X-Boost Power Dial

Original and patented by Wagner, this technology allows the adjustment of the air pressure produced by the motor. In fact, it also means that your sprayer is three times more powerful as compared to the traditional ones.

What is the benefit of being able to adjust the air pressure?

Spraying at a higher air pressure result in faster coverage and smoother finish. On the other hand, if you spray at lower air pressure, the tendency is for the paint to drip.

This is because lower air pressure releases a more significant drop off materials. In effect, the finish created is rougher.

Note that the thicker the paint is, the more turbine power is required.

Two-step Trigger

As earlier mentioned and in connection to the X-Boost power dial feature, this machine also has a two-step trigger.

The first step, which you will activate after pulling to a particular point, is triggering the X-Boost turbine.

The second stage, when you pull even further, is enabling the material injection. This is the point where the sprayer releases the pain.


This paint sprayer is able to contain eight gallons per hour. Partnered with the X-Boost Power Dial, will give you the efficiency any user can ever dream of.

With its capacity and capability, you can finish any work at a shorter period of time. 

Adjustable Nozzle

Called the iSpray nozzle, this machine has two different vents which you can quickly adjust to adapt to your varying needs.

By simply rotating this machine's outlet, you can change the pattern and width of the arc, effectively turning the spray of the paint.

Use a narrow pattern if you are coating small areas, corners, or edges to control the coverage of the spray.

Meanwhile, use broader patterns on large surfaces.

Use the pattern adjustment rings to paint faster and change to quickly adapt to using latex paints, sealers, stains, and even oil-based materials.

Especially if you change the default settings, do not forget to test it before spraying. Do not trigger the gun while you are on the process of making adjustments. 

Advances Detail Finish Nozzle Technology

As mentioned earlier, this machine comes with two different nozzles. When using a traditional paint sprayer, you can regulate the finishing touch by rotating the nozzle.

This does not guarantee that you will get the type of finishing you desire.

To confidently create a more elegant finish, Wagner added another nozzle for you to use. This feature is particularly ideal for covering details and small projects such as figurines, chairs, edges of furniture, or paintings.

Note though that this nozzle is not very much ideal when you are using thick materials. It is best used with oil-based paints and stains.

Moreover, this machine is designed with a trademark feature of Wagner Lock-n-Go split gun design.

This one provides for quick nozzle change which will allow you to switch coatings easily. You can also quickly change paint colors because of this.

Material Flow

This machine is designed with a knob on the cap which allows you to control the flow of materials. By this, it means you can control the amount of paint you want to release.

This is mainly helpful especially if you are covering small, intricate areas like figures, edges, or corners.

Apart from precisely covering small areas, effectively, you are also able to reduce overspray with this feature.

How does it work? Just tighten the knob to shut the inner valve.

By doing this, you will reduce the flow of the paint. These are instances you do not want to use a lot of materials and result to overspray.

Moreover, the knob has a spring which keeps it from falling off.

Cleaning and Maintenance

After use, remove all excess paint back to the paint can.

Maintenance is pretty much straightforward and straightforward for this paint sprayer. As to the basics, all you have to do is to rinse the machine with water and then put it in the dry place.

Let the machine and tools dry and pull the trigger a couple of times to check possible clogging.

The kind of cleaning depends on the type of material use.

For instance, if you used latex and primer paint, then you have to make use of warm, soapy water to clean the machine thoroughly. Use mineral spirits for oil-based products.

Remember to do this while the machine is unplugged. Also, keep in mind not to get the electronic parts wet or it may result in short circuits.
