Narrowing Down Your Search For Sandblasting Equipment

Posted On August 12, 2015



Sandblasters use finely ground silica sand, one of the most common varieties of sand found around the word and often used in industrial processing, to clean typical metal surfaces of any rust, paint, or other unwanted material staining the given metal surface. It is combined with air-powered pressure, like many other blasting cleaning machines, but if you’re looking for Sandblasting Equipment of your own, you have to keep in mind that there isn’t just one type of Sandblaster—there are actually three.

  1. The Gravity-fed Model

As the name implies, this type of sandblaster uses gravity to get the job done. There are three parts to this model: the pressurized air tank, the pressure gun, and the hopper. The sand is placed in the hopper, which is a container that is mounted on top of the gun. The gun is then hooked up to the air compressor, and when the trigger on the gun is pressed, the air blasts out of the nozzle and then the sand falls from the container.

  1. The Pressure Blaster

Much easier to use than the other types, it is also more expensive. A sandblasting gun is connected to the port at the top of the canister via a specialized host. When the gun trigger is pulled, the air and the sand are simultaneously forced out of the nozzle. One of the drawbacks to this model is that the sand cannot be collected or reused.

  1. Siphon Sandblaster

Similar to the aforementioned gravity-fed sandblasters, the Siphon sandblaster still has something that makes it unique. The difference is the location of the hopper. Instead of being above the nozzle, the hopper is located below it. When the air is released, the sand goes to the nozzle through a suction-like process.

Once you’ve decided on which model is best for you, consider what size you would like your sandblaster to be. Mini sandblasters are portable and were specifically designed to assist in detail work and tight spaces, whereas larger

sandblasters need to be mounted in order to be kept stable, and are more generally used to remove old paint from a house before repainting or renovating.  

The machine itself isn’t the only thing that comes in different sizes. You can get one that has a larger hopper to hold in more sand, search for a model or accessories that allow for a comfortable pistol grip to help with the elimination of blisters and extend your time in being able to use your blaster, or get a larger fuel tank in order to avoid constant refilling.

The machine isn’t something that always comes fixed—plenty of things are adjustable, and there are some features you might want that you didn’t even know were offered (like built-in lights and various sized nozzles).

That’s why it is important that you do your research before going into a store to make a purchase, and if you do go into a store without doing any research, at least start with knowing what you need it for. What do you want to accomplish with the sandblaster? This will guide you in the right direction and you will be able to find one that best suits your needs.
