How to choose a gun for home use ?

How does the gun?

principle of operation of this instrument is to apply the composition of the air jet.A jet of compressed air which passes through the nozzle divides the material into fine particles and spraying creates.From the nozzle diameter, that is, from its passageway depends form the coating material, its viscosity, etc.

Think about how to choose the best airbrush to paint sprayed qualitative.In this article we have tried to carry out the separation by type of product and describe parameters that should pay attention, already standing at the counter.

How to choose a gun - there is something to compare

To date, there are four spray devices varieties to choose from which can affect our comparison spray guns:

• Spray with low pressure consume much more air, and this requirespowerful compressor.In addition, use a hose with a diameter smaller than the hole in the handle.Work at a distance of 15-25 cm from the surface.Variant
• device with a high pressure is applied to the application of enamels, varnishes and coatings base.It causes qualitative and spray materials.It operates at high pressure and consumes a small amount of air.The distance to the surface to be coated should be 30-40 cm.
• Universal Spray combines the properties of the previous two.Note that the low pressure transfer device to the product surface composition is 20-30% efficient, which means that using such a device, get good ink savings therefore possible to choose the spray gun in this embodiment.
• Model LVLP - the best type of sprayer.It consumes little air at low pressure during operation.It also has the highest percentage of ink transfer.

Select the tool for yourself - what to look for?

To make the right choice of gun, you need to pay attention to the following points:

1. Packaging and appearance.Global manufacturers produce their products in a plastic case, which can also be optional additional accessories.The body of equipment should be made of aluminum coated with nickel, which protects against corrosion gun.

In addition, special attention should be paid to inspection holes on the nozzle cover.Quality made of stainless steel, aluminum and brass.It is better to carry out a test spray guns, that is to press the trigger for determining the accuracy of the needle in the nozzle.

2. Seals.It is critical that all connections were sealed well, especially with low operating pressure.Furthermore, most paints are composed of solvents, which may spoil the gasket.The most reliable seals are PTFE, but unfortunately, they are often used in expensive professional devices.Therefore, before you select a spray gun, this item should be given due attention.

3. It is also necessary to determine the location of a barrel of paint.It is at the bottom and top.The essential difference is not just for themselves to vote, a gun is better and easier to use.Barrels made of metal and nylon.

first advantage is that it is easier to clean, but it is not clear.But the advantage of the plastic barrel is that it can be seen material consumption.Sprays with bottom edging have to be held vertically to the tube got up, rather than the air.It is very important before you pick up a gun, follow the above tips, then you will get a high quality machine for the application of paint.
