Different air set up Hypertherm 30 XP - what filter?

admin

So, I have a different air set up due to my limited shop area and I'm wondering if I need anymore filtration for my Hypertherm 30 XP. My compressor is a 15 gallon 110v (5cfm) set up inside my air conditioned fully climate controlled shop. Room humidity is usually in the 40's or 50's - I'm in Louisiana. My shop has a wood floor, so I use my plasma and my welder outside on a concrete covered area. I have 6" of 3/8 gas pipe running through the wall to connect to air while outside. My set up is compressor (inside) - 25' hose reel - pass through - 6' air hose - plasma. I called Hypertherm and explained my set up. I was told I may be ok with no extra filters for the plasma. I'm thinking maybe a little insurance wouldn't hurt. Plus if I want to paint... Motor guard? I've read on forums they're best for oil and just ok for water. Don't know if that's true?2 stage coalescent/desiccant filter? No extra filter?Miller 215Evolution S355CPSLRevolution 4 2x72Hypertherm 30XP
Reply:This is what I use for ALL my shop air. Including the hypertherm PM45I also have an auto drain which you can see on the bottom right hand of the compressor picture.  And one drip leg. This may be overkill for my little two car garage,But maybe not.  Don’t forget the hypertherm also has an internal water separator.  If you take the cover off you will see it.  Run whatever you want….I have been very happy with my particular set up.   Actually I just noticed that I’m due to change the desiccant beadsDry equals blueMoisture equals pink.  I buy them in bulk and keep the saturated ones until the winterI put them on a steel tray next to the woodstove and they are blue again in about an hour.   For the amount of air I use in the shop I only really have to change them maybe once every two months.  Air is very dry.  Never had a problem with the plasmaOr occasional painting.
