unit is equipped with a knot for adjusting the air supply.

Product Specifications

If you need to buy an airbrush for a compressor, you need to know the features of the device. Technical characteristics can be summarized as follows:

1. The power of the unit is from 280 W.
2. Weight - from 1 kg and above.
3. The capacity of the vessel for paint is 600-800 ml.
4. The productivity is about 300 ml / min.
5. The size of the nozzle is 0.8-3 mm.
6. Working pressure is about 2-3 bar.
7. Air consumption is 200-500 liters per minute.

Varieties of spray guns

First of all, we can distinguish such types of devices as industrial and household. The first type can be used in large industries, and the second type - at home. Another classification of these devices can be by the method of spraying paint: airless, air, in the electrostatic field, combined.

According to the principle of operation, the aggregates can be divided into:

• Pneumatic . Their feature is the work on compressed air. That is, you have to install a compressor equipped with a receiver. Without it, the device can not be operated. The principle of the product is that compressed air, under strong pressure, breaks the coloring liquid into very small elements. Then they are forcefully pushed out through the sprayer.
• Electric . The operation of such a device does not require compressed air. That is, the compressor for painting with a spray gun is not required in this case. As for the required pressure, it is provided by a built-in pump. Compared with the previous type of device, this one has some drawbacks. For example, it creates a lot of noise, and also does not provide high-quality breaking of the paint into particles. However, Bosch spray guns are distinguished by their high practicality and good technical characteristics.
• Mechanical . This type of device is different in that the pressure here has to be pumped manually.

Features of the choice of the compressor

This is a very important issue, since the quality of the work, its cost and duration depends on the correctness of the purchase. The compressor for the paint spray gun (its price ranges from 6000-11 5000 rubles) should be selected, taking into account such parameters:

• Engine power. This criterion is probably the most important. The standard parameters are 1.2-1.8 kW. Small power units can be used for domestic work, for painting small surfaces. High-powered products are used on an industrial scale.
• The volume of the receiver can vary from 24 to 500 liters. For domestic use, quite a small amount is enough.
• Pay attention to the working pressure of the device. If you do not need to paint too large surfaces, and the device is small in size, then the parameters may not exceed 2-3 bars. For industrial production, products with a pressure of 8-10 bar or more are used.
• An important parameter is the performance of the compressor. It shows how much compressed air per minute the given device can give out. Naturally, the quality of the coating obtained depends on this. The more compressed air comes out, the more uniform the layer is.

An important condition for choosing is the availability of additional qualities. For example, it's not at all superfluous to have an automatic system for emergency shutdown of the device during overloads. The installation of a pressure gauge with the possibility of adjusting the working pressure is also welcome. An important element in the spray gun is a filter that does not allow the nozzle to clog, as well as a fan for cooling the product. As you can see, it's not easy to choose compressors and spray guns. Bosch is one of those companies that try to make this stage as easy for buyers as possible.

Features of the choice of spray gun

So you got to the last question. Now you will learn how to choose a spray gun. Buy it should be based on such criteria:

• Strength of the case. It's better if it's metal. Plastic can quickly break if accidentally dropped.
• The nozzle cover must be made of stainless steel, as it is constantly in contact with the liquid.
• Carefully inspect the gaskets to ensure that they seal the connections securely.
• Convenient location of the paint tank. For example, if its consistency is very viscous, then it is better to use a container that is on top.

There is an airbrush with a remote compressor, but it is not always convenient to use. Here are some tips, compiled from the reviews of those who already use this device, which will also help you decide the choice:

• Pay attention to the width of the torch.
• Weight of the device.
• Availability of additional components.
• It is best to buy a pneumatic device, because it is more easy to use, and also cheaper.
• Really appreciate your needs. Perhaps you do not need a very powerful device.
• Before buying it is better to preview customer reviews, the parameters specified by the manufacturer.

Now you know how to choose a spray gun. Good luck.
