The size and capacity of a sandblaster, as well as its working air pressure and the type of blasting media it can use, are all crucial factors to consider when shopping for the right model for a job.
Though it may seem a bit daunting to figure out which is the right type of sandblaster to buy, choosing the best option depends largely on the type of application. Ahead, learn about the three main types of sandblasters: gravity fed, pressure, and siphon.
A gravity-fed sandblaster consists of a spray gun with a small hopper on top that holds the sandblast media. The sandblaster attaches to a standard compressor tank, which produces the force needed to drive the media through the gun. As the gun blasts out the media, the force of the air and gravity cause the media from the hopper to drop into the chamber.
This type of sandblaster is compact and doesn’t require a large tank or bin to hold the media, often making it the best choice for home use andideal for DIYers who may use a sandblaster only for occasional projects.
A pressure sandblaster comes equipped with a large, pressurized, 10-pound metal drum that holds the sand media. A spray gun attaches to the canister via a rubber hose. When it’s turned on, pressure created inside the tank forces the media outward through the hose and the gun.
Since the sandblaster tank is pressurized, it is capable of blasting media at a very high speed—typically around 120 pounds per square inch (psi)—making it ideal for stripping stubborn paint, rust, and corrosion off metal and concrete surfaces.
Pressure sandblasters are large, heavy, and expensive, so they are typically suitable for professionals who use a sandblaster on a regular basis.
A siphon system, like a pressure system, draws the sandblasting media out of a large container through a hose and out of a gun. But unlike the container in a pressure system, the container in a siphon system is not pressurized, so the gun must be attached to a compressor.
A siphon system produces similar power to that of a gravity-fed sandblaster, but its larger container allows it to run longer before the media must be refilled. A siphon system is also bulkier and costs more than a gravity-fed sandblaster.
Sandblasters can vary significantly in size and in the amount of media they can hold. The gun itself should be relatively small and lightweight so it’s easy to hold and manipulate while sandblasting.
Most guns are around 8 inches long and weigh about 2 pounds. Because their design has the reservoir with the media attached to the gun, gravity-fed sandblasters are a little heavier and bulkier.
Capacity can vary significantly depending on the type of sandblaster. Since a gravity-fed sandblaster’s reservoir is relatively small—typically around 20 to 25 ounces—it has far less capacity than a siphon- or pressure-style sandblaster, which can hold as much as 50 pounds of media.
A sandblaster requires a certain amount of air pressure inside the tank, and most sandblasters have a range of between 60 and 125 psi. The higher the working psi, the more power a sandblaster has to strip paint, rust, and other materials. It’s important to pair a sandblaster with a compression tank that produces enough pressure to power it.
In addition to psi, the air compressor must also meet a minimum airflow rating, which is the amount of cubic feet per minute (CFM) of air that the compressor is able to move. Some air compressors require a minimum CFM of 7, while others demand a CFM rating of as high as 12.
Blasting media comes in a variety of different materials—including glass beads, sodium bicarbonate (baking soda), and grit—to meet the needs of the different types of sandblasting projects.
Glass beads are ideal for projects that demand a glossy finish, while baking soda is the best choice for cleaning items with a significant buildup of grime or rust. For heavy-duty blasting jobs, grit or alloy shots are usually the best choice.
Since not all blasting media is compatible with all sandblasters, it’s important to look at the sandblaster’s blasting-media grit-size rating before purchasing it.
Knowing what type of media to use when operating a sandblaster is crucial to employing it safely and effectively. Ahead, learn more about sandblaster media and other important information regarding this type of power tool.
Sandblasters prep surfaces for a new coating by propelling media against a surface under high pressure, removing dirt, rust, paint, or other stuck-on material.
No. In fact, using real sand is a major respiratory hazard. Using sand that has more than 1 percent free silica can cause silicosis, which is a very serious scarring or hardening of the lungs that can be fatal.
Subfreezing conditions are not ideal for sandblasting. Sandblasting creates condensation inside the gun that can freeze, clogging the gun.
The best media to use for sandblasting is silicon carbide. This is the hardest material you can use to sandblast, making it the media of choice for removing stubborn rust and old paint from objects.
If you’re removing rust from a material that can be potentially damaged by sandblasting, such as aluminum, use glass beads, walnut shells, or plastic media, all of which will remove the rust but won’t damage the metal. Glass beads and aluminum oxide are good blasting media for harder materials such as steel or iron.
Rather than considering how big a sandblaster you need, it’s better to consider what type. A gravity-fed sandblaster is affordable, easy to use, and compact, making it ideal for those who may use a sandblaster only occasionally.
Pros or those using a sandblaster regularly may want to consider a siphon- or pressure-style sandblaster, which offers higher capacity and greater sandblasting pressure for heavy-duty jobs.
