>I've heard that the oil-less models don't last as long as the ones that
need to be oiled. Is this true? The ones needing to be oiled tend to be
the cast iron ones. Are they any quieter than the oil-less?
The durability of the compressor depends on the cylinder sleeve, in which
the piston fits, and yes, the cast iron ones last much longer. The fact
that the others are "oil-less" is no advantage, because you only have to
tend to the oil in the cast iron compressors once in a blue moon. In my
experience, the oil-less ones have been no quiter than the cast iron ones.
A better quality compressor will be better balanced, and therefore quieter.
Also, the greater mass of the cast iron compressor may absorb more noise,
making it quieter. I have an old Campbell-Hausfield I bought about 25 years
ago and it has never missed a lick. I draing the moisture from the tank
regularly, and I change the oil once a decade or so.
>Do I need a 20 gallon, or would 13 be adequate? I'd like to wheel it
outside the basement and up a hill to the driveway so hubby can air wash his
vehicles.
If you get at least a 3 to 5 HP compressor (motor size) then you can
probably get by with the smaller tank, but make absolutely sure it has an
automatic pressure switch, so that the compressor starts up whenever the
tank pressure drops below the preset minimum level, and shuts off at the
preset maximum level. And if your husband wants to do some air cleaning up
the driveway, all you need is a long air-hose. Personally, I'd get the
larger tank and move it around less often.
>And, what about this HVLP stuff? Is that just the sprayer and it can be
put on any compressor, or is there a special compressor? I'm not starting
out that fancy, but would like to have the ability to upgrade later without
having obsolete equipment.
They do make HVLP spraying systems with special turbine compressors, but
they are very expensive, and are only for that purpose. You can get HVLP
guns which have a step-down regulator on the handle of the gun, which
reduces the line pressure to around 10 PSI. The HVLP gun is a real
advantage, because it drastically reduces overspray - much more glaze ends
up on the wares, which saves a great deal of money in the long run.
Don't buy a low-budget off-brand compressor. You can get excellent
cast-iron barrel compressors for very reasonable prices from Quincy,
Ingersol Rand, Speedaire, and Campbell Hausfield. The latter is probably
the least expensive, but make sure it is their cast-iron line. If in doubt,
bring a magnet and check the compressor barrel (the vertical part with the
horizontal fins on it). If the magnet sticks, the barrel is cast iron. The
cheapo ones are pot-metal, and the magnet will not stick.
Good luck -

on compressers- if you wish to move it any distance do make certain you have
the right voltage in your situation to accomodate the compresser as a 220-240
extension cord is, not at least readily available to my knowledge;in any case,
extension cords are only good for a limited range and sizing any cord to the
draw capacity of the machine it is being used for is extermely important.If
you opt for a gas powered compresser remember to only use it in a properly
ventilated area to avoid carbon monoxide poisoning.If the compresser is
stationary 220 is cheaper to operate than 110 for extended or frequent use.

Silent-aire I think comes from Texas or used to. They
make wonderfullyquiet air compressors and I do own one
and have for years. Its been a dandy! The shark I
think was named after an old friend of mine Mark the
Shark in PCB. It should handle the air pressure you
need without flaw. I done some vendor shows with that
company when I was still in the manufacturing
business. Good people and I believe the business
originated in Italy when it started.

The problem is that these little "silent" units cannot
keep up with a decent
spray gun, and they generally do not have a storage
tank,
Hi - I run 60 pounds of constant pressure with a
minimum drop at full speed. THe Shark and others
similar in the silent end do have tanks. The flip
side, as Vince states you might be better off with a
heavy duty for lots of hard working spraying but the
newer silent compressors are made for all day spraying
at 40-60 pounds PSI for artists and do come with
tanks. They're expensive because you can use them and
the person next to you won't hear them running. Those
little compressors that are direct drive air are a
waste of time and effort for applying glazes. There is
a specific difference between the top (3) compressors
outs there. Direct air, no tank and usually fizzles
under pressure. Silent - Can be small to large and
usually will have a tank of some size based on model
involved. Belt drive- you can airbrush a shirt, spray
your pots and then take wheels off your tractor for
plugging a leaking tire.
