HVLP spray guns: overview, specifications, models and reviews

Without a paint sprayer today can not do anya workshop or an enterprise whose activities involve the application of liquid formulations. A compact tool allows you to cover the target surface with a paint and varnish solution without excessive costs and maintaining the optimum uniformity. There are different technologies for implementing this device, one of which is based on HVLP spray guns, characterized by low pressure maintenance. This is the most powerful version of the pneumatic gun for paint, which is widely represented in the Russian market.

Features of HVLP system models

The HVLP technology was developed long ago andwas introduced into the spray guns as a way of reducing the amount of paint consumption. The fact is that the spraying equipment suffers from one drawback: when forming a working aerosol cloud, a significant part of the smallest drops of the composition settle. To minimize this effect, use HVLP spray guns with a pressure of 2 bars at the inlet and 0.7 bar at the outlet. The design of the instrument reduces the value of the inlet pressure, as a result of which the spray head differs with a lesser intensity of the paint and varnish mixture. As a result, a large proportion of the released particles settle on the target surface.

Traditionally, spray guns are associated withpneumatic equipment, but there are also electric models. In terms of performance, they generally correspond to pneumatics, but the motor is powered only from the mains. This drawback is compensated by the fact that the HVLP electric spray gun has a more compact size, which is convenient when performing large amounts of work.

Main characteristics

The average operating pressure range varies fromThe above limits range from 0.7 to 2 bar. But there are also models that support the level of 3-6 Bar. These are already professional devices that are used on production lines. The productivity of the tool depends to a large extent on the pressure. That is, the air flow required for spraying. For this indicator, the models occupy a wide range of values ​​from 50 to 250 l / min. By the way, the equivalent of air consumption as an indicator of power and productivity in the case of electric vehicles is the engine's power potential. It averages 200-600 watts. In this case, both the electric model and the air gun HVLP have the same paint tanks. The capacity of the tank can be 0.8-1.2 liters.

Model Sata Graph 3

This is a premium paint sprayer,designed for delicate art work. The HVLP system in this device allows you to fine-tune the parameters of the working jet with the subsequent application of narrow lines and points. However, the system of optimum paint consumption in the case of Sata models is not the most important. Such pistols are characterized by a high degree of ergonomic design, which can be supplemented with a wide range of nozzles.

It should also be borne in mind that the Sata gunsHVLP in this line are very sensitive to adjacent equipment. First of all, this concerns the installation of a compressor, which must correspond to a specific modification of the pistol in terms of pressure and power.

Walcom Genesi model

Competitive model in relation to the previousSpray gun, but also having its own characteristics. The user of this version of the nebulizer can count on minimum ink consumption, efficient transfer of about 70% of produced particles and durability of the structure. If the development of Sata was guided by the jewelry work with the creation of designs in the form of patterns, then this option is more likely to be useful for typical operations like painting a car body. In this case, HVLP spray guns from the Walcom Genesi family have one technological advantage. The design of the gun is complemented by a special air head with increased atomization of the composition. What does this mean in practice? The master will be able to work not only with the usual paint and varnish mixtures, but also effectively apply viscous masses. In addition, for water-soluble paints the manufacturer offers needles and nozzles of special design.

Model Bosch PFS 55

Unlike previous manufacturers, the companyBosch in this niche is not a premium brand, but a strong average. Modification PFS 55 is suitable for ordinary consumers who want to economically, but qualitatively improve the car or decorate one or another element of the facade without extra frills. According to the working qualities, the device is rather modest - the power of 280 W provides a flow rate of 110 g / min from a lightweight tank with a capacity of 0.6 liters. On the other hand, HVLP guns of this line are characterized by high ergonomics and reliability. The instrument weighs only 1.3 kg, so it is possible to plan and large-scale work arrangements, without thinking about the fatigue of the hand. As for the implementation of the HVLP system, this version provides a similar function thanks to the Spray Control system. As the manufacturer notes, this technology also helps to minimize the foggy effect when spraying paint.

Reviews about spray guns HVLP

Experienced car and paintwork workersThe studios note a noticeable savings in composition costs compared to traditional versions of the instrument. Together with the economy, the operator also receives the possibility of a more precise correction in terms of the direction of the jet. Although this option is more dependent on the configuration of the gun itself and the type of connection to the working head. But there are obvious drawbacks that the HVLP spray gun can disappoint. The reviews point to the fact that a reduction in the out-of-pocket paint consumption makes it quite logical to reverse the increase in the supply volume to the target surface. In other words, the abundance of the mixture is increased, which often leads to the formation of sags. Therefore, it is recommended to work with the HVLP system only for those who have sufficient experience in handling spray guns and are able to adjust jet parameters in a timely manner.

Conclusion

Inclusion of new technologies in a typical manualThe tool is always readily accepted by the consumer. Especially the masters who responsibly approach their work appreciate various ergonomic and functional additions. But, the development of designs and expansion of the option naturally leads to an increase in the value of the product. This rule also applies to the HVLP spray gun, the price of which in the middle segment is 6-8 thousand rubles. Devices from the premium segment are several times more expensive. For example, some modifications of the spray guns of Walcom can be purchased for 20-25 thousand. For comparison, models with the same characteristics, but without the HVLP system and in the standard technological version are available for 3-4 thousand.
