Working at 100 PSI, the recommended compressor sizes are: Increase the size of your compressor in line with the size of your other equipment. Next, check the PSI and CFM of your sandblaster. You need a nozzle that’s durable enough to withstand the pressure from your chosen sandblaster. Check the guidelines for your sandblaster to make sure it’s compatible with your nozzle. You have many parts to consider when you’re sandblasting. If you’re working with a more precise project that requires a smaller blast pattern, a #4 nozzle measuring 3/16 inch, or a #5 1/16-inch nozzle will work better. These range in size from 3/8 inch to 1/2 inch. If you’re blasting large pieces of sheet metal, consider a #6, #7, or #8 model. If the same nozzle is being used with 140 PSI, the CFM must increase to 28.įor efficiency, you should choose the largest nozzle possible for your project. 2 nozzle at 100 PSI, your air compressor needs to provide a CFM of 20. You must also consider the necessary PSI for your project. The larger your nozzle, the more CFM you’ll need from your air compressor. Compressor Size and Nozzle SelectionĪs the size of your blast nozzle increases, so too does the necessary air volume and air reserve. Increasing the cabinet’s gun size can decrease your work time by over two-thirds. If you’re going for speed, bigger is better in this area. If you reduce your blasting pressure by half, your pressure cleaning project will take four times as long. If you work with a lower PSI, you’ll add a significant amount of time to your project. You should use a tank with a minimum of 100 PSI for optimum efficiency with any abrasive sandblasting project. Too little and it won’t be able to keep up with your job. To do so, your compressor needs to have the right air volume. The compressor doesn’t simply provide a single burst of air. The air and sand then exit the sandblasting gun together. When compressed air flows through the first hose, it creates pressure which pulls sand from a tank through the second hose.
Siphon Sandblasters: A siphon sandblaster features two hoses.Air and sand are pushed through the canister and into the gun together. Pressure Blasters: This sandblasting gun connects directly to a canister containing the sand.The pull of the air then draws sand through the hopper and out the barrel along with the air. The force of the compressed air firing through the gun opens the hopper. Gravity-Fed Sandblasters: These sandblasters feature a pressure gun with a hopper on top.Each one introduces sand to the air in a different way. The sandblaster fires sand out of an air-powered pressure gun at high velocity. Sandblasters clean rough surfaces by abrading them with sand. To properly size the compressor for your sandblasting project, it’s important to understand exactly how a sandblaster works. The size of your sandblaster and nozzle will determine the necessary size for your compressor. You must consider both numbers to make sure your compressor and sandblaster will work together. PSI (pounds per square inch): The pressure generated by the system.CFM (cubic feet per minute): The volume of air that the system can move in a minute.Compressor SizingĬompressors and sandblasters are sized based on: Use these tips and guidelines to help you make the best choice for your project. To get the best performance from your sandblaster, you need to select the right compressor for the job. A sandblaster can make a huge sanding job suddenly simple. Sandblasters are used to clean difficult substances like rust or paint from solid surfaces like metal.
