Desiccant Filter – Why and How

Why you should use a Desiccant Filter with your Engraving System and Sandblasting System.

A desiccant filter is a great way from preventing moisture from reaching your engraving equipment or contaminating your sandblasting system.

When air is compressed, moisture and heat are created. When moisture is exposed to heat, it turns to vapor. Vapor can and will pass through a standard filter/regulator. A Filter/Regulator is great for removing water in a liquid form, but vapor will pass through. As soon as the vapor cools, it turns back into liquid, reaching your engraver or the sand in your sandblaster.

How do we prevent this from happening?

We install a desiccant filter as another method of removing moisture from compressor air.

Profitable Hobbies desiccant filter is easily adaptable for use with any engraving system or a sandblasting system and works great for those needing additional moisture control.

Moisture is your #1 enemy when it comes to pneumatic tools – especially micro sandblasters!

The installation is simple, and when the beads turn from blue to pink, just toss them into the oven (not literally) and bake them at 275 degrees until they turn pink again. The beads can be dried and re-used over and over again.

    I have the shufu high speed engraver. Oilless. do I need special fittings with the Desiccant filter?

    Thank you!

    Jackie, it just depends on the fittings used to connect your air hose to your regulator. The desiccant filter will work great with the shofu (or any other handpiece). The only thing you might run into is the quick connects might be different on your system – unless you are using Profitable Hobbies regulator, then they will work fine. If the quick connects are different, you will just need to get the right ones. The threads on the ends of the filter are standard 1/4″ pipe threads which are very common and easy to adapt to.
    Hope this helps.
