Do you need an air regulator for spray gun?

It’s a good idea to have a regulator on or close to the gun, to mitigate any pressure drops in your system across air lines, and to be able to tune your gun’s spray pattern based on the type and viscosity of material you’re shooting. Regulators are relatively expensive, and they mount to the hose junction of the gun.

Why is it important to use a spray gun that has a pressure gauge?

When the nozzle orifice increases, droplet size usually increases. More spray and larger drops mean less efficient and effective coverage, and more wastage. A pressure gauge is very important in ensuring you get a predictable and regular spray result.

What is the purpose of an air supply regulator?

Air regulators are special valves that reduce supply pressure to the level required for efficient operation of downstream pneumatic equipment. A filter to protect the regulator’s internal passages from damage should always be installed upstream from it.

How much psi do I need to run a spray gun?

Setting the air pressure to about 28-29 PSI for clear will ensure you having great flow out. Most HVLP spray guns will use 10-14 scfm at 40 psi. This is volume of air pressure per cubic foot.

How does an air regulator works?

They consist of a spring actuated valve that is directly controlled by a diaphragm assembly. Energy or pressure from the flowing medium works to activate the diaphragm. The increasing downstream pressure acts on the diaphragm, which closes the valve plug by compressing the spring. This closes the valve.

What will you do if the spray gun is spitting?

Spray Gun Spitting If your paint gun is spitting or dripping paint, it is probably because the nozzle is not screwed on tightly. If you’ve checked your nozzle and find that it is screwed on tightly, you may need to purchase a new nozzle altogether. Spitting and dripping can be a sign of a worn out nozzle.

Why does my HVLP gun sputter?

If the packing where the needle goes into the gun is damaged or loose, it will sputter. Tighten the packing nut a bit and put a bit of Vaseline on the needle where it contacts the packing. A loose packing nut will cause sputtering. Another cause is a loose fluid nozzle.
