Although it is only a small piece of its sprayer, the nozzle is of great importance.

We will explain briefly and concisely why this is so.

What's a nozzle for?

Airless sprayers push high-pressure paint (up to 350 bars) through the small nozzle hole. the nozzle indicates to the pump the intensity with which you should work to maintain the necessary pressure. the nozzle ensures that the paint is atomic according to a certain width of the fan and flow: an effect similar to placing the thumb at the end of a garden hose.

Why is it so important to choose the nozzle well?

A suitable nozzle ensures a lower overburden and therefore a better control and finish. this way, not only will less paint be used, but it will take less time to carry out the task.

A suitable nozzle:

• increases its performance

• improves the quality of your work

• keeps your budget down

Why are there so many nozzles and so many different sizes in fat?

A simple comparison would be the choice of the right drill for a drill.

There are brushes specifically designed for wood, while others are for metal or concrete. Furthermore, all the drills are available in several different sizes.

When using the incorrect drill on the wrong surface, you will not get the desired results. something that also applies to airless nozzles.

Not all nozzles are the same. and there is a good reason for it. find out below how to differentiate some of the other nozzles

Example. PAA517.

• The color informs the application for which the nozzle can be used

There are four types of nozzles for the rac x nozzles, which is used the blue head rac x 246215 , the rac v nozzle with the orange holder 243161 with thread 7/8 or 243263 with thread 11/16 ( wagner guns, wiwa., . ) and xhd grey nozzles with xhd portaboquilla gray, each specific one.

Each type of nozzle has assigned its own color, which allows to distinguish them easily.

Fflp and lp (green) .. guarantees the best possible low-pressure finish for high-end applications and wall paints. Interior painting and residential projects

(blue ) For wall painting, it is compatible with paint spraying in general. Interior and exterior painting work in homes and indotrial or commercial projects

Hda ( brown )For diluted lighting and less fluid products, intumescent type, masks. Interior and outdoor painting work with airless and high-production applications

LL5 (yellow) for road signs Signage of parking spaces, roads, warehouse floors, pedestrians and sports courts

Rac v (black ) , universal nozzle GracoCompatible for all uses.

Xhd (grey) 500 bars nozzle, for indotria, available all steps.

• The first number indicates the width of the nozzle fan ( example nozzle 517 )

The first digit ( 5 ) represents the width of the spraying (the width of the fan) and corresponds to the angle of spraying.

If the number is "5", then the spraying is done at an angle of 50°. By multiplying the number by five, you get the width of the fan when the gun stays 30 cm away from the surface. 5 × 5 = 25 cm ( fan width)

• The last two numbers indicate the spraying hole of the nozzle

The last two digits of the nozzle ( 17 ) designate the size of the spray hole in the form of a thousandths of inch. The higher the number, the higher the flow will allow to spray.

Thus, for example, a nozzle "517" admits a flow greater than a nozzle "515". «17» refers to a hole of 0.017 in (0.43 mm)

The choice of the right nozzle is realized in three steps.In the first place, it is necessary to determine what application the nozzle will be used (i.e. what product is to be sprayed) and then the width of the fan and the flow required

Step 1

What app will you use the nozzle?

Each nozzle has been developed for a specific application. High-end products (such as dyes or varnishes) need a nozzle with a smaller hole. On the contrary, the heavier products (such as plastic paint) require a larger hole. depending on the color of the nozzle, you will know immediately what is best suited to your application.

Step 2

What is the width of the desired fan?

The width of the fan is determined by the angle when it is sprayed 30 cm away from the surface. The wider the distribution of spraying, the faster the large surfaces will be painted, although the consumption of paint will also be greater. with a smaller distribution, it works slower, but the consumption of paint is lower and the control increases. calculate the width of the fan you want and divide that figure between 5. the obtained value will tell you which must be the first number of your nozzle.

For example, if the width of the fan is 25 cm, then the first digit of the figure should be 5 (= 5 × 5). the number 5 corresponds to a spray angle of 50°. on the other hand, if you want a width of 35 cm, the first digit should be a 7 (7 × 5 = 35). the angle in this case is 70°.

Step 3

What is the maximum flow rate of the sprayer?

The size of the nozzle hole determines the amount of paint that this sprays. the maximum flow of the sprayer must always be greater than that of the nozzle. the actual flow depends on the pressure of spraying and the type of paint used: the higher pressures produce a higher flow, while the heaviest types of paint reduce it.

In the table below, choose the flow of your nozzle and check if it is appropriate for your equipment. never use a larger nozzle size than your computer can process. The sprayer must be able to pump with a minimum flow rate.

In the following list will help you choose the right nozzle for each specific application and product.

From the general information included now you can choose the nozzle that best suits your application. However, here are some tricks and tips more.

Garlic of the right nozzle

When testing different nozzles, you will acquire the necessary experience to easily decide what is best for your application.

Nipple sotitution in due time

If we take up the comparison between the nozzles and the drillholes, it will also be easy to understand how the wear of the nozzles can affect your work. Have you ever tried drilling concrete with a worn-out drill? If yes, you will know that it takes much longer to drill a hole, that the effort to achieve it is greater and that the result seems less professional.

This same happens if you continue to spray with a worn-out nozzle. Furthermore, if you use a worn-out nozzle, there are quite a chance that it will exceed the maximum flow of the sprayer.

In short, a worn-out nozzle will cost you more than a new
