Learning a NEW Spray Gun SETUP!

3M regulator

Flexzilla air hose

[rikujkoivisto]

Set from gun pressure 29psi. Pressure always drops longer hose. Set wall pressure as require.. Do not be scared..! 😊

[MarcBchannel]

I run a 25' 3/8 hose from the wall regulator. Even with hf fittings and filter at the gun I drop about 10-15psi. I like to set the wall to around 60psi when spraying and adjust to what I need at the gun. If I set it at higher pressures for air tools it fluctuates the line pressure with the on/off cycles of my compressor, so it changes at the gun

[MarcBchannel]

I like a guage at the gun for repeatability but I try not to depend on one and learn to adjust accordingly by looking at what the material is doing. Different materials, guns, temperatures, and spray techniques call for different pressures. Just gotta play with it some. You want enough pressure to atomize to your liking. Sometimes some orange peel is needed to match/blend paint. Flatter coats call for more pressure and or less paint flow at the gun for a finer mist. Adjust your spraying speed to maintain a wet enough coat to flow out but not run. Use temperature appropriate reducers and hardeners

Tip: I like to place a 1 inch piece of tape over the gauge to reduce or eliminate over spray on it.

I bet at 29psi would atomize better so when the paint lands it is already speed out wider and level out better. Also if you don't already have them, you may swap to high flow fittings. They are the same outer diameter, but the Id is opened up for better air flow.

crank your pressure up on the wall and regulate at the gun.Plus all the regulators could be affecting your volume of air to the gun.

I'm going through the same thing just got a new air compressor 25 gallon 18.5 cfms I never used a regulator on my gun before.

Thank you. You could do an “Is it supposed to do that series.”

I saw your second video first and left a longer comment there.

FWIW, I run between 90-115psi in my lines, and if I have something (like my spray guns or blast cabinet) that needs less I use a regulator at the tool and regulate down. That way I'm the most likely to have the airflow that I need and lower the pressure to what I need at the gun. FWIW, with the small regulator on the gun I do see a pressure drop but nothing like you're seeing, I have >90psig in the lines, typically I'll see about 35-40 after the regulator and about a 10psi drop when I hit to trigger on the gun.

Yes to decals and giveaway. T Shirts.. your a good man .

[LTVoyager]

It appears you may not have high flow fittings on your hose. HVLP guns really need the high flow fittings and a 3/8” air hose.

[TD-ceru]

Help me out. I have a new hvlp gun that I have not used yet. It came with an air adjusting valve like what you have. I have the pressure regulator coming out of the compressor set at 80 psi. When I pull the trigger at the gun, the highest I can dial in the pressure is around 18 psi. Not only that, it acts like all or nothing. You an turn the adjusting valve four turns, but to get the highest psi. You can get that within the first revolution. The valve seems to be for volume of air. Why can't I get the pressure higher. Would a true pressure regulator at the gun be better or worthless.

Does a 75$ harbor freight spray gun work good with a 30gallon air compressor it’s like 4.5 Horsepower

[stevenhassell]

I don't see a water filter at the gun. What do you use.

[sb]

More pressure at the gun like 25 psi will give you less orange peel.

[NDB]

Mine 3m regulator is doing the exact same thing atm. What did you figure out. I’m using the 3m professional gun and it likes to run around 19 psi but to achieve that I have to have my regulator at the hose around 80psi and my gun sounds like it is screaming. I have a 50ft hose and high flow fittings. I have no idea what’s going on.

[jonathansmith]

Lvlp guns use the lower pressure like you have been used to spraying. At 26 to 29 psi with that hvlp gun you will save a lot of sanding before buffing to get rid of orange peel. You will get less orange peel using the higher pressures. Especially clear coat you could bump it to 30 to 32 and try it to get a flatter finish less orange peel.

[lowrides]

You got tooo many regulators goin on. Set it at 100 at the compressor then you can play with it at the gun. That middle one off the wall is choking your air supply. Just my opinion

[sinformant]

I got one of your decals from forever ago. Also like the paint kit giveaway idea

[jeffreyeaton]

HVLP is an air hog lol. I use a conventional cap for base and LVLP cap for my clear coat gun. My wall setting is 80 using all high flow fittings 25' air hose
