What is this?

Starting rehearsal in a space used by the local Gilbert and Sullivan company ( ie voice preservation is important to them ).
There are two of these devices in the room. About once ever 30 seconds or so it would make a "zap" noise like a bug zapper.

Our artistic director said it is a device to control static electricity and that this helps the singers voices. Anyone have any ideas about what this is, how it works, and what it is doing?

Thanks for the ID

The manual says an occasional snapping may occur,. I have no idea when the units were last servicespd.
 
It's better than the ones that pump ozone into the air. How that's good I don't understand. On an interesting sidenote, should you find the need for poor man's air purification I'll share a trick I discovered at a cigar shop that allowed you to smoke in the store. They took several box fans (the $12 type you find in HD or Lowes or Walmart) and affixed a furnace air filter to the intake side. The owner claimed it kept his counters from getting too sooty, but I would wager they'd work in a pinch anywhere you want to clean particulates from the air.

Of course the internet has some info- http://lifehacker.com/5976491/make-a-simple-air-purifier-with-a-fan-and-a-furnace-filter
 
Some vocalists will believe anything. I used to tell bands I was using a modified smoke machine that also output vapor like a humidifier and it was good for their voice.
