[SML] Ultrasonic low fog machines....

[Ford Sellers]

Hi Jon,
Ithaca very much depends on the fluid you use. 
For instance, we tried our Cloud9 unit with tons of different formulations of fluid. 
The best looking (in my opinion) was quite similar to our professional haze fluid… when combined with the water, it made thick, beautiful clouds… but it didn’t dissipate quickly enough, and would eventually lift off the ground as haze, filling the space, and would definitely get sucked up into air ducts. 
We also tried a formula that was quite similar to our QDF (quick dissipating fluid) that we recommend for use in our vertical fogger (to simulate CO2 jets). 
It never got in the air, but the coverage was too spotty. 
Finally, we settled on a new formulation, LLG (low-lying gallon). It stays low, gives nice billowy coverage that doesn’t dissipate too quickly, and has minimal lifting into the air… but not no lifting. There is still a little that hangs in the air a bit. fog. 

If you want thick coverage that won’t lift off the ground, you may need to get an oversized machine, and use quick dissipation fluid. 

Or, stick with dry ice. 

I’m not sure that helps,

Greetings SML.....

Anyone here use an ultrasonic low fog machine? Rather than dry ice, it
uses ultrasonic mist emitter-things to create the fog (like those
Halloween tabletop cauldrons, etc). And, when using low-fog juice, it
creates more volume, but keeps it low to the ground.

Looking for experience with such beasts. Specifically, when using the
low fog juice, does it still cling low enough to the ground to not get
sucked up into the high air returns, and triggering smoke sensors in
the air ducts?

I've seen lots of videos of professional, as well as DIY machines
(mostly for Halloween/haunts) and it looks like it could be a good
solution for a low fog, that has more volume than CO2 crawling along
the stage, and hopefully not getting sucked up into the overhead air
returns.  Thoughts?
