Sandblasting Industry
Sandblasting is carried out under high pressure to smooth a rough surface, roughen a smooth surface or shape a smooth surface to remove its contaminants. Sandblasting is the process of using pressurized liquid or compressed gas as a propellant to propel the abrasive. Sandblasting abrasive materials include glass marbles, garnet sand, aluminum oxide, etc. Sandblasting can be used to remove old paint, rust and grease; roughen or smooth a surface; remove corrosion; clean tools; improve aesthetic value, etc.
Painted Surface Preparation:
Sandblasting is commonly used in industrial painting applications to remove old paint, rust, and other contaminants from metal surfaces prior to applying a new coating. Industrial air compressors are often used to power large sandblasting equipment for this purpose.
Concrete Surface Cleaning and Restoration:
Industrial air compressors can provide the necessary airflow and pressure to push abrasives against concrete surfaces to remove stains, dirt, and other surface contaminants.
Graffiti Removal:
Sandblasting is an effective method for removing graffiti from concrete, brick, or stone surfaces. Industrial air compressors can provide the high-pressure airflow required to push the abrasives and effectively remove graffiti.
Metal Parts and Equipment Cleaning:
Industrial air compressors can be used to power portable sandblasting equipment or large sandblasting rooms, depending on the size and complexity of the job.
Fabrication and Metalworking:
Sandblasting is commonly used in the fabrication and metalworking industries to prepare metal surfaces for welding or other forms of joining. Industrial air compressors can provide the high-pressure airflow required to remove rust, dirt, and other contaminants from metal surfaces prior to welding.

Air Flow:
Air flow is measured in cubic feet per minute (CFM) and is a key factor in determining the size of the industrial air compressor needed for sandblasting. The CFM requirements for sandblasting will vary depending on the size of the sandblasting nozzle and the desired blasting pressure.
-
Pressure:
The air pressure required for sandblasting is measured in pounds per square inch (PSI). Most sandblasting equipment requires at least 90 PSI of air pressure to operate effectively, but some applications may require higher pressures depending on the hardness of the blasting surface.
-
Tank Size:
The tank size of an industrial air compressor is also an important consideration when selecting an air compressor for sandblasting. A larger tank will provide a steadier airflow and allow the compressor to cycle less frequently, which reduces wear and tear on the compressor motor.
