Best Paint Gun for Air Compressor Buyers Guide
Buying a paint gun for air compressors demands that you understand certain factors. The most expensive air compressor paint sprayer might turn out not to be the best choice for your painting activities. Therefore, you need not be price-driven. Instead, it would help if you considered the following factors.
Before purchasing an air compressor paint sprayer, you need to consider its durability. Find a sprayer that will last for the long haul. It doesn’t need to be expensive.
You’ll need to make sure that the sprayer is compatible with the paint you want to use. The sprayer will have a tremendous effect on the paint and vice versa. Small nozzles with a low pressure are best for thinner paints, while thicker paints need a bigger nozzle.
Ease of Maintenance
An air compressor paint sprayer that clogs easily will be complicated to use and clean. That can make painting pretty annoying and will make completing the job difficult. Therefore, you should choose the one that’s easy to clean, maintain, and doesn’t clog easily.
How to Set Up an Air Compressor for Spray Guns
When it comes to adding paint to the walls of your house, the garden fence, or the body’s surface, the setup of the air compressor for spray guns is necessary. A perfectly set up air compressor for a spray gun will make painting not only easier but perfect. However, setting it up is a rather big step, especially if you are not familiar with painting.
Spray painting guarantees a more controlled and smooth finish than using a roller or a brush. However, not all spray guns can guarantee optimal results because there are many substandard ones in the market. Getting an air compressor that matches the specifications of the spray paint gun will give you that incredible application.
There are three key things to consider when using an air compressor paint sprayer – the PSI, CFM, and the tank size.
Two types of spray gun use an air compressor – HVLP and LVLP spray guns. Both spray guns have low-pressure requirements. Therefore, they only need low pressure to operate. HVLP spray guns are better because they produce a high volume of air at low pressure. When painting, you need a high PSI to guarantee consistent delivery.
CFM (Cubic Feet per Minute) is the most significant factor to consider. CFM measures the air volume produced by the compressor per minute and the quantity of air the compressor can produce at a given Pounds per Square Inch. The CFM rating must be higher than the CFM requirements of your air spray gun. Otherwise, pressure drop and volume loss will occur.
The tank size is also vital. Spray guns require a consistent flow of air. Therefore, your compressor needs to have an ample storage to keep up with the supply.
Below is what you need and how to set up your spray paint gun with an air compressor.
- Suitable air compressor for the spray gun
- Safety gears, such as a respirator, goggles, and gloves
- Spray gun attachments
- Put your safety gears on.
- Attach the air spray gun to your air compressor via the hose.
- Make sure that your compressor delivers enough CFM.
- After confirming that the compressor delivers enough CFM, mix the solvent and paint to the correct ratios.
- Test the spray gun on a scrap to see that it’s producing a consistent paint flow. You can always adjust the knob on the side of the spray gun if you are not impressed with the paint flow.
- Once you are satisfied with the delivery, you can start applying paint to your chosen surface.
How to Use Spray Gun for Air Compressor
Spray guns are essential accessories for engaging the air compressors. They channel pressurized air from the tank to the target. The following step-by-step procedure will help you to use the spray gun for an air compressor better.
- Remember to wear your protective work outfit. This includes your gloves, respirators, overalls, and goggles. Wearing these is crucial to protecting your body from flying debris and other particulates.
- Prepare the surface by getting rid of any dust and excess debris.
- Next is to prepare the air compressor. Turn it on and wait for pressure to build up to the desired level. Some models allow you to set up the pressure. If you can’t do this, refer to their manuals to avoid making mistakes.
- After you are satisfied with the pressure levels, connect the air hose tightly to the sprayer. It has to be airtight to prevent air from escaping.
- Aim the nozzle at a piece of scrap or bucket and press the trigger. Keep pressing until all the specks of dust and debris are completely rid of.
- If no air is coming out of the nozzle, you might need to disassemble the parts to check the cause of the problem. You may need to refer to the manual again to check if you did things right.
- Reassemble once you have fixed the issue with the compressor and the spray gun.
- Mix the paint and the solvent at the proper ratio and test the spraying once again on a piece of scrap by pressing the trigger of the nozzle. If you are okay with the paint flow, you can direct the spraying to your desired target.
- When spraying, keep a comfortable distance between the surface and the sprayer to prevent the droplet from bouncing back and blocking the nozzle.
- After spraying, switch off the air compressor.
- Detach the parts and clear the room.
- Ensure that you clean the sprayer after use. You must do this to get rid of any dust particles or paint droplets around the nozzle.
- To clean, soak all the constituent parts individually in water and allow for some time for the dirt to loosen.
