    Plasma Cutter Air

    Upgraded from an old Everlast plasma cutter to this big ass Hypertherm. Do I need more dryer than what the previous owner has on the back of the machine?

    Short answer,

    I wouldn’t trust just that little guy.

      Any recommendations on which filter to get? I’ve never had this nice of a machine and want to make sure I don’t mess it up.

        I have been running the air dryer from harbor freight. Haven't had any problems with it.

          I second get a air drier and install it by your compressor. All your air tools will enjoy the water free air. Besides the air drier I have a big desiccant filter right before my cutter .

          The cleaner the air the longer your consumables will last. At $15-20 a set you want them to last as long as possible.

              I have a large dryer at my compressor and a dessicant dryer on the plasma cutter, have had 0 problems with this setup over 15 years.

                I'm setting up my Powermax 65 on a cart. What dedicated desiccant filters are you guys using? I already have a motor guard for the final filter

                  The one on the plasma is some generic name, plastic bowl style inline that I picked up at a local industrial supply house for about $50.
                  It is just extra protection in case something gets past the big dryer and oil filter system at the compressor.

                    I've got a large aftercooler before my tank that strips most of the water. My kit is mobile and don't really want to haul a dryer around, a desiccant filter will be needed. Filter size/prices cover a pretty big spread, Have you been happy with your generic filter?

                      allot of people go over kill with air dryers etc. to the point they can cause problems. if your running dryers be sure to put a gauge on the machine and know that its running in the 100-130 psi range.

                      i'm in the PNW and run my pm65 everyday on the cnc. without any airdryer. i have a water drop about 50 of line from the tank, then another 50' to the cutter. i have have less issue since removing the air dryer and motorgaurd filter.

                      also its worth saying that a hypertherm plasma is going to be way better than the everlast when it comes to dealing with moisture int he air.

                        I am a very light user of my Powermax45. It just has a motorguard filter at the machine, no drying at all. I'm sure I'd see more difference if I used the thing more, but as it is, my consumables last me just fine. I'm confident I'm doing it wrong, but if I can't tell the difference, I don't care.

                          the motorguard filter is most definitely filtering and drying. matter of fact the biggest issue i see is people using a motorguard filters and not replacing them enough. if its damp at all it needs repalced and i believe by mfg supposed to be changed weekly.

                          if you have a motorguard filter and it is not obviously wet or restricting air, i can 100% gaurentee there isn't any issue with air quality.

                          put in a couple extra feet of line off the compressor tank that allow the air to cool, moisture to condensate and fall back to the tank and your fine. air pressure at the machine is a far more important and overlooked issue.

                            Yeah, Its been working fine for a lot of years.
                            I have hooked up to other peoples compressors with nothing else and not had a problem with moisture getting by
