Re: Guide to electric air compressors for home shops



from rcm, inneresting point below. most of the thread debated oil vs
oil-less in painting apps.
Apropos of the thread some time ago on cost of air.

..There are six things you need to know about compressors:
The maximum PRESSURE that it develops, the rated VOLUME it
can deliver, the amount of compressed air it can STORE, how
LONG the motor can run (which is also known as "duty
cycle"), how much electrical POWER it's going to take to
run, and how much NOISE it's going to make....

All the advice in the article is good stuff. One critical point is
missing, however, The author should have added a section named
"Delivery". More power is wasted by undersized or over long hoses and
restrictive couplings than any other feature. The ubiquitous 1/4"
Milton M fittings almost everyone buys are serious offenders in that
respect. That is why so many shops for years kept buying air
compressors with higher and higher tank pressure ratings. The
currently popular 175 PSI rating is absurdly dangerous because design
parameters of most air tools are by regulation pegged at 90 PSI.
Milton some years ago introduced the "V" series plugs and couplers.
These have substantially higher flow rates than the "M" series which
98% of the lads reading this now have in their shop. The specs are
listed in the Milton catalog available (PDF) online. I converted my
shop some time ago when they were first introduced to improve my HVLP
paint systems. Couple this with a good quality 3/8" air hose (throw
out those wretched 1/4" hoses) and a modest 125 PSI compressor will
serve you very well for everything but removing earth mover wheels.
The laws of physics will work for you if you let them.
