All compressors will get moisture in the tank. Normal operating practice is to drain the tank regularly. This prevents your tank from rusting out and helps to keep moisture transfer to your distribution system. It is helpful to cool the air as much as possible before it gets to you blaster. This can be as simple as a long metal distribution pipe or as complex as a refrigerated dryer. Finally, a filter/separator just before your blaster will keep any residual moisture out of your blaster.
It may seem like it is a lot of effort to eliminate moisture but you will be much more frustrated with clogs if you don't give it some consideration.
