![]() ![]() As a result, many of these machines are better suited for small applications, such as removing paint from parts and pieces, rather than stripping an entire vehicle. These smaller machines also typically require less volume of air (liters per minute or cubic feet per minute) to operate. Generally speaking, small soda blasters with tank sizes under 40 kilo media capacity (90 pounds) have smaller delivery systems and use smaller nozzle sizes. In coming posts, I’ll discuss various soda blasting applications in detail, along with tips and ideas to help you with your cleaning project or business. Since most air compressors can easily provide that much pressure, you can begin to see why the cfm rating, or volume of air, is such an important factor in the soda blasting equation. ![]() For practical purposes, most soda blasting jobs require a final blasting pressure somewhere in the 25 to 100 psi range. Once that happens, your compressor will not be able to provide the necessary cfm, and you will experience a pressure drop, which may be too severe to allow you to do your job.įor example, if you are soda blasting paint off of a metal surface, and you set your blasting pressure at 90 psi, you may experience a pressure drop of 20 to 40 psi if your compressor’s cfm output can’t keep up with the cfm requirements of the nozzle size.Īll good soda blasters are equipped with an adjustable pressure regulator, which allows you to vary the final blasting pressure to suit the job you are doing. ![]() If your nozzle size is calling for more cfm than your compressor is capable of providing, you will drain your tank completely. What about tank size? A tank stores compressed air. You will not be able to use a large nozzle size if your compressor doesn’t put out the necessary cfm. Different soda blasters have different cfm requirements, depending on the size of the nozzle used. In general, the volume of air (cfm) will dictate the size of the nozzle you can use with your soda blaster. Pressure is expressed as psi (pounds per square inch) and volume is expressed as cfm (cubic feet per minute). Air compressors are rated by two factors: pressure and volume. Today, I want to discuss some of the basics about air compressors, and what you need to know to get the right setup for your soda blasting job or business.Īll soda blasters use an air compressor to provide compressed air to blast or shoot the soda blast media through the soda blaster. Once you understand how soda blasting works, it is much easier to appreciate why it is such an effective, and safe, cleaning method for many different types of jobs. In my first posting, I explained what soda blasting is, and what makes soda blasting such a unique cleaning process. Hi Everybody! This is my second blog posting about soda blasting, the environmentally friendly cleaning method that uses a form of baking soda (sodium bicarbonate) in place of other non-environmentally friendly, and health hazardous blasting medias like sand. ![]()
