Hello,
Anyone have a spray booth and electric kiln in the same room?
Our guild is planning to move our spray booth out of our general working
area into a small room where one of our electric kilns is housed. However
there is some question that perhaps overspray might get into the electric
controls of the kiln and do damage. Any advice would be greatly appreciated.

If you have exhaust fans working on both of these appliances, the
spray booth fan could create too much negative pressure in the room,
and cancel out the effects of the kiln's exhaust system. I would not
expect that over spray would be a problem for the kiln unless the fan
on the spray booth is too weak.

I've had a spray booth in the same area as an electric kiln for a couple of
years. I never gave a thought to overspray getting into any part of the
kiln. First, I can't imagine using a spray booth where overspray going into
anything else is an issue. A good spray booth just shouldn't have that kind
of an overspray issue. I would look into improving your spray booth if that
is a concern.
Sorry not to be of help,

My spray booth and kiln are about 5 feet apart in my basement. Both are
vented separately but side by side through the same window. The spray booth
has a lot of power. It will pull a strip of toilet paper horizontal in the
breeze it creates sucking air past it's filter and out of the building. I
have never seen overspray outside of the hood, let alone on the kiln. The
kiln does get general dust from the studio and I vacuum it inside and out
regularly.

I haven't heard of over-spray damaging a kiln. However, I
know of elements that have burned out from fine airborne
sand.
Doll makers spread sand on the shelf to support porcelain
doll parts. When the sand is wiped off the doll parts while
unloading the kiln, the sand can fall into the element
grooves.
So, airborne contaminants right near the kiln could burn out
elements.

Hello, Eva,
I just wanted to agree with, and perhaps amplify, the point Gordon
made here a few days ago:

My studio (f.k.a. garage) is one room, aside from storage.
The kilns are on the opposite side, about twenty feet from the spray
booth, BUT...
Whenever I'm using the spray booth, I'm certain to either have the
large, overhead garage door wide open, or have my make-up air fan
blowing on its highest setting to give the spray booth fan plenty of
help to all but completely eliminate any blow back. This is for my
health and the studio's mess control.
But you made no mention of what kind of venting, if any, the kiln in
the room has. I would hope that it uses a negative pressure vent to
draw gasses the outside.
In that case, though, a more serious danger exists if you were to use
the spray booth without adequate make-up air supply while the
"downdraft" kiln vent were on. The spray booth fan will certainly
overwhelm the small fan in the vent.
And that will result in the kiln vent not working well, if at all,
thereby allowing the firing's gaseous byproducts to be sucked into
the room.
Regards,
Maurice
