Understanding Sandblasting and Its Requirements

1.     What is Sandblasting?

Sandblasting, also known as abrasive blasting, involves propelling abrasive material against a surface under high pressure. This process is used for removing old paint, rust, or preparing surfaces for painting and coating.

2.     Key Components of a Sandblasting Setup?

A typical setup includes an air compressor, a blasting gun with a nozzle, abrasive material, and a protective cabinet or area.

3.     Why the Right Air Compressor Matters?

The efficiency of sandblasting heavily depends on the air compressor used. It needs to provide consistent airflow (CFM) and pressure (PSI) to effectively blast surfaces.

Types of Air Compressors for Sandblasting

1.     Reciprocating Air Compressors: Ideal for small-scale projects, these compressors are affordable but offer limited CFM and PSI.

2.     Rotary Screw Compressors: Known for their reliability and higher CFM output, suitable for continuous use in larger projects.

3.     Centrifugal Air Compressors: Best for industrial applications, offering high CFM and PSI but at a higher cost.

4.    Comparison of Different Types: Each type has its pros and cons, depending on the project size and requirements.
