Water Filter Advice

Postby Jfile » Thu Jun 07, 2018 11:13 am

I'm getting a new table in a few weeks and was looking for advice on a good water filter. I have an automatic purge valve on the bottom of my compressor and I have a small inexpensive 2 stage filter just a few feet after the air leaves my compressor. Those seem to do a pretty good job but there will be about 25 foot of line from that point until it gets to the plasma cutter and I feel like I should have additional filtering at that point. What would you guys recommend? Thanks in advance for any assistance.

What you want is really an air dryer, many here use the refringent type or the desiccant type and other use a series of tubing and fans to cool the air.
These help to have the humidity in the air drop out and return back to a drain point.
Do a search for air dryer here and you can what is used.

I was gun shy about buying the Harbor Freight unit as some of the feedback isn't positive. Poorly assembled, freezing up, etc, etc. I bought this Schulz unit off Ebay for $725 to my door and man is it nice. I haven't hooked it up yet as I'm waiting for stainless steel whip hoses to arrive and a coalescing filter that will go between the cooling manifold I made and the dryer.

Not sure why the pic is showing sideways but if you click on it, it shows upright.

Thanks to all who have replied. I think I have decided to go with one of air dryers not too far from the plasma cutter and then add one of the motor guard filters right behind the plasma unit. I read several good reviews on the Harbor Freight dryer so I'm thinking about giving it a try. Wasn't planning on spending that kind of money but from everything that I've read, you can't go wrong with multiple methods of filtering and drying the air used for cutting. Being a beginner, I want to avoid any thing that might make it more difficult to produce good clean cuts.

Thanks again for all of the advice.

I'm not going to lose sleep over $24 and I doubt my air system will ever exceed 200psi. Plus the stainless is prettier. LOL
