I think it’s great. A 60-gallon tank can be drained pretty quickly by this machine. I don’t have a pressure regulator on it, so I think I’m at about 155 psi.
Some times I have to spin the wheel on my workpiece in order for it to move. I think a little grease in the head will solve that.
All in all, I think it’s a great addition to my metal-working tools. Get a good water separator because running the compressor so much makes a lot of condensation in the air. This will help. Then, even with a small filer, the fumes go out the back.
If I had to rate this, I would say that it is at least low to medium duty.
