Air compressors as a reliable and efficient power source

Applications of Air Compressors in  Sandblasting.

Origins of the Sandblasting Industry


Sandblasting has its origins in the late 19th century, when it was first used to clean and prepare masonry surfaces. Over the decades, it has become an essential tool in the construction, engineering, and manufacturing industries, due to its wide range of uses. From cleaning and preparing surfaces to creating decorative effects, sandblasting is an invaluable tool in many industries.

Sand blasting is also known as abrasive blasting, which is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but provides a more even finish with no problems at corners or crannies.

Sandblasting can occur naturally, usually as a result of particles blown by wind causing aeolian erosion, or artificially, using compressed air. An artificial sandblasting process was patented by Benjamin Chew Tilghman on 18 October 1870. Thomas Wesley Pangborn perfected the idea and added compressed air in 1904.[Source: wikipedia]

The Role of Air Compressors in Sandblasting

Air compressors are an essential component of the sandblasting process, providing the power necessary to propel the abrasive particles at high speeds. Without the right air compressor, the sandblasting process cannot be completed efficiently.

Sandblasting requires a large volume of air at a pressure that is higher than normal. The air compressor must be powerful enough to produce this pressure and must be able to maintain it during the entire process. Additionally, the air compressor must be able to withstand the harsh environment of sandblasting.

CFM Requirements For Sandblasting:

  • For sandblasting, having a higher CFM air compressor is recommended.
  • A compressor with a CFM rating ranging from 10CFM – 1500CFM can be ideal for sandblasting tasks.
  • If you want a more powerful sandblasting experience, then a compressor with a CFM rating of between 185CFM 、375CFM 、750CFM should be suitable for industrial sandblasting. It is important to note that the higher the CFM rating of the air compressor, the better.
  • Sandblasting is quite demanding on the compressor, requiring a lot of airflow constantly, to avoid having to stop and let the compressor catch up.

What factors should be considered in determining the size of an air compressor needed for sandblasting?

When selecting an air compressor for sandblasting, various key factors need to be considered to ensure efficient and effective operation:

1. Air Flow Rate (CFM – Cubic Feet per Minute):

The CFM rating of an air compressor indicates the volume of air it can deliver. The choice of CFM requirement largely depends on the sandblasting nozzle size used; larger nozzles need higher CFM to maintain adequate pressure, while smaller nozzles require less. Generally, a nozzle size of 1/8 inch needs at least 15 CFM.

2. Pressure Requirements (PSI – Pounds per Square Inch):

The effectiveness of sandblasting also hinges on the air compressor’s ability to deliver air at sufficient pressure. The standard operating pressure for most sandblasting operations is around 90 PSI, although more demanding tasks may require higher pressures to achieve the desired surface finish.

3. Tank Capacity:

A larger tank ensures a steadier airflow and allows the air compressor to operate with fewer start-stop cycles, which can extend the compressor’s lifespan. The size of the tank should be chosen based on the duration and intensity of sandblasting tasks to maintain performance without frequent interruptions.

4. Task Size:

Consider the scale of the projects. For smaller, less intensive jobs, an air compressor with a capacity of 10 to 20 CFM may suffice. Medium to large-scale operations typically require compressors that can deliver between 20 and 35 CFM, and for industrial-scale, heavy-duty blasting, a system offering 50 to over 100 CFM may be necessary.

Choosing the right air compressor involves analyzing these factors based on the specific requirements of the sandblasting tasks at hand. A well-sized compressor will not only handle the demands efficiently but also operate reliably over time.

How to Choose the Right Air Compressor for Sandblasting

Choosing the right air compressor for sandblasting can be a difficult task. There are a few key factors to consider when making your selection, such as the application, the power, flow rate, and pressure requirements, and the environment in which it will be used.

When selecting an air compressor for sandblasting, it is important to choose one that is designed for the specific application. This ensures that the compressor has the necessary power, flow rate, and pressure for the job. Additionally, it should also be designed for corrosive environments and have an enclosure that protects the engine from the elements. Finally, it should be easy to maintain and have a long service life.
