In this post, I’ll explain the benefits of using a pressure pot sandblaster, and also discuss some of its negative aspects. This system is recognized as the best type to use because it can be carve into the glass.
About the Pressure System- The pressure pot setup is configured so that an air hose connects the air compressor to the top of a sealed abrasive holding tank. Then, the tank gets pressurized with the mixture of compressed air and abrasive particles. There is another hose connected from the bottom of the tank to the nozzle that carries the pressurized abrasive and air mixture. This nozzle is what you will hold, and use to etch your glass.
- Positive Characteristics: First, it has more blasting power which allows you to do 3 dimensional works (known as sand carving and multi-staging sand etching), and finish artwork quicker so you won’t feel frustrated. Second, it uses less air, allowing you to buy a smaller, less expensive air compressor, which will likely have less wear and tear as a result.
- Negative Characteristics: This is generally a very expensive setup, but I will show you where to get one cheap, and save help you a lot of money. Also, these units don’t have a trigger feature which is typically very convenient and desirable.
Cost Effective Pressure Pot Sandblaster Solution
The majority of these systems are in the price range of $500 – up to a few thousand dollars. There are a very few systems that are less than $500 which are made by Chinese manufacturers and sold as many different brands such as Central Pneumatic. I have found some places that even cost less than $100. The only negative aspect of this pressure pot system is its lack of perfect consistency of abrasive flow, which I will explain later in the members area.

ok, where do I get one cheap?
There are a few places that have fairly inexpensive pressure pot sandblasters. One place is Harbor Freight but they have some inconsistent abrasive problems sometimes. I talk more about others in my info manual. Can’t remember all of them off the top of my head.
