The terms “sandblaster gun,” “blast cabinet gun,” and “sandblasting gun” all refer to the same thing: an air-powered device that directs an abrasive material towards a surface. Gun controls and valve types determine the specifics of their form and function. The most common varieties of sandblaster guns are those that are activated by a trigger or foot pedal. Users may easily start and stop the flow of abrasive media by pressing and releasing the trigger on this device.
Long periods of time spent pressing the trigger on a sandblast gun can be tiring. A foot pedal-operated cannon, on the other hand, gives the user greater say over the intensity of the blast and may be used for longer without creating fatigue or pain. The sandblast gun’s nozzle holder is where the abrasive medium is discharged. The media is sucked up via the gun’s pickup tube into the chamber. The air supply may be turned on and off with the press of a foot pedal switch located between the air source and the pistol.
Rust and old paint may be easily removed from metal surfaces by sandblasting. Sandblasters may be broken down into three categories: those that rely on gravity, those that rely on pressure, and those that employ a siphon. An air-powered pistol is used to propel the sand to the surface at great velocity.
Nonetheless, due to the potential for harm, appropriate safety measures must be taken. The hopper at the top of the gravity-fed cannon is used to load sand into the barrel. Nevertheless, the pressure blaster requires a pressurized sand canister.
Finally, sand is drawn through the cannon of a siphon sandblaster. The sand may be gathered and reintroduced to the reservoir for future reuse, reducing the overall cost of the system.
When searching for the perfect sandblasting gun in 2023, there are several features and functions that you should consider. The size of the gun is a critical factor, as larger industrial-grade options may be necessary for big projects, while portable versions are perfect for automotive and home uses. The airflow strength is another crucial element to consider, as the higher the airflow, the more effective the job will be. The blasting pressure is also vital. Higher pressure can efficiently remove dirt and paint from surfaces. When looking for sandblasting guns, some notable features include comfortable pistol grips, adjustable pressure controls, different-sized nozzles, and even reusable components.
In addition to the features and functions of sandblasting guns, it is also important to consider the type of sandblasting media that you plan to use. For instance, coal slag and garnet are excellent options for surface preparation, while soda blasting works well for thin metal bodies and restoration work. Steel media, on the other hand, is an ideal option if you can recover your blast media as it can be recycled up to 100 times.
When choosing a sandblasting gun, it is essential to keep in mind the valves that work best with specific blast media. Some brands offer valves that can use any blast media, while others have valves that are specific to consumable medias like coal slag or crushed glass. Blast pot size is another critical factor to consider. In general, blast pots are listed in cubic feet sizes. Each cubic foot of blast media will allow for about 3-5 minutes of blast time before requiring a refill.
You should consider the safety remotes and options, including how much blast hose you will want to run from your blast pot and whether you want to include options like an abrasive cut off switch or a pressure hold design. Industrial painters must consider several factors in choosing the best sandblasting gun, from size and airflow strength to blasting pressure and safety options. By considering these criteria, you can find a sandblasting gun that meets your specific needs.

Q: How do sandblasters work?
A: Sandblasters work by metering compressed air into a suction-blast gun through its air jet venturi effects, generating a powerful vacuum in the media delivery hose that draws media particles up to the gun. The mixture of media and air is regulated by a pickup tube located at the bottom of the media supply hopper or blast cabinet. The pickup tube vent allows the right balance of air and media, producing the maximum number of media impacts per second to clean or prepare the surface.
Q: Why should you select sandblasting machinery instead of other cleaning and surface preparation methods?
A: Sandblasting machinery is an effective method of cleaning and surface preparation because it is versatile and can handle a variety of surfaces, shapes, and sizes. It can clean surfaces faster with less effort, and it does not leave residue on the surface. The process is also environmentally friendly, as it does not use any chemicals or solvents.
Q: What should you do if your sandblaster is clogging?
A: If your sandblaster is clogging, turn off the compressed air supply and remove the nozzle from the blast gun. Inspect the gun body for any debris that may be blocking the flow of media. If the gun is clear, check the media intake of the pick-up tube for any debris that may be blocking the flow.
Q: Why does the sandblasting gun have the problem of air leaks?
A: The sandblasting gun may experience air leaks if the connection between the compressor pipeline and the tools has air leakage. To fix this, wrap the Teflon tape around the connection. Installing an air control unit in the air compressor and an air filter at the air inlet of the sandblaster may also help.
Q: What should you do if the media does not eject or the sandblasting gun does not work?
A: If the media does not eject or the sandblasting gun does not work, check the air source pressure. It should be over 90 PSI. Adjust the abrasive valve to control the amount of media. Use an acceptable abrasive size of #46 to #220 to prevent blockages. If the problem persists, it is recommended to use a harder abrasive, such as steel grit or aluminum oxide.
Q: Why does the sand blaster use too much media (abrasive)?
A: The sandblaster may use too much media if the operating pressure is too high, or the abrasive valve is open too much. Adjust the parameters to control the amount of media used.
Q: Why does media pour out of the sandblaster tip?
A: It is normal for the media to pour out of the tip if the valve is open. Even if the valve is closed, some media may be left in the chamber, causing it to pour out. It is recommended to refer to the video guide if the siphon-fed cannot work. Ensure that the gap or small hole of the tube is not covered by the media.
Q: Why do you need to refill the hopper often?
A: You need to refill the hopper often to ensure a consistent flow of media. If the hopper is empty, the media flow will be inconsistent, affecting the efficiency of the sandblaster.
Q: Why is the sandblaster not powerful?
A: The sandblaster may not be powerful enough if the air compressor is below two hp or the operating pressure is below 90 PSI. Check the connection between the compressor pipeline and the tools for any air leakage. Use an acceptable abrasive size of #46 to #220. If the problem persists, it is recommended to use a harder abrasive, such as steel grit or aluminum oxide.
