While some air spray guns have a rating of lower than 10 CFM, we’d recommend your compressor CFM for spray painting is at least 12 CFM. For professionals, this figure may need to be higher – the important thing is you’ve checked your spray gun’s CFM requirements and chosen a compressor that exceeds that figure. 24 litre Air Compressor and Spray Gun Kit Secondly, our punchy 24 litre, 9.6 CFM compressor is fully equipped with a HVLP, gravity-fed professional spray gun, 10m rubber air hose, spray gun regulator with gauge, mini air filter and water trap and 2 quick couplers. 100 Litre Air Compressor & Spray Gun Kit Finally, our 100L, high-flow air compressor and spray gun kit will provide you with everything you need to quickly and efficiently complete any spray painting work you want to carry out.
In this article, we’ll talk about how you can choose the right air compressor to power your paint spray gun. It’s not the force of the air, CFM refers to the quantity of air the air compressor can produce at a certain pressure, say 90 PSI. The CFM is arguably the most important parameter you need to check for if you’re shopping for an air compressor for your spray painting project or business. After you determine the CFM of the spray gun, you need to make sure that the air compressor you choose produces more than the CFM of the spray gun.
If you have a spray gun or you’re looking to purchase one for a painting project at home or in the workshop, you may now be wondering what size air compressor you need to run your spray gun. The small Neiko spray painting gun requires 4.5 CFM, if the use was intermittent and only needed 25% of the time, then the spray gun only requires 1.25 CFM. Therefore, this compressor would be capable of providing that that CFM. However, if you are required to use the spray gun on a 50% duty cycle, the spray gun would require 2.25 CFM. The air compressor running at its recommended 50% duty cycle would not be able to provide the amount of CFM required by the spray gun. Well Jan, since you can get about 4 CFM of compressed air at 90 PSI for each horsepower of electric motor size on the compressor, your compressor should, theoretically, give you about 12 CFM at 90 PSI. However, if you are running your 3 HP compressor on a 120 volt supply line, then you sure are not getting that 12 CFM at 90 PSI, since, in my opinion, there isn’t enough power in a 120 volt line to power your compressor motor enough to give you that flow and pressure.
You might invest more When you select an air compressor for a car painting shop, where you need continuous airflow to spray gun, you should consider a bigger sized air compressor for heavy-duty performance. It would be best if you considered a 60-gallon air compressor, which one equipped a 5HP motor and capable of producing a minimum of 10CFM. If you are a hobbyist painter and involve in weekend painting at your home garage, a 6-10 CFM air delivering capable air compressor is a perfect fit to handle your criteria. The benefit of having a big-sized air compressor unit for performing nailing tasks, driving auto repair air tools is that it may use auto painting and furniture painting jobs at the home garage.
That’s why we’ve tested, measured and compared over 30 air compressors for spray painting. Overall, we think this is the best spray painting air compressor for the money available this year. The California Air Tools 10020C is our choice as the best air compressor for spray painting, with the PORTER-CABLE C2002 taking the spot as “Best air compressor for spray painting for the money”.
HVLP is environment friendly: Of course, masks should be worn as a precaution but with an HVLP spray gun, the sprayer will be exposed to less overspray dangerous for the health. Our light weigth FPro and M22 spray gun ranges offer great precision : the HVLP solution can be used for some very sensitive touch up coating spray work. In order to be compliant with the 0.7 bar/10 psi at the aircap, a Fpro HVLP gun requires more airflow in order to release the paint into fine particules as the air pressure is decreased compared to a conventional Airspray gun, while keeping ideal spray patterns.
This article will cover the best types of air compressors for painting & painting cars, what your air compressor will require to be able to paint cars, and things to consider when choosing an air compressor for painting. Number 1 Factor in Choosing an Air Compressor for Painting – Air Compressor CFM. Spraying paint with an air spray gun requires a large volume of air being injected into the paint which creates atomization or break up of paint. So if you will be using your air compressor for painting or painting cars, you will want to consider a 2 stage compressor with atleast 5 Horse power to properly provide air to your spray gun.
what air compressor for spray gun Related Question:
What size air compressor do I need for a spray gun?
