Here, we\u2019ll explain why this equipment is so vital in your automotive shop, before taking you through all the necessary considerations when deciding which type to go for.<\/p>\n
Air compressors are an essential tool to help bodywork painting professionals achieve a strong and continuous flow of paint throughout their paint job.<\/p>\n
But first, there are a few commonly mentioned technical terms to go through concerning the functions of air compressors. We\u2019ll explain these below to help you understand what we mean by each one.<\/p>\n
The next thing to understand is that there are multiple types of air compressors available.<\/p>\n
1-stage compressors only deliver 1CFM\/hp, while 2-stage compressors provide around 4 CFM\/hp. The most popular options that automotive paintwork professionals go for are rotary screw and piston compressors.<\/p>\n
The reason that these are some of the most popular options in automotive shops is that they\u2019re often quieter, more efficient and can handle the high volume of air required by paint sprayers.<\/p>\n
Many auto repair professionals will also opt for a rotary screw compressor over a piston compressor because of its three-stage motor offering a better compression performance. Meanwhile, piston compressors run from a single-piston motor which can vibrate more and is usually louder. They also offer a less powerful compression, which isn\u2019t ideal for painting large areas or completing jobs that might take longer.<\/p>\n
So, the next thing to consider is the required features you want your air compressor to deliver on. Below, we\u2019ll guide you through the main considerations to ponder over when you\u2019re deciding on which air compressor to purchase for your automotive shop.<\/p>\n
The tank size is an important consideration to think about because this will affect the efficiency of your equipment and the painting process.<\/p>\n
A bigger tank will allow for continuous use of your air sprayer over a longer period without the need for a refill. However, a smaller tank will slow down the spray-painting process since it\u2019s likely you\u2019ll need to refill the tank more often when you run out of compressed air.<\/p>\n
Cost is an important factor to consider when purchasing any piece of equipment for your automotive shop. It\u2019s necessary to think about your budget and your needs in combination when considering the price of your air compressor.<\/p>\n
For example, if painting isn\u2019t a major service offered by your shop and you\u2019re working with a smaller budget, it might be best to go for a portable or piston air compressor. While these won\u2019t offer the same efficiency and performance as a 2-stage compressor such as a rotary screw, they will still allow you to achieve an evenly distributed paint job.<\/p>\n
However, if you\u2019re willing to spend a bit more and often need to use a spray painting gun, we\u2019d recommend choosing a 2-stage air compressor. These are often more expensive but are definitely worth the investment.<\/p>\n
The flow pressure needed depends on the task at hand. For example, a lower flow pressure is often enough for painting a smaller panel with a good time gap between coats. This is because it can provide just enough CFM to paint the area before the equipment needs to build back its pressure for the next job.<\/p>\n
However, a higher FAD or flow pressure is needed in most cases for automotive professionals because it can offer more CFM. Therefore, the pressure can flow for longer and allow you to complete a variety of painting jobs.<\/p>\n
To achieve the best finish, it\u2019s recommended to choose a compressor offering up to 20 CFM. Since most auto repair professionals work with high-quality low-volume (HVLP) air guns, this high volume of air in relation to cubic feet will aid with achieving the highest quality finish.<\/p>\n
It\u2019s usually ideal for CFM to be between 10 and 15 if possible.<\/p>\n
The minimum size air compressor you need will depend on the size of the job at hand. However, it\u2019s recommended that you choose a tank size over 50 gallons if you intend to use it for painting a car.<\/p>\n
