Unique 2 Hazer from Look Solutions. VERY good output, from a light haze to almost a full "fog machine" type volume.
Hmmmm.... this sounds odd at best.
For once I find myself disagreeing with gaff...You could either trip the scrim or build an Oleo either technique would get it in and out no problem in your space.
The whole point of haze is that it hangs in the air a LONG TIME. You might be a lot smarter to think about the super quick dissipating fog and just spread it out a lot with a good fan.
If you want to go with hazers, the two hazers you'll find on everyone's short list are the Look Unique and the LeMaitre Radiance.
You might need a clarification on that ruling. The only water based fog I've ever seen is one of those little hypersonic things that was being discussed in another thread on here. All haze or fog is a combination of water and either mineral oil of Gycol. In the OLD days smoke and small fog effects were acheived via the heating of Sal Amoniac in a small pan. Very icky, dangerous, and noxious. If the Fire suppression system in your theatre is dependent on certain types of sensors , the glycol or mineral oil residue can be very disruptive. I think you may need to ask for a clarification as a hazer, say a DF-50 actually leaves more residue, especially on things high in the air, than a glycol based fogger does. Fog machine residue tends to settle, fall to the floor, Haze tends to rise and condense on things in the air.