For small projects or single panels, your Air Compressor should be rated at 100% of the CFM required by your paint gun. If you’re spraying a whole car, you’ll want 150-200%. For example: A 15-20 CFM air compressor is a good match for a 10 CFM paint gun.
Can you use regular air compressor for a paint sprayer?
Using an air compressor and a paint sprayer can help you cover more space at one time and can help you make sure that you get an even coat of paint on your surface. Follow the tips below for using a paint sprayer connected to an air compressor to help you achieve a professional paint job.
Can a 6 gallon air compressor run a paint gun?
What Size Air Compressor Do I Need To Run A Paint Sprayer? Because of this, you cannot use a 6 gallon air compressor to spray paint. It is necessary to have a compressor with a large tank, preferably 50 gallons or more, in order to be able to spray paint with a spray gun.
How much psi should a spray gun have?
How Much Air Pressure Does A Paint Gun Need? Most people say that 10-15 psi when the trigger is pulled for a base coat is the ideal setting for their guns. When spraying base coat and clear coat with low volume low pressure spray guns, I spray at about 17 psi.
Can you paint a car with a 20 gallon air compressor?
Additionally, a small air compressor will fail in painting a car in whole, because it must fit under the paint surface. A smaller air compressor will fit into car cases, bumper covers, and other vehicle parts, like motorcycles. This means running a 20- to 30-gallon air compressor.
Will a 10 gallon air compressor run a paint gun?
If you are using an Air Compressor for a small project or single panel, make sure it is rated at 100% of the CFM. A 150-200% spray rate is recommended for a whole car. An air compressor with a capacity of 15-20 CFM is a good match for a paint gun with a capacity of 10 CFM.
How many CFM do I need for a paint gun?
For a quality HVLP Spray Gun you can often need up to 20 CFM of air. If you are using a Conventional Spray Gun you may not need as much air as HVLP requires a High Volume of air (HV) especially compared to conventional spray guns, but a conventional spray gun can still use 10 – 15 CFM.
What type of air compressor do I need?
The best formula for calculating the right sized home air compressor is to add up the CFM requirement for all the tools you intend to use as well as identify the peak PSI each one needs. This gives you the upper limit of what tank size in gallons, capacity in CFM and pressure in PSI you require.
Do you need an air compressor for a spray gun?
The most common air paint spray guns use a “high volume, low pressure” (HVLP) delivery mechanism, so you need a spray paint compressor that delivers the necessary pressure and volume of air to achieve a perfect paint flow.
Do you need an air compressor for spraying?
To be safe usually around 100 CFM to 130 CFM is good to have available for an Air driven Airless Paint sprayer (electric and gas airless sprayers do not need a compressor). If you use a compressor that is small you have to make sure you properly mach your spray equipment so that it doesn’t require a lot of air.
What is 2 stage air compressor?
In a single stage compressor, the air is compressed once; in a two stage compressor, the air is compressed twice for double the pressure. By increasing the number of cylinder stages and pressure, these machines work more effectively with a faster recovery time, and can handle more tools at once.
What size air compressor do I need to run a HVLP spray gun?
HVLP guns require plenty of air, so you need to have a larger capacity compressor higher than those used for diy home works. In order to spray the full range of finishing products, however, you need at least a 21⁄2 to 3 HP compressor with a 75 liters (20 gallons) tank.
Is a 3 gallon air compressor good for painting?
It is recommended that you rate the pressure in your Air Compressor to 100% since a smaller project or single panel can require more pressure. For spraying purposes, 150 to 200% will work. In the case of a paint gun with a 10 CFM airflow, a 15-30 CFM air compressor would work quite well.
How big of a compressor do I need to paint?
Look for a minimum of 15 psi, with some applications, such as clear coat, better-suited to 20 or 25 psi. Horsepower: For auto painting, a 10hp compressor will typically suffice. However, higher horsepower compressors may operate more efficiently, and can be used for other tasks.
What PSI should I use to spray primer?
A general rule of thumb is: Heavy-bodied primers and primer surfacers work best when you use a nozzle size of 1.7 to 2.2. Basecoats should be sprayed with a 1.4 to 1.6 nozzle. Clearcoats should be sprayed with a 1.3 to 1.7 nozzle.
