What are spray guns?

Spray guns are equipment that can spray paint or varnish, using air pressure in order to apply paint or spread it on a surface. These guns can be used to paint on any type of surface or substrate, be it metal, wood, stone, clay (ceramics) and porcelain, plastic, glass and textile. For this reason, spray guns are fundamental tools for any type of house decor and DIY project, since they allow smooth finishing of any handcraft in an economical and efficient way. 

What are HVLP spray guns?

HVLP stands for High Volumen Low Pressure. These guns use a high volume of air to spray the paint, which for the most part goes to the surface to be painted, achieving a reduction of up to 75% of the paint loss. In addition, as less paint is dispersed in the air (the rebound effect is reduced), it could be said this system is healthier or more environmentally friendly.
So, a spray gun is definitely worth it.

How a spray gun works?

In just a few words, the spray of coating happens when the paint is applied to an object (the surface to be painted) through the compressed air gun. When the trigger is pressed, the paint mixes with the compressed air stream and is released in a fine spray. The consistency and pattern of paint can be defined and regulated by the correct use of the cup or tank where the paint is placed, and the nozzle that is chosen. Regardless of the type of technology used to paint, it is extremely important to frequently disassemble the nozzle of the spray gun to clean it and prevent it from becoming clogged with traces of dry paint.

What are the advantages of spray guns?

• Allow paint to be applied uniformly on the surface
• Allows different types of surface (even irregular or rough) to be painted efficiently
• Save time and production costs
• Detachable design achieves easier cleaning up
• There is good diversification for specific applications

What are the parts of a spray gun?

The sprayers are divided into these basic parts:

Jog Wheel Knob

Also known as shuttle wheels and jog dials, a universal wheel knob is a great add-on that offers an easy way to use with a single hand safely. This device is a useful control aid if you make a lot of turns in a sprayer. Jog wheel knob is used to adjust the spray length of our spray gun.

Flow Regulator

It is the piece that determined how much paint will come out through the nozzle and even allows to vary the shape of the paint jet. The very tight restriction of the flow regulator is not good practice. It has happened that the operators close the flow regulator a lot and with the force of the hand, exert a very large pressure on the trigger, which is transferred to the flow regulator, opening when the trigger is pulled. This force deforms the flow regulator and generates drips. It is better to adjust the flow from an external source such as the fluid regulator or restrictor and not the gun. In this way, the flow regulator will be only to activate and deactivate the painting flow.

The Nozzle

It is where the paint is expelled. Nozzle knob is used to adjust the round shape from vertical to horizontal. Many spray guns come equipped with several interchangeable nozzles, so the operator can choose the one that is appropriate according to the case. 3 spray nozzles of different diameters help aim more accurately without worrying of over spraying.
