All You Need to Know about the Wagner AirCoat Spray Gun

Wagner AirCoat spray guns control the material application during painting with AirCoat paint sprayers.

In the following article we give you a complete overview of the structure and function of the Wagner AirCoat spray gun.

In addition, we have summarized all the information on the current available models and recommendations on accessories such as AirCoat nozzles, air caps and gun filters.

What is an Wagner AirCoat spray gun and how does it work?

The AirCoat spraying process is an air-assisted high pressure spraying system. The paint sprayer generates the pressure. The material is conveyed to the gun via a high pressure hose. In addition, compressed air is conveyed from a compressor via a second hose to the Wagner AirCoat spray gun and ensures a fine atomization of the spray material.

The AirCoat gun trigger is pressed to apply the spray material onto the surface. The spray jet can be adjusted with a set screw. The AirCoat air cap ensures optimum airflow and the AirCoat nozzle ensures the desired atomization of the paint or glaze. A filter in the gun protects the nozzle from contamination in the spray material and prevents blockages.

Detailed information on the AirCoat spraying process is summarized in the article AirCoat spraying At A Glance.

Which Wagner AirCoat paint spray guns are available?

The most common and current model among the AirCoat spray guns is the Wagner AC 4600. The gun fits well in the hand, has an ergonomic two-finger trigger and weighs 671 g. The maximum working pressure is 250 bar. The maximum air inlet pressure is 8 bar. For filtering the material, the classic Wagner gun filter is installed.

AirCoat nozzles for Wagner spray guns

AirCoat nozzles are located in the front part of the AirCoat spray gun and provide the atomization and optimum spray pattern when painted with AirCoat paint spray systems. That’s why it’s important to change worn nozzles regularly to create an optimal spray pattern and high quality surfaces.

Detailed information and help with the selection of the right nozzle, we have summarized for you in the article Wagner AirCoat nozzles.

Air caps for AirCoat pistols

AirCoat air caps are fitted to the fluid outlet of the gun along with the spray nozzle. There, the air cap ensures the correct air flow for distribution and even application of the spray material.

Thread on Wagner AirCoat spray guns

AirCoat spray guns have two connection threads. One thread for connecting the paint hose and a second thread for the air hose. For a long time it was common practice to use two different threads to avoid interchanging both hoses.

In this case, the paint connection was equipped with a M16x1.5 thread and the connection for the air hose with a smaller 1/4″ thread. 

Increasingly, AirCoat units are also supplied with a 1/4″ thread on the paint- and air hose. Make sure that the hoses are connected correctly. Otherwise paint or other materials can get into the air hose and cause it to stop functioning.

Spray lance for Wagner AirCoat spray gun 

For spray guns like the Wagner AC 4600, a spray lance in 30 cm length is also available. In this way, angled and difficult to access areas can be better coated.

Cleaning Wagner AirCoat spray guns 

After your work is done, the AirCoat gun should be rinsed and cleaned just like the sprayer. For this, the paint channel is rinsed and water or solvent is pumped through the gun. The filter should be removed and cleaned.

At regular intervals, the gun filter should be completely replaced. The nozzle should also be cleaned and protected against residual material buildup.

Tip 1: AirCoat guns as well as the filter housing of the gun can be cleaned well with suitable brushes. Order brushes directly here – order here

Tip 2: There are special cleaning needles for cleaning glued and clogged nozzles. Order cleaning needles here – order here
