The 40 lb pressure pot size also has other aspects that are a plus in comparison to the smaller 20 lb blaster. But these additional items aren’t expensive and can be easily added to the 20 lb blaster. These additional aspects are included on the Central Pneumatic 40 lb pressure pot:
- The use of a pressure gauge, so you can monitor the pressure and adjust the air pressure setting for the desired glass etching power. (A pressure gauge isn’t expensive and can be connected later if desired, but not needed.)
- The use of an air/water filter (a.k.a. air separators), so moisture and contaminants are extracted from the compressed air before being placed in the pressure pot. This should definitely be used to prevent moisture from getting mixed into the abrasive which causes it to harden. If this happens the abrasive will need to be removed from the container and dried. (Good air filters are also fairly inexpensive, as low as $10 and can be connected anytime.)
