compressor filter

gillis - Thursday, July 3, 2008 - 11:19am

I'm looking for this water filter for my compressor, the one that uses the toilet paper kind of. It's for my plasma cutter. Would anybody have a picture of that filter and can anyone tell me where I can order it?

Thanks in advance...

Hi Gillis, it's called a water trap and should be available where they sell large air compressors or air tools. Mine cost around $70. You don't need a commercial trap($100-$300 cost), but I wouldn't buy a cheap one($20 from harbor freight) because you'll just spend extra $ in nozzles and tips on the torch. Make sure to put it right before the plasma unit otherwise you may still get water going into it.

I just checked in a store we have here in canada called Princessauto. They have a desiccant air dryer. I don't know if know about these? It's a 37" long tube with air dryer pellets that goes into that tube. They say that it recommended for quality spray painting and that it eliminates all moistures from air supply.What would you say about this desiccant air dryer?

As long as it doesn't mess with air flow it would probably work, but check these sites out. These are the type that i use.

you need a water trap, but

you need a water trap, but in addition, you should get a paper filter.
I use a Motor Guard M45- these cost about $75, and here in the USA, are available at any real welding supply store.
Or mail order, from all the big online welding supply companies

I change my filters out every couple of months (it doesnt use real toilet paper- that would disintegrate and foul your plasma cutter right away- it uses a round roll of much tougher paper) and I let the old, wet one, sit for a month or so, and dry out, and use it again. I usually get several uses out of each filter.

Princess Auto does not sell much of anything worth much, in my opinion- its the bottom of the barrel chinese imports.
You need to find the real welding supply store near you. If they dont have these, they can order em. Almost every commercial shop I have ever seen that uses plasma uses Motor guard brand.
