If you have a tire machine that needs 130 psi, for example, while every other air tool needs only 90 psi, you should purchase an air compressor that can pressurize the air to 145 psi or more and use a pressure regulator to feed the air tool at 90 psi. As stated above, having the right air volume and pressure are key in choosing the right air compressor. While the best air compressor for a given body shop largely depends on the size of the business and the types of vehicles and operations it serves, asking yourself these common questions can make your search much simpler.
Rotary screw compressors and rotary vane compressors are now becoming more popular. Advocates for rotary vane compressors cite issues rotary screw compressors have with volume and efficiency due to the “Blow hole” and air leakage. Because rotary type compressors don’t need to be oversized for duty cycle, proponents say, and because they’re up to 20 percent more efficient than piston models, some shop owners are surprised to find that their 15-hp piston compressor can be replaced by a 10-hp rotary type.
Let’s look at our agenda, in part 1 we are going to cover 3 basic, but essential questions you need to ask in order to help properly size an air compressor, and then in part 2 we’ll cover 3 additional questions you need to ask in order to properly select an appropriate type of air compressor for your particular application, whether it be a piston or rotary screw air compressor. In order to correctly calculate the actual air requirements, or the ‘rate of flow’ for anticipated compressed air end-uses, it’s necessary to identify every pneumatic tool and equipment in your auto repair or auto body shop, and add up their SCFM requirements. Compressing air takes a considerable amount of energy, and the higher the pressure, the more energy is used, the more heat the air compressor generates, and the more wear-and-tear the air compressor bears.
Don’t let the size of this auto body air compressor fool you. To help you with that, we have prepared this buying guide that discusses in detail a few factors to consider before buying an air compressor for your auto body shop. Larger tanks compressors require the compressor to run less often because they can meet the pressure needed without being replenished for a longer period – While smaller tanks compressors will run more as air is used to refill the pressurized air tank.

What size air compressor do I need to do body work?
Vehicle service, repair and auto body shops typically rely on 5 to 30 HP air compressors with 80 to 240 gallon air receivers that power an automotive shop’s pneumatic tools and equipment.
What size air compressor do I need for automotive painting?
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 kind of air compressor do tire shops use?
Gas driven air compressors are the most popular type of air compressor on tire technician’s trucks. They are affordable, easy to source, and simple to operate.
What size air compressor do I need for blowing out sprinklers?
To properly blow out a sprinkler system, your air compressor needs to provide at least 20 cubic feet per minute. Most irrigation professionals recommend using at least 50 cubic feet per minute. Most air compressors will list their cubic feet per minute rating on the side of the tank.
Does tank size matter air compressor?
Tank size matters—sometimes The compressors we chose have tanks ranging from 1 to 6 gallons. A larger tank holds more air and will allow you to use more air before the pressure drops and the motor kicks on to refill the tank. That might let you avoid stopping work while the compressor refills the tank.
Will a 6-gallon air compressor fill a car tire?
Portable 3-gallon and 6-gallon compressors are typically better for larger tires. Many small compressors designed to be kept in vehicles are designed to provide a continuous supply of air so you won’t have to wait for the tank to refill at all.
How big of an air compressor do I need to run an impact wrench?
The average size air compressor you need is a 4-5 CFM @90 PSI for a ½” impact wrench. For instance, an impact wrench with a 1″ drive will need a 10 CFM @90 PSI, a ½” drive will need a 4 CFM @90 PSI, and ⅜” will need a 3 CFM @90 PSI.
Can you paint with a 20 gallon air compressor?
You should specify that your Air Compressor should carry 100 percent of the CFM the paint gun requires for small projects or only one panel at a time. Your spray needs to amount to 150-200% of the car’s weight in foam. I recommend using a 15-20 CFM air compressor with a 10 CFM paint gun for instance.
What size air compressor do I need to run a DA sander?
Great for metal and woodwork, dual sanders require 11 to 13 cfm at 90 psi.
Can you paint a car with a 6 gallon air compressor?
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.
What size air compressor Do I need to fill car tires?
To fill the tires of the car, you just have to run up to 32 PSI for most cars, or maybe 35 PSI for a cold day. A portable compressor 1 or 2 CFM, 90 PSI, must be used to fill the tires of the car. If you need to use a pneumatic exchange machine, then you will need 4 CFM or so.
What size air compressor Do I need to remove semi truck tires?
For domestic application, air compressor with 2 to 3 gallon tank size is suitable. But for heavy-duty applications like tire inflation, sanding and other that need continuous power and pressure, we recommend to go for 6 gallon tank size.
Will a 60 gallon air compressor run a tire machine?
Need to run tire machine. Any compressor that comes on at 145psi and stops at 175 psi and has a 60 gallon tank will work.
Is 150 psi air compressor good?
You’d only need maximums beyond 150 PSI for jobs such as automotive repairs and industrial purposes. Air compressors that do not reach a max of 90 PSI will struggle to power pneumatic tools. But they do a great job inflating sports equipment, bicycle tires, and car tires.4 days ago
How do I choose an air compressor?
When choosing an air compressor, consider the tools you want it to power. Determine which one requires the highest CFM at the highest PSI. Add 50% to the required CFM for a margin of safety, and look for a compressor that meets the requirement.
