Paint sprayer: description and selection of the device

A paint sprayer is a follower of a conventional brush or airbrush. The tool is designed to work with air and the use of liquid material. By its design, the product represents an enameled container into which a compressed air stream flows under pressure , and as a result, a jet is formed which is directed to the object to be painted.

The paint sprayer helps on production and at home for more than 100 years. It is most often used for painting coatings with quick-drying materials. This device has several advantages. Firstly, it allows processing objects of various shapes, producing color in hard-to-reach places. The simplicity of the design makes it undemanding to special paints, it can work with any liquids. Using a pulverizer increases productivity, because the work is done faster than with a roller or brush.

However, the paint sprayer has a number of significant drawbacks. During operation, a cloud appears consisting of solvent vapors, which increases the risk of fire. Because of this, the coloring matter is lost, and fine particles fall on foreign objects. Working with the nebulizer is harmful to health.

• Electric - work from the outlet and are the most economical for home use, they do not require the availability of additional devices.
• To the third kind can be attributed a spray gun with a manual drive. In this case, the pressure required for operation is created mechanically by means of a pump built into the reservoir.
