About six months ago there was discussion of the Dyson on Clayart. It's
claims seem to be grossly exaggerated. Basically, it would do an excellent
job of sending all the finest silica particles (the most dangerous ones)
back in to the air for you to breathe.
There are some very expensive portable vacuum units available like the
Nilfisk that are HEPA rated, and they will remove the fine silica particles.
However, filters must be changed frequently, and they are expensive as well.
The very best solution is the stationary vacuums that have been discussed.
The stationary cannister unit filters out the coarse stuff, and then the
unit vents to the outside, so the fine particulates are not an issue.

Hi All
I'd like to hear about central vac systems which are suitable for a clay =
studio.
The central vac in our house is a Kenmore which uses filter bags and is =
totally unsuitable to use in our studio as the bag will clog almost =
instantly.
So, we do a lot of wet mopping. However, I find that isn't particularly =
effective except in the middle of the floor - pretty hard to wet mop in =
the corners.
Watching the Discovery channel a couple of nights ago I saw the new =
DYSON vacuum which, according to the owner, uses a cyclone so fast and =
powerful that even the tiniest particles get taken out of the airflow =
and into the "dust collection chamber" (I don't recall the exact words). =
This was an upright vac, not a central unit.
Any ideas / recommendations are appreciated

Hello,
The best studio vac that I have found is the Beam, which I purchased from
Marc Ward in Tennessee (he shipped it) more than 10 years ago. It is a
central vacuum system, and is externally vented so that no fine clay
particles are floated in your studio. It cost me about $400 then, and I
have no idea what it costs now. Marc's catalogue is online, so you can
check it out and see for yourself.
Over the years, I've tried the Nilfisk system (expensive system, needing
filter replacement often, which was very very expensive, and which didn't
work as well as the Beam), an industrial system that included a huge
inflatable filter bag (won't even go there...it was pretty ludicrous), a
Sears five gallon wet/dry vacuum (clay gunked up the water pretty fast) and
the Rainbow system (ditto with the clay fouling the water and the system).
In my studio, I use the Beam vac as a prelude to a wet mop. I believe in
keeping the dust down, and as I spend up to 30 nights a year sleeping there
when I've got a kiln in, I want it to be as clean as my living space. When
I wet mop, I use an industrial bucket and mop so that I'm not just slopping
the clay around the floor, and always add a cup of bleach to the mop water
to disinfect as I mop.
Best,
Richard Aerni

I agree with Richard that this--at least for me--is the best way to
go. I have an Electrolux 1590. The unit sits outside the studio
protected by one of the plastic storage lockers. 99+ % of the dust/
dirt is collect in the tank (no bag). A tiny bit collects on a
cylindrical foam filter which seems to have a amazing capacity to
still pass air even when clogged with a 1/4 inch of dust on the
outside. It needs cleaning every so often and replacing can cost from
$10-$45 depending on whether you buy OEM or after-market filters. Of
course the tiniest dust passes through and is released outside. I
have been very happy with it. It hasn't caused me a bit of problem--
other than emptying it and cleaning the filter once in a while--in
several years. Like Richard , I then wet mop with an industrial
bucket and mop to clean up additional dust.
Regards,
John

I agree with Candace. I too, have a Dyson, the yellow one and I wouldn't trade it for the world. I am finding that is sucking up old dog hair from years ago that I didn't even know was still in my carpet. It lifts the nap of my old carpet and doesn't just push the dirt and dog hair around and around on the floor, pushing it deeper into the carpet. My old sweeper always left the smell of old dog hair in the air, my Dyson keeps my home smelling clean, you'd never know we have two dogs in the house. I've had several different brands of sweepers and this ones the keeper of them all. I doubt you'd have any trouble with the clay dust.

Hi John,
Why not run it without the bag?
I use a beam - get the heavy duty kind.

Great to hear these testimonials about the Dyson in household use, and
please don't take this as any kind of scolding, but this discussion has to
do with vacuums in the ceramic studio. As was pointed out, the Dyson might
do a great job of sucking up pet hair, but if used in the clay studio it
would also do a great job of putting all the highly toxic fine silica
particles right back into the atmosphere for you to breathe.
I would hate to see anyone misinterpret those positive testimonials about
household use of the Dyson and think that they might be appropriate for
studio use. They are not. Listen to all the long-time Clayarters talking
about how much they love their Galaxy and Beam stationary vacuum systems for
studio use - the ones that vent outside, so there is NO chance of
introducing any fine particulates to the indoor atmosphere.

If you keep the EXIT filters on a Dyson up to scratch there is no
problem with ultra-fine particles, provided of course that they are
Dyson filters and not anyone else's.
Dyson are approved by the British Allergy Foundation; they wouldn't do
that if they let anything like silica dust through!

Just to add my two cents to the discussion the Dyson vacuum cleaner and to
agree with Vince, back in my engineering days we used all types of cyclone
dust collector systems in our coffee plants. They were probably of a much
higher efficiency than the Dyson could ever achieve (efficiency is related to
velocity, particle size and density) and inevitably they were backed up with bag
houses to remove the very fine particles. Using the Dyson to handle clay dust
will most certainly assure that your lungs are exposed to only the finest ,
most hazardous silica particles.

It is my understanding that the Rainbow vacuum was designed for household
use and is completely unsuitable for clay studio use. It simply cannot
handle the volume of dust, and I believe that it will not even filter out
the finest silica particles at all. This unit has been discussed on Clayart
before, so you can probably find information in the archives.

So, what about the "rainbow" system? Really expensive, I know, but given
that it uses water as the filter, what's the likelihood it'd work for clay
dust?

It doesn't do squat, for clay dust or even the
regular dirt. The air bubbles through the water,
and whatever dust is on the sides of those
bubbles gets trapped, but all the dust suspended
in the middle of the air bubbles gets sent right
back out. Tests seem to show that the Rainbow-
type water vacuums aren't even as good as the
ordinary type of vacuum cleaner.

Thanks, Vince. It seemed somewhat improbable that it would suffice, but you
know, my old brain cells said "hmm, water in vac, clay dust in vac, clay
dust in water, could be..."

Phil, I had thought about the Rainbow vacuum cleaners myself. Since =
Vince
talked about the volume of dust, part of the problem is the surface =
tension
of the water in the tank IMO could be made more acceptable of more dust =
if a
wetting agent was added to the receiving water. I don't have or never =
used
this machine but even felt that a Shop Vac Wet/Dry system, the wetting =
agent
would or could possibly accept more of the dust. Just a thought. The
wetting agent I would use would be a few drops of Basic H.
Respectfully,
