Dryaire Desiccant System

[ron in sc]

Does anyone use the dryaire desiccant system to remove moisture? I know Devilbuss make one too. I'm wondering how long the desiccant will last. I know that will depend on useage but I was just trying to get a general idea. Like for instance maybe they are a waste of money to use if you are sandblasting.

Not sure how long they will last as it will depend on how moist your air is, which in turn is determined by how well your system removes water from the air before it gets to the dessicant.

I would think about getting a refrigerated air dryer. Get one of these and any water problems should go away.

I have been using a dessicant filter that I built for 5years now without problems, I paint and blast all the time. Never do I see any moisture at my tools.
The cool part is the dessicant can be reactivated in an oven when all pink.

"a dessicant filter that I built"?

Come on now. You can't tease us like that and not tell us how you built one.

Do tell............

I recall that there's a lab product called Drierite that's chips of anhydrous calcium sulfate. When it hydrates, it turns pink - they must add a dye of some kind that's sensitive to the amount of moisture. I didn't realize you could bake it to reactivate, but that makes sense.

The trick would be to build a container for the Drierite that won't blow up when it's pressurized, and that will direct the air through a bed of Drierite.

I too would be curious to see how you handle this.

mine actually came as part of some lab equipment and is filled with drierite, it is made from acrylic and clear so you can tell when it is pink. A friend of mine made one similar to mine out of PVC with a sight glass towards the end, so he can tell when it is pink. I know you guys don't like PVC for Air , but Schedule 40 is plenty strong. Basically a pipe, an endcap and a cleanout plug...

Don't forget a filter after the Drierite otherwise you will get some powdered calcium in your lines....not good.

hehe..yeah there is a felt like filter at the end of your deccicant bed for that.

Oh, and these have both been in place for a long time, mine runs 110psi and his runs 125 psi...all the time. You don't have to like them, but believe me, they work.

His is similar to this...

Sorry to bring back an old thread, but I was wondering if anybody has any experience with this from HF?
