Sandblasting compressors

Sandblasting is an effective way to clean and restore parts and assemblies by removing paint, rust, coatings, and more. To get the best performance from your sandblaster, it is crucial to select the right compressor for the job. Here are some essential considerations and guidelines for choosing a suitable compressor for sandblasting:

Compressor Requirements for Sandblasting:

Sandblasting is extremely demanding on compressors, requiring a constant and high airflow. The compressor size and specifications will depend on the scale and nature of your sandblasting tasks. For smaller sandblasting jobs, a compressor delivering between 10 CFM and 20 CFM is recommended. If you require more power, opt for a compressor with a CFM between 18 and 35. Industrial-scale sandblasting demands a compressor capable of producing 50 CFM to 100 CFM or more.

CFM (Cubic Feet per Minute) and PSI (Pounds per Square Inch):

The volume of air that the compressor can move in a minute (CFM) and the pressure generated (PSI) are critical factors in selecting the right compressor. The size of your sandblaster and nozzle will dictate the required CFM and PSI. As a rule of thumb, a higher PSI correlates to a higher CFM. For instance, a No. 2 nozzle at 100 PSI necessitates a compressor with a CFM of 20, but the same nozzle at 140 PSI requires a CFM of 28.

Compressor Size and Nozzle Selection:

The size of your compressor should align with the size of your blast nozzle. Larger nozzles necessitate higher CFM and air reserve. If you're working with large pieces of sheet metal, consider using a #6, #7, or #8 nozzle, ranging from 3/8 inch to 1/2 inch. For more precise projects requiring a smaller blast pattern, opt for a #4 or #5 nozzle, measuring 3/16 inch or 1/4 inch, respectively.

Compressor Efficiency:

For optimal efficiency in abrasive sandblasting projects, it is recommended to use a compressor with a minimum PSI of 100. Working with a lower PSI will significantly increase the time required for your project. For example, if you reduce your blasting pressure by half, your project will take four times as long to complete.

Power Source Considerations:

When choosing an electric air compressor, consider the power source available at your location. Most residential settings have access to 120 volts, while 240 volts is less common. Gasoline-powered air compressors are also an option but tend to be more expensive than their electric counterparts.

Sandblasting Cabinet Compatibility:

Sandblasting cabinets, a popular choice for sandblasting, often specify the CFM and PSI requirements. Ensure that your compressor meets or exceeds these specifications for optimal performance.

Example Compressor Options:

• California Air Tools CAT-10020C: This compressor, priced around $350, delivers a CFM of 5.3 @ 90 PSI and is suitable for smaller sandblasting tasks.
• Harbor Freight Sandblaster with a 60-Gallon Sanborn Compressor: This setup provides ample power with a CFM of 11.5 @ 90 PSI.
• Towable, industrial-sized compressors: For large-scale sandblasting, these compressors offer significant power, making short work of metal pieces.

In conclusion, selecting the right compressor for sandblasting depends on factors such as the scale of work, nozzle size, desired efficiency, and power source availability. By matching the compressor specifications to your sandblasting requirements, you can achieve efficient and effective results in your cleaning and restoration projects.

Sandblasting media

When it comes to sandblasting, the type of media or abrasive you use is important. The right choice of abrasive for a particular application can make all the difference to the outcome of your project.

There are two main categories of abrasive media: those for dry-media blasting and those that can be used for both wet and dry blasting. Dry blasting-specific media cannot be used in wet blasting applications as the material does not sink in water, which is a key parameter for successful wet blasting.

Dry Blasting Abrasives

• Sugar sand: A round media used for light duty dry blasting, cleaning, and stripping coatings. It produces superior results compared to angular particles and is a great option for surface preparation projects.
• Corn cob: An organic, soft media made from crushing the woody ring of a corn cob into multiple sizes. It is ideal for delicate surfaces like wood.
• Walnut shells: Organic, angular abrasives for mildly powerful stripping without damaging the surface. This media is beneficial for cleaning dirt, grease, oil, carbon, and paint without changing the underlying substrate.
• Sodium bicarbonate: A mild abrasive with a MOHS Scale of hardness rating of 2.5. It will not leave an unwanted surface profile on the material and is great for cleaning and fire restoration jobs as it effectively deodorizes.

Wet or Dry Blasting Abrasives

• Steel grit: An angular abrasive used for fast stripping and aggressive cleaning. This media is great for cleaning metal surfaces covered in dirt, rust, mill scale, or paint.
• Steel shot: A spherical-shaped abrasive used for cleaning, polishing, peening, and descaling.
• Aluminum oxide: A sharp, long-lasting media for fast glass etching and profiling. This media is ideal for industrial operations, such as cleaning turbine blades and engine parts, and is used in anti-skid applications.
• Glass beads: Used for general cleaning, peening, and cosmetic finishing of sensitive surfaces. They produce a bright, satin finish.
• Crushed glass: An efficient, angular abrasive that is free from crystalline silica and made from 100% recycled glass. It produces a cleaner finish than most slags and is cost-effective.
• Garnet: An angular, hard media commonly used in place of silica sand. This fast-cutting abrasive works great for removing tough coatings, paint, rust, and mill scale from steel.
• Coal slag: An angular blast media that is a byproduct of coal. This abrasive is used to remove coatings like rust and paint from steel and concrete.
• Plastic: A soft media used for automotive and aerospace applications. It can remove paint and mold from delicate surfaces without causing damage and is less hazardous than chemical stripping.

Factors to Consider when Choosing Abrasive Media

The shape, size, density, and hardness of the media are important factors to consider. Angular media creates a textured surface, ideal for paint or finishes, while round-shaped abrasives will not leave a rough texture. Most abrasives are measured by their mesh size, which is defined by the number of holes in a screen the media can pass through per square inch.

Density is measured in pounds per cubic foot, with higher density abrasives having more impact on the blasted surface. Harder abrasives will also impact the blasted surface profile more than softer ones. Softer media, such as organic materials and plastics, are sufficient for removing dirt, oil, grease, and paint without causing damage.

Sandblasting applications

Sandblasting is used in a variety of applications across multiple industries. It is often used to clean and prepare surfaces before they are painted or coated with another material. This includes the removal of old paint or rust, or to roughen a smooth surface, such as concrete, so that sprays or rollers can apply a better bond. Sandblasting is also used to remove rust and corrosion from metal, create decorative effects on buildings, signage, and boats, and for fire damage clean-up.

Sandblasting is also used as an art form for graffiti removal, allowing for intricate designs and fine detail. This is often achieved through the use of templates to guide the blasting.

Sandblasting is further used to clean boat hulls, as well as brick, stone, and concrete work. It is also used for cleaning industrial and commercial structures, although it is rarely used for non-metallic workpieces.
