Which reminds me of my recently acquired compressor and a question that's
been puzzling me:
Compressors are known to be pretty noisy, generally, but what makes some SO
much noisier than others?
I'd owned a smallish Campbell-Hausfeld (5 gal., 120v, 100 psi, oil-lubed)
for some 25 years. It sounded like a freakin' machine gun when
running. I'd flee the garage after turning it on while it reached
pressure--or wear ear protection.
Then a few months ago I had the good fortune (Freecycle--gloat!) to come by
a larger and older Sears unit (no model number visible, but likewise 120v,
100 psi and oil-lubed). This one is probably 10 or 15 gallons and has two
cylinders (though still single-stage).
And it is MUCH quieter! No sharp edge to the sound as with the smaller C-H
compressor.
So why is that? What makes some compressors so much noisier than others?
