Air compressor question:
I like/want/need a source for compressed air in my workshop.
But I can't take the loud and annoying noise form a standard air compressor. Can't annoy my neighbors by putting it outside either.
Yes, I know there are silent (refrigerator) types available, but they're prohibitively expensive.
I don't need LOTS of air, only maybe 10-20L/min or so on average.
Question now is:
Can I use a standard "piston type" air compressor with a variable-speed control, to get motor RPM (and thus the noise) down to acceptable levels - or is this a no-no with standard-type air compressors?
The reason I'm asking is that I haven't seen this done (or even mentioned) anywhere before - yes, I googled already - so I'm guessing that there must be some hidden problem in going this route?
Yes, I realize that I'd get much less air flow amount. And yes, I know i must run a speed control appropriate for the motor in question - inverter/frequency-changer for phase-controlled induction type and probably SCR/dimmer type for universal motors.
