Good plasma air filter / dryer

Dec 09, 2004 11 Replies

Any recommendations on an air filter/dryer for my plasma cutter? It's a Powcon Plasma Plus (50 amp) unit. I use it in my home garage for hobby stuff. I live in SC where it is very humid in the summers. My air compressor has a cheap air/water seperator on the outlet. I'm looking for something that I can attach at the plasma unit and also possibly use when painting. Thanks.

Air dryers tend to be voracious air users. Consider a bottle of nitrogen instead?

Go to a professional paint supplier and buy the type that uses a roll of what looks like toilet paper.

try plumbing the garage with copper tubing and vertical drains

Hello Jason

Take a look at the Motor Guard M-26. It is considered one of the better units.

Some air dryers use dessicant. The dessicant is then dried by running heated air (from the downstream side of the dryer) thru it. This heated drying air is vented to the outside as it is full of moisture. I suppose this is the type of dryer Winston is speaking of.

I've got the Motorguard roll filter unit. We also often have pretty high humidity during the summer.

I have an 80 gallon air tank, mounted on end. This gives water a nice place to pool. Every time the compressor turns on, a valve in the base of it blasts for a fraction of a second (using a time delay relay from the scrap yard). Air goes through overhead pipes to drop points, each one having a drain pipe to accumulate water. The part that surprised me was I get *no* water accumulation at the drains. It all seems to go away at the tank.

Yes. Thanks, Shawn. That's what I was talking about.

Aha, now I get it.

What are the advantages of this dessicant kind of air dryer system, rather than the refrigerated type? (Clearly the disadvantage is that it uses more air!)

Andy

Dessicant type dryers will produce air with a much lower frost point.
