Air compressor sale
Depends on what you will use it for. The 175 PSI is normally a two stage which builds pressure but not so much volume. I have a Devil-biss 80 gallon upright that came with a 175 PSI two stage compressor and would not stay up with the bead blasting cabinet that I use a lot.
When the pump wore out I replaced it with a 2 cylinder/single stage pump.
The difference is that a two stage pump uses the 2 cylinders to build the pressure up, meaning 2 rotations to one power pump.
A single stage is pumping every rotation but at a lower pressure, normally 140-150 PSI. This give more volume.
My compressor now catches up and shuts off while I blast where the other pump ran continuously.
Two stage for pressure, single stage for volume.
