When air is compressed, the humidity in the air is concentrated into a smaller area, frequently condensing inside the blasting pot and/or air hoses. This will consistently cause moisture clogs in your sandblaster if you haven't taken adequate precautions. If the area in which you live regularly has humidity levels over 50% during part or all of the year, you should be using a high efficiency water separator in addition to the medium efficiency separator supplied with your Glastar pressure sandblaster.
These extractor/dryers are among the best available today. They provide full 2 stage filtration plus a coalescing effect for highest efficiency. The filter elements are inexpensive and easily replaceable.
