Reliable compressor for painting a vehicle allows you to carry out high-quality processing of the car yourself. Another thing is that in the modern market, among a wide range of products, it is not so easy to choose the optimal model. The quality of the coating application and ease of use depend on its parameters. Consider the characteristics of popular modifications, as well as consumer reviews of some manufacturers.

Purpose of the unit

The paint compressor is a universal device that mixes air and gas mixture under pressure. During operation, the apparatus prepares the compressed composition for subsequent use. Modifications with a low pressure indicator and a small chamber do a poor job, leaving streaks and streaks on the car body. Such versions are usually used for pumping wheels.

Powerful compressors for car painting also perform a number of other functions:

• Can be aggregated with pneumatic tools and diagnostic instruments.
• Used for grounding during repairsauto.
• Act as anti-corrosion sprayer.
• Designed for blowing and cleaning various components or parts.
• Participate in the process of washing and polishing the vehicle.

Piston and screw models

The piston compressor for car painting is a fairly reliable and productive device. With weak characteristics, such models are not suitable for applying an external coating. With these parameters, aggregates are most often used to mask a flaky surface.

The advantages of the device are low cost and ease of replacement of parts. Most elements can be repaired without dismantling the body. Another advantage of the device is low power consumption. The principle of operation of the mechanism includes the operation of a diesel and electric drive, which contributes to the transformation of the received electricity into an air compressed mixture. Through a special tube, the mechanism is activated.

The paint screw compressor is used to apply paint to the car body. The device is easy to operate and maintain, and economical. The pressure in the working compartment is created by means of synchronous scrolling of the parallel gates located in the body of the device. The design provides for chambers that serve to reduce and increase pressure, and there is also an automatic protection of the device control. It allows a constant supply of air fromthe possibility of setting the required mode of operation by the operator. Such units are mainly used in large enterprises where uninterrupted long-term use is required.

Other modifications

What other compressors are used for painting, we will consider further. Here are the following models:

1. Mechanisms without oil and their analogues, which function by forcing a clean air mass. It is not advisable to use them for treating a car body, since a large amount of hydrogen is observed in the supplied composition, which is fraught with the appearance of bubbles on the treated surface.
2. Turbine air compressors for painting are ideal for bodywork. The mechanism has a high performance index. However, he is not very mobile and has an elementary control unit.
3. Combined units. They are compact in design, combine the qualities of piston and oil devices, and do a good job of applying paint to a vehicle.

Recommendations

To correctly determine which compressor is preferable for painting a car, you should study the list of technical characteristics of the device and its capabilities. To eliminate minor scratches and chips, a model with low power and a small tank volume is quite suitable.

However, in this case, it is unlikely to get a perfect coating without streaks and smudges. When choosing a mechanism, consider the typeatomizer. We'll talk about this later.

Spray guns

Paint spraying devices also have a certain qualification. Among the most popular versions, the following modifications are distinguished:

1. Low-pressure apparatus with a large volume of the HVLP type. When working with this device, the paint is removed outside the surface to be painted in a small amount. The disadvantage of this category of spray guns is the ability to work only with powerful compressors for painting, which produce at least 360 liters of air volume per minute. Engine operation is carried out only in increased mode, which increases oil consumption and requires the use of additional filter elements.
2. HP nebulizer is high pressure oriented, has many advantages. The disadvantages include the release of excess paint outside the object in a decent amount. As a result, a vortex is created, after which the remains sit on the object being processed.
3. LVLP. This spray gun works with low pressure and small working tank volume. The advantage of the system is a stable low pressure at the outlet and inlet, and excessive paint output does not require a particularly powerful supercharger.

Criteria for choosing a compressor for painting

When choosing a unit, certain parameters related to the characteristics of the device and its final purpose should be taken into account. For professional use of the tool, it is advisable to choose an oil piston unit, the power of which is at least 8 bar. Whereinthe volume of the receiver can vary up to 100 liters.

The result is an output of the working mixture of about 330 liters in 60 seconds. It is unlikely that you will be able to completely paint a car with high quality, but it is quite possible to mask surface damage and scratches.

Professional work

What kind of compressor do you need for professional car painting? This will require more powerful and productive mechanisms. Their strength must be at least 10 atmospheres with the ability to process 200-500 liters per minute.

Specialists will need a single-cylinder analogue with a set of 330 l / min. and a 100 liter receiver. Capital painting of a car is best done using fixtures with parameters from 500 l / min. - 200 l The cost of such a unit will be much more expensive. If the device is used frequently and in individual business, it pays for itself pretty quickly.

Manufacturer Reviews

In their responses about manufacturers, users highlight several brands that are distinguished by reliability and high performance. They are listed below:

1. TOP Aero. This Chinese compressor has a capacity of 1.8 to 2.2 kW, a 50-liter tank, and can be equipped with one or two cylinders.
2. A good option is ABAC Pole Position Plus OM 231. Its parameters are: capacity - 24 liters, motor power - 1.5 kW, performance is 230 l / s with a weight of 25 kg.
3. FIAC FX 95. Brief characteristics: volume - 24 l, weight - 27 kg, power -1, 1 kW, capacity - 205 liters per minute.
4. In their reviews, users also speak positively about the Schneider Druckluft A 111 002 brand. This unit produces 200 liters of usable volume per minute, has a power of 1.1 kilowatts, and weighs 20 kilograms.

DIY painting compressor

A home-made device for treating car body paints will be cheaper than a store-bought version. You will need an engine of suitable power, for example, from a refrigerator. In addition, it will be necessary to purchase a receiver, a fum tape, a pressure gauge, a fitting, a pressure control switch, an adapter and a tap for the pump. All parts are connected securely to each other. Then the pressure in the system is checked. If everything is assembled correctly, this figure will be 3.5 Bar. Next, the frame is welded, after which the gearbox and dehumidifier are attached.

Helpful tips

To find out which compressor is needed for painting, you should pay attention to the recommendations of specialists. They advise to use reciprocating air compressors. These units have proved to be the most effective, both in private garages and at service stations.

Oil-free variations of this type are ideal for the most basic car maintenance procedures. Oil models are used for the above procedures, and are also used as devices that allow you to paint with high qualityvehicle. In turn, they are divided into belt modifications and direct drive versions. Mechanisms with a belt are more reliable: the motor runs at a lower frequency, the diameter of the flywheel is slightly larger than the size of the shaft, and a well-thought-out air exhaust system is provided.

Summary

For those who like to craft in their garage, an oil compressor with one cylinder and a receiver volume of up to 100 liters is suitable. The productivity of such a device will be about 300 liters per minute. For those who are going to be engaged in professional car painting, it is recommended to purchase models with a capacity of at least 500 liters (with a working pressure of 10 atmospheres).
