Airless sprayers are high-performance equipment used for painting applications. The principle of operation is based on the crushing of the liquid when it passes through the nozzle. This method of staining reduces the consumption of materials when compared with the pneumatic method. This is due to the fact that the release of excess ink is reduced.
Airless sprayers are used in civil and industrial construction. They are intended for applying a huge number of paints and varnishes, among them:
- alkyd;
- acrylic;
- latex;
- epoxy;
- high viscosity formulations;
- putty.
Applying can be done by filling the tank with a fire retardant, anti-corrosion agent or textured compound. The exceptions are mixtures that contain among the ingredients cement, sand, stone flour and fillers in large volumes.
Varieties of devices according todrive type
Airless sprayers can be classified by drive type, they can be either electric or pneumatic. The latter variety is most popular in industry when it is necessary to carry out woodworking or painting large-sized products.
The advantage of such a drive is expressed in the absence of electrical elements, so you can work indoors, observing the rules of explosion and fire safety.
Description of electrically driven machines
Airless sprayers can be electrically powered for portability and small footprint. Such devices are used for large-scale construction and repair work, because the operator has the opportunity to connect additional spray guns. On sale you can find options for high-performance electric devices that are used in civil and industrial construction, for applying acrylic and latex paints, when performing interior and facade work, as well as, if necessary, applying putties, plasters, fire-resistant coatings and textured mixtures. The advantage of such a drive is its small size. The disadvantage is the inability to work in explosive and flammable environments.
Gasoline driven machines
Paint machinesairless spray can have a gasoline drive, it is characterized by high power, which reaches 4 liters. with. Such an engine has several advantages, the main of which is autonomy, because painting work can be carried out in a place where there is no way to connect to electricity.
The disadvantage of such painting machines is the need to use fuel and exhaust gases. This is true when it comes to work carried out indoors.
Description of Graco KA390
On sale you can find the Graco KA390 airless sprayer. This model is suitable for materials with medium viscosity such as enamels, antiseptics and varnishes. The equipment costs 65,000 rubles. The device is powered by an alternating current, which allows it to be used during repairs and painting work, where there is no main supply of compressed air.
The area of use is car services, furniture production and the manufacture of metal structures. This high pressure airless sprayer is capable of working with most paint materials, including:
- epoxy;
- water dispersion;
- alkyd;
- polyurethane.
The device does not require the need for complex maintenance, and in one day with its help you can do the work of several painters. After the purchase, the device is completely ready for work, it is supplemented with a high-pressure hose, the length of which is15 m. Included are:
- pistol;
- nozzle holder;
- spray nozzle;
- coarse intake filter.
Model specifications
If you are interested in high-pressure airless spray painting machines, then you should pay attention to the above model. Its maximum working pressure is 227 bar, the maximum nozzle size is 0.021 inches. In a minute, paint will be applied to the surface in a volume of 1.6 liters. The hose can be lifted to a height of up to 30 m. Equipment weighs 15 kg.
Description of WAGNER Project Pro spray gun 119
The Wagner airless sprayer 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 made in Germany and comes with wheels that provide mobility. This addition does not prevent the piston pump from moving around the site.
The machine has two support brackets that can be used to dismantle it for a compact size. The design is ergonomic and thoughtful, because it can be assembled and disassembled in a matter of seconds to be moved to any place by loading it into the trunk of a car. The body has a power switch and a valve,which is responsible for switching between painting and washing modes. On the opposite side is the pressure regulator. On top of the housing is a hole for lubricating the piston pump. There are clips on the sides of the frame for folding it.
Why else choose a Wagner model
An additional advantage of the Wagner painting machine model is the direct intake of paint material from the tank 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, which helps to extend the life and increase productivity.
The specialist will only have to choose the paintwork material that can be used:
- enamel;
- dispersion paint;
- impregnation for wood;
- varnish;
- light anti-corrosion materials.
Apply almost any solvent and water-based products with the machine.
Wagner atomizer specifications
The motor power of the above equipment is 720 W, 1.25 liters of paint will be applied to the surface per minute. 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 machine described above is designed for airless spraying of paints and varnishes, it is an equipment that is efficientand economy. You can use this unit by filling it with a material with a wide viscosity range.
The principle of operation is that the material is sucked out of the tank, and then fed under pressure into the gun and sprayed using a special nozzle. When working with these devices, fogging is minimal, while the treated surface is characterized by high quality of the layer and perfect smoothness.
