How to setup the correct working pressure on a spray gun for best performance

Показать описание

In this instalment of GT Air Projects we show you how to correctly setup your spray gun for optimum performance, efficiency and atomisation. The extremely popular Burisch GTR500 LVLP Gravity Feed spray gun is used for this demonstration, in conjunction with the Fast Mover FMT3040 mini spray gun regulator. We’ll explain what all the adjustments do on the gun as well as explain the difference between static and working pressure and how to set it up correctly, accurately, every time.

I have bought 4 different regulators, convinced they were all defective, then I found this video and realized it was operator error. Thank you, as sad as it sounds, you've made my day 😄😁😃

I am so very glad I found this tutorial—this guy knows exactly how to dial in a spray gun. My first time out with a cheap LVLP—
AEROPRO Tools R500 LVLP Air Spray gun and I got through a gallon of Sherwin Williams Pro Industrial Pro-Cryl Universal Primer on an iron fence just in time to beat the rain that came overnight. No words can express my appreciation—I would have had to scrape rust a forth time, as it has rained every single time I have gotten the fence ready to prime. Thank you so much.

Watch over 30 videos about this subject. This one is the best. Thank you for sharing.

A perfectly scripted video, not one wasted word. Very helpful.

Great tutorial. This is one of very few that explains the difference between static and working/dynamic pressure at the inlet.

This is by far the most informative video on how to adjust the working pressure. Being a newbie, I didn't stumble this video until I have failed 4x to get my gun to work properly.

Thanks, as a very occasional Spray Painter this really helped me with my set up on this model gun.

It is important to note that this is just general recommendations. The actual air pressure you need may vary depending on the specific spray gun you are using, the type of paint, and the desired finish. It is always best to experiment with different air pressures to find the one that gives you the best results. In this case he is using the GTR500 which requires 29 working air pressure while the KBS Spray Gun is much different. The working air pressure for the KBS air spray is typically between 15 and 50 psi. The specific air pressure you need will depend on the type of paint you are using and the desired finish. For example, you will need a lower air pressure for a thicker paint like enamel, while you can use a higher air pressure for a thinner paint like latex.

This is the proper way to adjust a spray gun. Far too many users run the compressor output regulator too high and dial at the gun without realizing the problems it causes

Hugely helpful to someone who's never used a spray gun. Thank you!

Thank you Ewan Mcgregor :)
Needed that refresher, thank you.

Thank you for the detailed explanation! I had no idea how to use my new air gage at the gun so this video is very helpful!

Excellent video. The last few days I've been searching for a video that would explain exactly this. You detailed the steps in a way that was hugely helpful. Thank you
