Among the many uses of a sandblaster gun, the most common is the removal of old paint and rust from metal surfaces. A perfect job however requires the best sand blaster gun. Yet only a few are able to offer that. While others might leave you feeling swindled and unsatisfied.
In this article, we are going to explore the different types of sandblaster guns, and list the best ones. We are also going to evaluate the buying guide to help you make the best choice.
Types of Sandblaster Gun
A sand gun is classified according to how it functions;
1. Gravity feed sandblaster
The gravity feed sandblaster utilizes gravity to feed the gun. It functions in a similar fashion to the gravity hopper used in paintballs. But in this case, what is in the hopper is abrasive material or sand.
When the trigger of the gun is squeezed air rushes through the barrel propelling with it sand that is sprayed onto the surface.
It’s most ideal for small jobs because of its limited capacity.
2. Pressure sandblaster
The pressure sandblaster is the most commonly used sandblaster because of its ability to work on large jobs. And for a longer period of time without the need for a refill. One reason for the longevity is that the sandblaster uses a large canister. A normal pressure blaster canister is well capable of swallowing a 50 lbs. bag of abrasive material.
Just like other sandblasters, the pressure sandblaster uses an air compressor. The compressor propels the sand in two ways; a valve on the side of the canister directs air into the canister Pressurizing the sand and pushing it towards the bottom where an exit valve is present.
The same air from the compressor is externally directed to the exit valve at the bottom. To collect the sand as it exits from the canister. It propels the sand to the gun where the user directs it onto the desired surface.
3. Suction/ Siphon Sandblasting
The siphon sandblaster gun utilizes low pressure to suck in sand, or abrasives from a container placed on the ground and spray it onto a surface. It’s one of the cheapest sandblasters available on the market. But its efficiency largely depends on the suction force which in turn depends on the PSI of the pump.
We also have pressure washer sandblasting kits that easily convert your pressure washer into a siphon sandblaster. You only require a pressure washer with adequate pressure ideally greater than 4,000 PSI.
