I've been reading about folks using vacuum cleaner exhaust to power
sprayers. What sort of hose would a person fit onto an exhaust, and how do
you reduce the hose size down to the 3/8" (or whatever) size air line that
sprayers require?
Although using a vacuum sounds like a thrifty alternative to a "regular"
compressor, isn't that air a bit warm, and does it tend to clog glazes
inside the sprayer? Also, I wonder if putting a load on the exhaust of a
vacuum cleaner is hard on the machine.
We're in hardware stores quite a bit, and often see airless 110volt
compressor/air tank set-ups priced at $150 or less, on sale. The big bonus
to having a compressor around is that you can use compressed air for all
those little tasks like keeping tires and basketballs inflated, and for
blow-drying & cleaning equipment, etc.
In a pinch or crisis, it might be useful to know how folks achieve the
exhaust to sprayer plumbing. Do tell?

Ellen...
I would seriously doubt that the vacuum cleaner system would be
suitable for spraying glazes. You will most likely find that your time and
money have been WASTED. I would suggest that to do it right that you
investigate a Pasche' spray gun and a two stage air compressor, which gives
you a CONSTANT pressure, (Emglo makes a good one). You will most likely
need a spray booth if you spray inside. I think a company in the Carolinas
make them... something like Beaver Creek??? can't remember the details. I
think Axner has info on them and the spray guns as well. ...Marshall

You actually dont. Kiby Vacumecleaner were the first people to
pioneer this process, and to this day this variety o HVLP (high
volume low pressure)sprayer has a huge hose. You just have to
deal with it.

The air is warm, but that just causes your material to dry
faster. It doesn't clog any more freaquently than conventional
does although, they do tend to get some build-up on the
spray-head.

Myself, I like conventional spray. It is the easiest and most
trouble-free. It is also the best for semi-production use.

If you have a Kirby, the spray attchments can be ordered from
the company. that is the only one I'm familliar with.

Ellen,
Ceramics Monthly published a compilation of suggestions entitled: "Great Ideas
for Potters". I believe it is still available. On page 113 of my copy there
is a good description of this whole idea, including a nice sketch of the
adaptor.
My guess is that the load on the motor would not significantly shorten its
life.

Hi Ellen:
After taking a workshop with Robert Compton where he sugested using a
vacuum sprayer I tryed it with good success. I used the sprayer that
came with mom's filter queen vacuum. It is the same size as the hose.
They are said to be available at fleemarkets.

This has kind of gotten out of hand. The ONLY way a vacuum cleaner can be
used as the power unit for a spray gun is if you find one of those old
spray-gun attachments Electrolux and other vacuum companies made in the
fifties (there was a thread on Clayart recently about using these
attachments to spray glazes). Electrolux featured an extraordinary number
of crazy Rube Goldberg vacuum attachments and this spray gun was one of
them. I loved the Electrolux add in old magazines showing your average June
Cleaver housewife using the spraygun attachment to apply moth killer to
clothes in the closet. A vacuum cleaner develops relative low vacuum, and
even less pressure. We are talking WCI (water-column-inches) of pressure.
A normal spraygun needs at least twenty to thirty PSI (pounds per square
inch) to operate satisfactorily, and a fair CFM (cubic feet per minute)
volume of air. The new HVLP (high volume low pressure), guns, which operate
on only 10 PSI, are the latest rage, and while they require less pressure,
they are far more expensive. As I understand it, they pay for themselves
quickly by eliminating most overspray.
