Hi Folks:
I have two Sharper Image Ionic Breeze units. These worked good
when they worked. One broke about a year after I bought it, the second
broke just recently. Actually, they both seem to be making high
voltage, but now neither are moving air. I suspect the rectifier
diodes in the transformers are shorted. They both just hiss. The last
working unit hissed and pumped air, but now it just hisses, like the
other one. I'm hunting for a supplier for a replacement transformer.
Also, is it me or do these things suck when it comes to reliability?
;-) I did run them 24/7.

Thanks Folks!
Harry


If the diodes are shorted, I would think a 10KV would
work. Ionizers usually run up over 5KV. DC Ionic breezes
can be measured. A Neon lamp with a dual electrode wand
flashes as electrons are collected. A digital DC voltmeter
can also be used. Hold one probe with one hand, hold
the other NEAR but not touching the device. The voltage
will increase as charges are collected. If it putting out AC,
there will be no charge collected. I've had trouble lately
looking for suppliers of suitable transformers. Ozone
generators use AC, not DC.

They may need to be fast recovery/high frequency diodes.
