Airless Spray Painting

Airless spray devices are a high-performance equipment that is used for paint and varnish work. The principle of functioning is based on the crushing of the liquid when it passes through the nozzle. A similar coloring method reduces the consumption of materials, if compared with the pneumatic method. This is due to the fact that the release of excess paint is reduced.

Apparatuses of airless spraying are used in civil and industrial construction. They are designed to apply a huge amount of paint and varnish materials, among them:

• Alkyd;
• Acrylic;
• Latex;
• Epoxy;
• Highly viscous compositions;
• Putty.

The application can be carried out by filling the tank with a flame retardant coating, an anticorrosive agent or a textured composition. As an exception, there are mixtures that contain cement, sand, stone flour and fillers among the ingredients in a large volume.

Types of vehicles by drive type

Airless spraying devices can be classified by drive type, they can have an electric or pneumatic drive. The latter variety is most popular in the industry, when it is necessary to carry out work on woodworking or painting large-sized products.

The advantage of such a drive is expressed in the absence of electrical elements, therefore it is possible to work in closed rooms, observing the rules of explosion and fire safety.

Description of devices with electric drive

Airless spraying devices can have an electric drive, which provides mobility and insignificant dimensions of the device. Such devices are used for construction and repair works of large volume, because the operator has the opportunity to connect additional spray guns. On sale you can find variants of high-performance devices with electric drive, which are used in civil and industrial construction, for applying acrylic and latex paints, for interior and facade works, and also for the application of putty, plaster, fireproof coatings and textured mixtures. Advantage of this drive is a small size. The disadvantage is the inability to work in explosive and fire hazardous environments.

Apparatus with gasoline drive

Paint sprayers can have a gasoline drive, it has a high power, which reaches 4 liters. from. This engine has several advantages, as the main of which stands autonomy, because paintwork can be carried out in a place where there is no possibility to connect to electricity.

The disadvantage of such painting equipment is the need for fuel and exhaust gas removal. This is true when it comes to work in closed premises.

Description of the Graco KA390

On sale you can find the airless spray Graco KA390. This model is suitable for materials with medium viscosity as enamels, antiseptics and varnishes. The equipment costs 65 000 rubles. The device is powered from the AC mains, which makes it possible to use it when repairing and painting works, where there is no main supply of compressed air.

Areas of use are auto services, furniture production and fabrication of metal structures. This high-pressure airless spray machine is able to work with most paint materials, among them:

• Epoxy;
• Water dispersive;
• Alkyd;
• Polyurethane.

The device does not require the need for complex maintenance, and in one day with it you can perform the work of several painters. The device after the purchase is fully ready for use, it is supplemented by a high-pressure hose, the length of which is 15 m. The kit contains:

• pistol;
• Nozzle holder;
• A spray nozzle;
• Intake filter for coarse cleaning.

Technical characteristics of the model

If you are interested in high pressure airless spray painting machines, then you should pay attention to the above described model. Its maximum working pressure is 227 bar, the maximum nozzle size is 0.021 inches. A minute to the surface will be applied paint in a volume of 1.6 liters. The hose can be raised to a height of 30 m. Weigh equipment 15 kg.

WAGNER Project Pro 119 Painting System

Apparatus airless spray "Wagner" costs 52,900 rubles. This piston-type equipment is designed for different paints and can be used for painting and painting surfaces in a country house or apartment. The model is manufactured in Germany and has a set of wheels that provide mobility. This addition does not prevent the piston pump from moving around the site.

The device has two support brackets, with which you can disassemble it to give a compact size. The design is ergonomic and thought out, because it can be assembled and disassembled in a matter of seconds to move to any place by loading into the trunk of a car. On the case there is a power switch and a valve, which is responsible for switching between the coloring and washing modes. On the opposite side is the pressure regulator. At the top of the housing is a hole for lubricating the piston pump. On the sides of the frame there are clips for folding it.

Why else should I choose the model Wagner

An additional advantage of the "Wagner" painting device model is the direct withdrawal of paint from the container using a high-pressure hose. The material is fed from the original container, which facilitates the operation of the pump and does not load the motor, this contributes to the extension of the service life and increased productivity.

The specialist will only have to choose the paint material that can be made:

• enamel;
• Dispersion paint;
• Impregnation for wood;
• Varnish;
• Light anti-corrosion materials.

It is possible to apply almost any means on the basis of solvents and water using the unit.

Wagner Sprayer Specifications

The engine power of the above equipment is 720 W, per minute 1.25 L of paint will be applied to the surface. The maximum pressure is 200 bar. When working, it is necessary to remove the nozzle from the surface by 25 cm. The maximum length of the hose is 15 m. The length of the electrical cable is equivalent to 3 m. The nozzle has a diameter of 0.019 inches. The device weighs 18 kg.

Conclusion

The apparatus described above is designed for airless spraying of paint and varnish materials, it is an equipment that is characterized by efficiency and economy. Use this unit can be, filling it with a material with a wide range of viscosity.

The principle of operation is that the material is sucked from the container, and then under pressure is fed into the gun and sprayed with a special nozzle. At work of the given devices fogging is minimum, whereas the processed surface is characterized by high quality of a layer and ideal smoothness.
