I currently have a Quincy QT-54 5HP piston compressor w/ 60 gal tank it's about 5yr old. It puts out about 15cfm at 100psi. I have it hooked up to an IR air dryer.
I have no issues with the compressor, except for the noise. I cannot put it outside. So I have been researching rotary screw models.
Specifically the Kaiser Airtower 5C, it comes with an air dryer built in to the unit.
It is mostly used for the CNC machine, and the Quincy cycles about every 10 min or so when the CNC is running, which can be for 10 - 15 hours straight depending upon the work.
Is this enough usage for the rotary screw? I do understand that the rotary screw compressor is substantially more than the Quincy but noise when the compressor is running would be very big motivator for switching.
