Do I Need A Regulator for A Paint Gun?

best air regulator for hvlp spray gun

It is worth it to use any gun regulator for a paint gun. Paint gun regulators will help mitigate any pressure that sits across the airlines. It will be able to tune your gun’s spray pattern based on the types and viscosity of the material. 

On the other hand, most HVLP guns will require the lowest pressure than other gun tools. Although the regulator is expensive, they work to lessen the aggressive pressure and junctions inside the gun. The paint gun regulator is also helping to even out your trigger pressure. 

Regulator Works to Even The Pressure Flow

While you’re using any regulator inside the gun pressure, you will be able to see a tiny hole in the barrel. Its gas regulator sits and allows your pressure gun to operate the action. An adjustable paint gun allows it to run enough gas to prevent the overflow or spread of aggressive paints. 

Enhance Painting Experience

The second most crucial factor you are getting from here is a quick output. The regulator holds the pressure inside the machine. It will enhance the painting experience. For this reason, a user doesn’t need to be so experienced in this regard. You won’t need to balance the pressure gun before shooting over the wall.

Balanced Your Trigger Point

It is a common mistake for beginners; they usually fail to balance the shooting pressure. As a result, one cannot balance the trigger point of the gun. Some experts think that the regulator works as a gun-loader to adequately shoot it at the targeted point. 

Reducing Air Consumption

While your gun will produce excessive paint, which you won’t need, it will be a more significant expenditure to buy paint frequently. The regulator will lessen this and also save some cash of yours. Because this regulator will fix the spring tension of your paint gun, it will help to decrease air consumption.

Good handling of any spray gun is enough to give you satisfactory outputs. Some products have fewer comfort zones, which don’t allow you to work suitably. So check these factors whenever you shop for any paint gun regulator. 

Good for Multiple Usages

It is crucial, and we think tools like paint gun regulators and users shouldn’t skip this criterion, especially if you’re a professional painter or home interior designer. A paint gun can be used for many reasons. You might need it for woodworking, re-painting the home, for official projects, and also you may need it for furniture varnishing.

Price often lets you push over any product. Suppose you may choose any regulator that meets all your demands. But when it comes to the price, you may not pick it for the shortest. That’s why we don’t tell you to increase your budget. But try to plan it first to match your pocket to your desired product price equally.

How Do You Adjust PSI on A Spray Gun?

how to adjust spray gun

Any spray gun’s right and adequate psi is about 15-20 psi. Moreover, you need to be strategic to adjust it on a spray gun. Keep in mind that once you’re successful, adjust it on a spray gun. You are all set to get the determined psi that one expected. To do it properly, follow the below steps carefully. 

Step 1- Adjust The Spray Gun Regulator

Start by adjusting the spray gun regulator. To adjust it, turn on the regulator endpoints. Set up the regulator to the paint gun. It’s well to mention that most spray guns have three basic control types. This will allow you to adjust perfectly to get optimum performances.

These include fluid adjustment, fan control, and air micrometer. You must start with the last two controls, named fan control and fluid control knob. Adjust it to the regulator. Make sure all the internal air pressure of the paint gun will be adequately exhausted. 

Step 2- Set Up The Fluid Control Knob with The Regulator

In the second step, you will adjust or set up the fluid control knob to the regulator. Be aware that the paint or fluid will not be decreased while you trigger the gun. Check twice that the paint holder cup will adjust with the regulator properly. Tightened all the knobs and screws with the help of a wrench. Now go for the next steps. 

Step 3- Check out The Fluid Consistently by Shoot It Frequently

Once you’re sure enough, you adjust the regulator with the spray gun. Give a trial to ensure that the psi is enough to paint any objects from a minimum distance. Shoot with the gun frequently anywhere and check the psi number. If you need to increase it, keep pressurizing the trigger point of the gun to increase the psi level. 


1. What PSI Should A HVLP Gun Be Set at?

PSI will recognize the fact of the paint gun as it is directly interlinked with the spraying power. The expert will recommend choosing the PSI between 25-30 whenever you’re triggering the pull. On the other hand, HVLP guns come with some paint tech sheets that refer to a painting air pressure around 8-10.

Besides this, you shouldn’t set up the spray gun on those paint tech sheets. This is because it is only suitable for the air cap pressure where the paint liquor comes off.

2. How Much PSI Does A Paint Gun Need?

A paint gun usually needs 10-15 air pressure. As we have already mentioned, air pressure is the main to drive the paint gun properly. This pressure keeps the trigger swiveling, sets it to spray on, and sticks on to the targeted point. 

However, the psi of any paint gun may vary depending on materials and other facts. For this reason, you may find 20-25 psi for the clear coats. And if you require any auto painting, it may increase up to 10 hp or above. 

3. What PSI Do You Spray on A Clear Coat?

The clear coat is a heavy-duty coating material that is easily dissolved in water. These coatings are generally used for advocating cross-linking mechanisms. So when it comes to painting over those materials, you need to trigger the gun around 26-29 psi. 

It is the base of the explicit coat materials, and it will help let airflow through the gun’s tip. You must load the gun with maximum psi to get a smooth finish. 


Finally, we want to tell you that it may be challenging to find a suitable regulator. But the task may be more facile for you once you finish reading out the entire article at a glance. 

More importantly, if you don’t have time for this. Then we highly suggest you get the Primefit CR1401G Replacement Air Regulator. This will come with a compact size, functions, and durability. Above all, Prime Fit has good ratings and positive reviews from its customers.
