I’m using my this same dryer with a portable Sanborn air compressor. It has two cylinders (not sure if that specifically means it’s 2-stage). I had to dial up the cut out pressure a bit on it but it’s still within the specifications of the tank. I believe it cuts out now at 150 or 160… i could check tonight for specifics. I believe I’m set up to send 75 or 80 psi out of my equipment room out to my plasma cutter. But I have been extremely impressed with the air quality! I also run it through a refrigerated dryer but only when I’m actually using my plasma cutter. But I’m really not sure I even needed the refrigerated dryer to be honest. As long as you keep that 45-50psi pressure drop or more across that dryer it works great!
My only word of awareness (providing you stay within the safety limits of the compressor of course) would be to acknowledge how much you plan to use your cutter and how long each project will take to burn. I don’t believe the cfm of my compressor is quite the same as the cfm consumption of the Razorweld plasma cutter I have… so if you have extremely long cutting process for projects you could perhaps exceed the ability to maintain adequate pressure drop across a non refrigerated dryer like this.
Another thing to consider is with a smaller compressor and long cutting process you could have issues where the compressor runs so much that the compressed air becomes quite warm. Even with the 45psi pressure drop you still won’t see the reduction in dew point that you would with cooler compressed air Temps. This is why you see after coolers being installed.
Just something to consider
