Thanks for the info. Are you sure that the precipitator would need to
use DC current?
Yes. What makes you doubt this? That is the way static electricity works.
You charge up an item, and since opposite charges attract, the charged
item is attracted to a ground plane, which, from the point of view of the
item, has the opposite charge.
This doesn't happen with AC, because 120 times a cycle you're reversing
the charging voltage.
And another thing, you'd better hope that at ionizing or even
precipitating voltages, you don't have very much current at all.
I read that a corona happens more easily on AC
current,
This is irrelevant to a precipitator.
I've built the system, it consists of a box with two parallel screens
across the opening to the box, then several perpendicular copper plates
that I've connected to house ground, then a bathroom ceiling fan which
exhausts outside the box. I've ordered some diodes, but I was just
wondering if I can hook the power supply up directly, right now, and if
it would work.
It might make ozone, and it might collect some crud, but I predict that
even if it does collect crud, it'll be nowheres near the amount of crud
that you'll collect with DC.
Also, does anyone have any ideas on how to test this, to see if it
really is capturing dust and any other airborne particles?
YES! YOU TEST IT BY ENERGIZING IT AND BLOWING AIR ACROSS IT! IF DIRT
ACCUMULATES, IT'S WORKING!!!!!!!!!!!!!!!!!!! How many times do you have to
be told this?
Good Luck!
