You’ll also want good ventilation so that the air heated up by the compressor can move freely out of the structure, so the compressor stays cool and prevents overheating. This allows you to move around the air compressor if you need to troubleshoot it, provide maintenance or similar issues. No matter where you house your new air compressor, however, you’ll want to make sure there’s at least 36″ of space on each side around it. Because of the amount of noise that it can produce, many businesses choose to locate the compressor in a separate room or structure with compressed air piping run to the shop. Once you’ve selected an air compressor, consider where you’re going to place it in or near your shop. Another aspect to consider is an air filter in line, especially for the painting process, as moisture or oil in your paint can cause flaws in the final work. ![]() Take the time to determine both figures, then if you choose to go with a piston compressor, consider that you’ll probably need to increase the tank capacity by 40-50% to prevent the compressor from running longer than it should. By comparison, your spray guns may only require between 30-60 PSI, but at a much longer volume as they run for extended periods of time. How much air pressure and air volume do your tools need? Some tools, such as truck jacks, will require pressures up to 165 PSI, but only for a short period of time. This means that rotary screw compressors can run all the time without causing problems to your overall system longevity. By comparison, a rotary screw compressor can be smaller in size, as its duty cycle is closer to 100%, if not at 100%. Most piston compressor systems are designed to have a 60-70% duty cycle, which means you’ll need to intentionally “oversize” your system to prevent the compressor from burning out over time. Should you go with a piston compressor or a rotary screw compressor for your operation? The first thing to bear in mind is the duty cycle. Once you’ve estimated your total maximum air volume and pressure needed at a time, make sure to add an in an extra margin to allow for future growth of your business or for extreme circumstances. How many spray guns will you be running at a time, and how much air volume and air pressure will they need to operate successfully? Spray painting will likely take up the bulk of your size needs, but you’ll still need to calculate for other air tools, including impact wrenches, tire inflators, grinders and sanders. While it’s easy to assume that you need a certain gallon air compressor to keep up with your needs, you should go beyond that point when calculating the size of air compressor for your auto body shop. What to Consider when Purchasing an Air Compressor ![]() In fact, the number of air tools used in an auto body shop can be overwhelming, which is why you’ll want to go beyond a simple portable air compressor and look into a quality industrial or commercial air compressor that can keep up with your shop’s demands. There are a ton of air tool applications, including an impact wrench for loosening lug nuts on tires, a spray gun for painting vehicles once repairs have been made, digital tire inflator tools for bringing tires back up to pressure, and grinders, ratchets, sanders, and more. Let’s start by looking at all the things you can use an air compressor for in a body shop. Why Do You Need an Air Compressor in a Body Shop? In this post, we’ll explain what you need the air compressor for in your body shop, what you need to consider when purchasing an industrial air compressor, and which air compressor is right for your needs. But what tools will you need to run from your air tank? What do you need to take into consideration in your compressed air system? Are you a small shop that can run on an air hose or two from your main tank without lowering air pressure or air volume too much, like a regular automotive shop with a digital tire inflator or a home garage running an impact wrench? Or will you be painting car after car with a spray gun?įinding the best air compressor for body shop work can seem like a difficult process, but it doesn’t have to be. Whether you’re taking over a body shop business with an existing air compressor that doesn’t seem to be keeping up enough or looking to purchase your first compressed air tool system and need to know the basics, there’s no doubt that auto body work requires a particular set of equipment and technology that go beyond that of normal pneumatic tools.
