The main purpose of a tool such as an electric spray gun is the uniform and rapid coloring of the surface of the desired object with paint or varnish. It is a small device, which is convenient and easy to carry. Using an electric sprayer, you can easily cover the walls of the room, ceiling, interior doors or car parts. The main difference between an electric spray gun is that, when used, it is possible to achieve uniform application of the paint on the surface. As a result, you get a smooth coating, which can never be achieved using a roller or paint brush. And this means that in the process of repair you will be able to achieve results comparable to the work of professional painters.
Construction of the electric paint sprayer
The principle of operation of an electric spray gun is extremely simple. The paint from the glass under pressure passes through the nozzle and creates a uniform flow of particles. Spray guns, as a rule, have three adjustment systems:
- adjustment of air jet pressure at the outlet;
- Adjusting the needle, with which you can set the supply of the right amount of paint;
- Adjustment of the shape of the torch, with which you can adjust the desired shape of the paint spray.
There are several types of spray guns with different spray systems:
- reduced pressure (RP, Reduced Pressure);
- average pressure (MP, Middle Pressure);
- high pressure (HP, High Pressure);
- high transmission efficiency (HTE, High Transfer Efficiency);
- low volume and medium pressure (LVMP, Low Volume Middle Pressure);
- low volume and low pressure (LVLP, Low Volume Low Pressure);
- high volume, low pressure (HVLP, High Volume Low Pressure).
For different purposes, different types of spray guns are suitable. Electric spray gun for painting the house can be selected with the type of spraying LVLP. It is best for household use. The device with the HP spray system will cope with the painting very quickly, but the material consumption will be large. Tool type HVLP, by contrast, is very economical, but to ensure its operation will require a fairly powerful compressor. An electric spray gun of this type is suitable for painting cars.
How to choose an electric paint sprayer?

The main functional parts of the spray gun must be metal and as much as possible wear-resistant. Before buying, ask to disassemble the nozzle to check the quality of the needle.
- Check the gasket of the tool. During the operation of the household electric spray gun, sealing is of great importance. Therefore, connection pads made of poor-quality materials can quickly become unusable. In addition, the solvent, which is part of many paints, also adversely affects the longevity of the gaskets. Therefore, it is better if these parts are made of Teflon.
