Sizing an air compressor for sandblasters can sometimes feel like a daunting task. However, with the right knowledge and guidance, it can be a straightforward process. This article aims to provide you with the necessary information to help you size the right air compressor for your sandblasting project.
Key Considerations for Sizing an Air Compressor
When sizing an air compressor for sandblasters, there are a few key questions you should ask your supplier:
- What size nozzle is being used?
- Does the nozzle wear?
- What size air compressor do you recommend?
- For new systems, know what power supply is available
Understanding the cubic feet per minute (CFM) required per nozzle and the available power supply can help you size the right compressor. Power supplies range from 115/1/60, 230/1/60, 230/3/60, to 460/3/60. Remember, single-phase limits the size of your air compressor, limiting you to a maximum of a single, 7.5 horsepower compressor or multiple units.
Tips for Sizing Air Compressors for Sandblasters
Here are a few tips when sizing air compressors for sandblasters:
- 15-17 CFM = 5 horsepower air compressor
- 18-25 CFM = 7.5 horsepower air compressor
- 26-37 CFM = 10 horsepower air compressor
- 38-60 CFM = 15 horsepower air compressor
- 60-80 CFM = 20 horsepower air compressor
- 80-110 CFM = 25 horsepower air compressor
- 110-125 CFM = 30 horsepower air compressor
- 125-180 CFM = 40 horsepower air compressor
It is recommended to size the air compressor 20% over the demand or requirement.
Choosing the Right Type of Air Compressor
If you plan on operating the sandblaster on continuous duty, it is recommended to install a rotary screw compressor since they are rated for 100% duty. If you plan on running the sandblaster at a lower duty cycle, a two-stage air compressor would work just fine.
Conclusion
Sizing an air compressor for sandblasters doesn’t have to be a headache. With the right information and guidance, you can easily select the right compressor for your needs. If you have any lingering questions, feel free to contact the team of experienced air compressor experts at Compressor World.
